Lowering spacers

$
0
0
A machinist friend has offered to machine the delrin shock lowering spacer for my rear CRF shock.

I am seeking advice on the best way to accommodate the need to keep the bleed hole open and it's flow unrestricted. Pictures would be very helpful.

I've seen images of a nice countersunk metal spacer which leaves flow apparently unrestricted. Would delrin be strong enough if machined like this? Is flow still restricted somewhat?

Have any of you machined a new base plate including the spacer?

Other thoughts?

Thanks a lot.

BETA DUAL SPORT/ADVENTURE BIKE SETUP: RS390, RR-S390, RS500, RR-S500

$
0
0
Interested in a light weight adventure bike that doubles as a dirt bike? Plenty of enduro bikes can be adapted, my all time favorite was the Husaberg FE570 but sadly it's no longer made.  When I got the Beta RR480 heaps of guys asked me whether it was a good candidate... here are the results.
 
 
WHY THE RS390 & RS500?
All the Beta four strokes are proving to be very solid reliable bikes but the 390 and 500 tend to be the pick for dual sport or adventure conversions. See Traction eRag's excellent 2017 Beta review... here's a summary:
Beta 350 short stroke engine, loves to rev, ultra responsive, not much low down grunt.
Beta 390 longest stroke, super user-friendly, grunty, smooth, an all rounder.
Beta 430 the enduro weapon winning the european championships.
Beta 480/RS500 the gentle giant, monster talk, less revvy than the 430.
 
WHAT'S HOT
I was keen to see how the Beta 390 and 500 would shape up, with a few things making the Italian princess a sensible choice among a range of good contenders....
- lower seat height
- very user-friendly engine and handling characteristics
- very wide ratio gearbox
- double overhead cam engine for smoothness
- fuel injection for altitude or temperature variations
- dual engine and transmission oil providing a higher overall capacity
- long term reliability for the engine and gearbox.
 
WHAT'S NOT
What's not to like about the Betas for dual sport or adventure riding? Mostly the usual problems faced with any enduro bike:
- uncomfortable seat
- small fuel tank
- rear subframe too weak for heavy luggage
- weak headlight
- RS500 engine a bit too snappy off idle
- 100 hour plastic oil pump gear life (more below).
 
FUEL TANK OPTIONS
We ordered the IMS 11.7L (3 gallon) tank for US$290 for around 300km or 190 miles of easy adventure riding.
Apparently IMS now have a 4 gallon tank which is great for anyone wanting even more range.
An interesting idea is this Behego 'plug & play' rally tank, which actually wraps around the lower half of the engine and could be good if like to keep a low centre of gravity when adventure riding, and just take it off for dirt riding. It comes with its own bashplate.
Clarke Racing do bigger tanks for the pre-fuel injection models.
 
SEAT, PEGS & ERGONOMICS
Seat Concepts is the most popular choice for Beta riders, starting at US$174. Would love to have tried this but they never answered any of my emails. clear.png
A fun budget option to try is buy a block of medium density foam and cut your own comfy seat and staple some vinyl over the top.
Enduro bikes have quite small footpegs, the Beta is no exception. It might be worth looking at the Fastway pegs which provide a bigger platform, and can also be dropped down and back to give you more leg room on the bike.
We've done vids for short rider setup here, and tall rider setup here.
 
ENGINE
The RR390 has a long stroke engine that loves to lug and has an even more user-friendly nature than the RR480 - if you don't need ridiculous amounts of top end performance this bike is the one. To me, it's what the DRZ400 could be if Suzuki gave the engine is serious makeover.
The RS500 is not a scary bike, and has actually been called the gentle giant by many... monster torque and only goes crazy once you really crank the throttle. However, like most big fuel injected thumpers the throttle response is snappy from idle. I highly recommend the G2 Throttle Tamer for only US$70, it transforms it into a kitten at small throttle openings. See our review here.
 
The benefits of fuel injection are clear - better fuel economy and automatic adjustment to elevation changes. The down side? It could be worth fitting a fuel filter sock in your tank for adventure riding in case you got dirty fuel in remote locations.
 
