Is it possible for sag to be set already from the dealer?

$

0

What I mean is, I recently acquired a new 250xc and when getting the measurements for setting the sag it seems the bike is already at 100. Is that possible?? Or did I measure something wrong?? I will admit I have been riding all my life but never took the time to check the sag since all my previous bikes were used and I was young and just wanted to ride LOL.  


Valve Longevity?

$

0

I have a 07 250x and just had to reshim one intake valve and not the other.  I know it will need a valve job soon but my question is if I go to stainless valves and have the head redone, how long will it last?  I trail ride and just started harescrambles but I rarely - if ever-  hit the rev limiter. I don't mind putting the money into the bike if the solution will last a long time.  IMO, this is a weird problem and can't believe a Honda engine has such a problem.  How long will stainless valves and new/redone seats last?  I don't want to keep pulling this apart every year. 

 

Is this a problem with all modern 4 strokes or just the Hondas?  when I had to reshim and saw about the titanium valves and the valve problems, I'm thinking I should have bought a Yamaha... 

Keeping your own lap times

Interested in doing this.  I ride with a small G-Shock watch (DW-5600EV) as it's super durable, light, and pretty small with plastic casing.  Has timing, countdowns, and the ability to view current time during running those features, but the buttons are small as heck, so impossible to actually hit when I'm riding.  If they were bigger I could likely manage.  Anybody keep there own times using a wrist watch?

Ideas?

I have a 2010 yz250f and it seems like its not running right. If I'm in neutral and I rev it a little bit it like bogs down for a half a second and then it revs up.

Got this exhaust flange from MSV racing for my CR500. No more leakage, and it is lighter too. Has an O-ring against the head, so no need for a gasket. Mine is ceramic coated. $89 + shipping. Came to 90.35 shipped for me (I live close to him.)

Valve Lifter Bucket Service Limit

In the process of rebuilding a 2004 250R and found that both intake valve lifters are right at their service limit of 0.885".  I'm inclined to replace them, but these suckers are $30 a piece so I'm a little hesitant.  How critical is the O.D. of the lifters and what's the worst that could happen if I re-use them?  I'm curious what the O.D. of a new one is.

4CS Fork spring change?

I have a 13 250 xc with 15 4cs forks. I weigh 225 and would like to change the fork springs. Can I just change the springs or do I need to have them revalved along with the springs? If anyone has any experience, how hard is it compared to an open chamber fork?
Thanks,
Matt

Hello. I was wondering the best size to run on a yz125. I believe I have 100/90-19 front and probably 110/90-19 on back, but I'm currently at school so I will update when I get home. What does everyone else run on theirs? Thanks

Fixed my flat tire, then bike wouldn't start:-(

Got a front flat out riding today, so I pulled over, laid the bike down, took the wheel off, and fixed it, then when I righted the bike again, it would not start for the longest time. Took me maybe 15 minutes to fix the flat, then had to wait another 45 before the bike would fire up. It must have flooded while being on its side all that time. I took off side panel, removed air filter, and squeezed out a LOT of gas. Then let it dry in sun for a while. After maybe 25 times of trying, over 45 minutes, the bike FINALLY fired up. Whew! Big relief! So I reinstalled the air filter, secured the side panel, and headed down the road.

Anyhow, here's where I need advice: what's the proper procedure when laying the bike down to fix a flat on the roadside, to improve odds of bike firing up when ready to go? I did not shut off petcock. Should I have? Should choke be used when bike is righted? Should carb be drained before trying ignition?

I have a 2013 DRZ400S, all stock except for safari (18L?) tank. If my battery had been just a bit weaker, I'd still be out in the woods!

I'm thinking about upgrading my kdx 220 to a ktm 200. What will be the biggest differences and how will the ktm 200xcws bottom end compare to the amazing kdx 220 bottom end? Also maybe interested in 250xcw but I'm leaning towards the 200.