While many debate the usefulness of dual engine and transmission oil chambers, it does mean a higher capacity of 1.5 liters overall, and on a very long adventure ride you only need to carry 750ml to do the engine oil at 30 hours, as the lack of clutch slipping should mean the transmission oil will be fine for a lot longer. Logic would suggest you could extend that 30 hour oil change if you aren't pushing the engine hard, but by how much? I'll leave that up to you. Even 30 hours should get you 2000km of dual sport riding before an engine oil change.
 
The only real drawback with the Beta four stroke engine is the plastic oil pump gears. These should be replaced every 100 hours, most riders are putting the metal gears from Boano in and then they can forget about them.
 
ADVENTURE KNOBBIES
A huge range of options here, starting with the cheap Dunlop D606 and Pirelli MT21 to all sorts of hybrid and adventure tyres. I was very keen to try Goldentyre's new adventure GT723 but it's not in Australia yet. On his around the world tour Lyndon Poskitt has been reporting an incredible 7000km lifespan even with a lot of high speed road work. Instead I opted for a hybrid rear tyre, the Shinko 505 Cheater. Great grip on the road with it's soft compound and close set knob pattern, and seems to be wearing well too. Most of our guys are using this now and loving it. See our Shinko review here.
 
One thing I would highly recommend on the front is a high profile front tyre. I'm running the Goldentyre GT216 'Fatty' 90/100-21 which adds to already excellent inline stability of the Beta at speed. A lot of guys fit steering dampers to enduro bikes for dual sport riding but I think this tyre is an excellent alternative. For any highway riding, always get your tyres balanced properly, or those rim locks will have you shaking your way down the road.
 
In the USA TUbliss are not approved for road use but personally I hate punctures... the TUbliss setup lets you continue riding if you want, or simply pull out your TUbliss repair kit and plug that hole - two minutes later you are on the road again. Lovely.
 
LUGGAGE
Luggage is always tricky on enduro bikes. That weak rear subframe means you can't hang a lot off the rear. And you don't want to anyway, these bikes are so light they handle very strangely if you don't keep the weight centred.
 
The budget option? I used to to just strap dry bags to the side of the FE570 which centred the weight nicely and kept it low. Next budget option is something like this Third Gear luggage bag which is only AUD$75 here in Australia and works great on enduro bikes. Then you get into the good stuff, Kriega, Wolfman, Giant Loop, Nomad Rider.
 
You can spend a lot on soft panniers, tank bags, fender bags. The key is keeping that weight centred and ideally, down low. A handy aspect of the Beta is those rear grab rails under the seat which make excellent mounting points for luggage.
 
There is a rear luggage rack for the Beta from Nomadic at US$170. See pic in the second post.
 
ELECTRICS
Good news here, the stator is relatively strong for an enduro bike with 200W at 6000rpm so can run things like heated grips without draining the battery. That weak headlight? By enduro standards it is actually quite good, but if you plan on riding at night it will pay to upgrade.
 
The LED lights have finally come of age, and personally I think it's worth bypassing the HID lights and skip to something the like the Cyclops LED headlight... only US$65 and a ridiculously bright 3600 lumens on high beam that only draws 40W.  And you can almost double that for an extra $10. LED light bars have also dropped dramatically in price and could be worth looking at.
 
DO YOU NEED A CUSH DRIVE HUB?
Do you need a cush drive hub? There are cases of KTM enduro bikes eventually wearing the countershaft splines with extended road riding, and by extension the Husaberg FE570s... even with a cush drive hub my FE570 countershaft was looking quite worn by 12000km. I've checked around and there are no known issues with adventurised Betas in this respect... but if you plan on a lot of road miles I would still consider a cush drive hub. Here is my reasoning.
 
Dirt bikes don't have a cush drive hub in the rear wheel. Road bikes typically do, to ensure smooth running and less stress on a gearbox, sprockets, chain and rear tire. My very tentative conclusion? There is probably less need to fit a cush drive hub if:
- your bike is under 600cc
- you don't plan on clocking too many miles on the road
- your bike has a solid gearbox and countershaft
- you don't lug the engine at low revs on the road.
 
For more info, see this advrider thread.
 
PROTECTION
This RR480 has all the usual gear you would expect for dirt riding such as handguards.  Mostly I use the heavy duty stuff from Aussie mob Force Accessories - radiator guards, bashplate, case saver. For light adventure work this may be overkill, but for long trips it pays to minimise your chances of damaged radiators and engine cases. I particularly like the case saver, just in case that chain snaps then holes your case in the middle of nowhere and the hand guards are great for not worrying about clutch and front brake levers if you drop the bike. Of course you can carry spare levers, but anything that prevents breakages in remote areas is a great idea.
 
OLD MAN SETUP
I'll do a whole vid on this soon, but lots of us adventure riders are old farts! If you like to stand a lot, these Steg Pegz take a lot of strain off your upper body. Ditto for these Twisted Engineering flexible handlebars I'm using on the RR480, or the Fasstco Flexx bars I have on the DR650. The Clake One Light Clutch can reduce clutch pull by 75% and is brilliant for arthritic old hands.
 
ANYONE GOT FURTHER TIPS?
Got more tips? Post them here and I'll include them in this post for easy reference.
 
That's it to date... so far the RR480 or RS500 is proving to be a pile of fun as a light weight adventure bike. As I said, other bikes can do this too. Adam Reimann successfully took a KTM 500EXC all over Europe and down to Egypt. And many guys here in Australia have adapted the Yamaha WR450F with good results. But I do think the Beta has a lot of features that make could make it the ideal choice for many as a light weight adventure bike.

4mm stroker?

$

Hey guys, quick back story i bought a 2001 drz400e with a blown up engine, now at first glance it appeared that it needed a top end rebuild, Piston kissed the exhaust valves, so i got the value seats machined and the gasket face machined aswell, heads back together and ready to go. I also bought a cylinder works 434 big bore kit.

After removing the stock piston i noticed the crankshaft has a ton of play, so now its time to split the case replace the crank and while im in there I'll replace all the bearings as well just for peace of mind. Now the question is will it be worthwhile getting a 4mm stroker kit? Or will that involve a lot of extra work? Carb? Head work? Valves? Cams?

would my current set up with the 39mm fcr carb, E cams and later on a mrd exhaust work with the 4mm stroker?. The engine is out of the bike and on the bench waiting to be worked on.

Or should i just keep the bottom end stock?
Thanks.

Just curious if this is an OK bike?
It would be for me and my 14 yr old son to both learn on. I wouldn't mind a bike I can ride on the dirt roads near my house or be able to drive from my parents to the trails when I'm up north visiting them.
Thanks for your input.

Opportunity to buy an 06 CRF250r or an 07 CRF250r

Hello all,

 

I have an opportunity to purchase either an 06 or 07 CRF250r.  Both are priced within $100 of each other.

 

The 06 is all stock and in VERY good condition.  Just serviced by a shop prior to be putting online.

 

The 07 has new tires, black rims, red hubs, renthal bars, sprockets and skid plate. 

 

Motor and exhaust on both are all stock.

 

Aside from the obvious 1 year difference and the noted minimal upgrades on the 07, which bike is better?  Is there, was there any difference between the years?  

 

Thanks!

 

 

 

 

70:1 premix?

Hi,

 

I have a 2016 Beta 300 evo 2T.  The owners manual says to mix at 70:1.  I also read that Vertigo recommends to mix at like 100:1.  I am new to trials but not new to 2 strokes.  I am curious why the premix ratio is so lean on trials bikes.  Any insights from other trials riders?  Is there any harm in going 50:1?  Why so lean?

 

Thanks!

Hey guys so I have been told my 2014 yz 250f is about to go boom [emoji95] and I have been quoted around the 2000 to get it rebuilt but have come up with a idea of putting a yz 2 stroke motor in the frame either a 125 or 250 but was wondering how it would work with the new frame and how I would work everything. Is there anyone out there that has done it in the newer frame that can help of people that have heard about it IMG_1484344228.917911.jpg

**If you receive an "Internal Error" after you submit your comments, please hit the "Back" button on your browser and resubmit.**

The Office of United States Trade Representative requested comments on Dec. 28 regarding its proposal to include tariffs on motorcycles imported from the European Union with an engine size between 51cc and 500cc in the E.U. - U.S. beef hormone trade dispute. The deadline to submit comments is Jan. 30.

The American Motorcyclist Association opposes the proposed tariff, because trade disputes residing within the boundaries of the agricultural industry should not be solved with trade sanctions levied against non-agricultural products.

Specifically, a 100 percent, or higher, tariff on these motorcycles is proposed. This will cause serious and potentially irreversible harm to American small- and medium-sized business owners selling the vehicles. Additionally, consumers will be denied access to certain models of competition and recreational motorcycles that contribute to the lifestyle and wellbeing of millions of American families.

Manufacturers that will be impacted: 1) Aprilla; 2) Beta; 3) BMW; 4) Ducati; 5) Fantic; 6) Gas Gas; 7) Husqvarna; 9) KTM; 10) Montesa; 11) Piaggio; 12) Scorpa; 13) Sherco; 14) TM; and 15) Vespa.

Should the availability of product be hindered through unjustified trade sanctions on European-produced motorcycles, dealerships may close, leaving countless Americans without jobs.The negative effects of the proposed trade sanctions will not only harm the motorcycle sales industry, but will spread through the aftermarket equipment sector, recreation equipment sales, the sports entertainment industry and further down the line.

Solved Most Recent Valve Issue

I was practicing full lock turns in the driveway yesterday and my bike died. I couldn't get it to start at all so I pulled it apart and checked the valve clearance. The odd thing was all were in spec except the right intake,measured at .019" with a 1.85 shim in it. The calculator said to put a 2.00 shim in. So I did that, still wouldn't start, checked clearance again and at.014" still.

I figuered something was wrong so called my buddy who is the parts manager ah my local Honda shop. He suggested pulling the head and brining it in to check out.

I got the head oout in no time turned it over and see this...IMG_2305.JPG

That would explain the insane gap.

I bought this used and it had an opened air box already. Some how that piece of air box migrated from the air box through the carb and into the head, is that even possible? Luckily it had a curve in it so it didn't drop into the cylinder.

IMG_2306.JPG

The valve stem isn't bent, got it back together with the original 1.85 shim and it started right up.

Thinking about a new project. Thought a XR600 would be fun to build up and do a few races on. What was the hot setup for these bikes back when they were new? The XR650R is prett well documented and all the tips and tricks are all over the Internet. Everything the suspension valving, factory tricks, and more. Not so much for the 600.

Outside of suspension, were there any other must do mods to these bikes?

Anyone still racing their 600? What's your setup? I'm not looking for winning, just a second fun bike....that just might surprise a few guys when it shows up to the starting line.

Rekluse Core EXP "Free Gain" Issues

$

I have a 16' 450FX and installed a Rekluse before I ever rode it. I've installed about 4 Rekluse clutches on previous bikes although they were all KTM's w/ hydraulic clutches. I've installed it and set everything exactly the way it states to in the instructions and video.

 

My problem is, after about 6-8 hours of riding or less, I start to lose my free gain and it starts to slip pretty bad. I have to redo my pressure plate adjuster and then it's OK for another 6-8 hours... I'm tightening the pressure plate adjuster until it gets tight... I double check to make sure there is still slack in my clutch lever, which there is. I then turn it one complete turn then two clicks. I then tighten the set screws to 40 in/lbs. 

 

Any suggestions on what I may be doing wrong? The plates look good and don't have much wear on them. One thing I've been meaning to do is call Rekluse to see if I should be using more oil than the what the manual says. I thought I read somewhere that the Rekluse clutch cover is larger so you can use more oil. Any truth to that?

I have a 2006 kx450f. I recently filled it up with fuel an the cap off the fuel drum fell in so i went to grab the tools to remove the tank an get the cap out.. (pretty much only thing to do!)
But got side tracked an a mate started it aan i immediate yelled to turn it off lol
So removed the cap an all sweet !!
Took it for a ride for 5mins an she cuts out.. so i freaked an assumed something maybe blocking the lines so i checked over the cap that fell in an its still 100% intact so nothing has flaked off. Changed the spark plug after i got home but still wont run.. it kicks over on choke an take choke off it dies. Or when i touch throttle?? Or it will start an run for 3 seconds then die. Please help as i got no idea???? Surely the cap falling in being ridden for 2mins then taking it intact couldve done much damage??
Cheers guys!!!!
