WR250F which oil to help with common clutch issues?

Done a lot of searching on the net, and it seems my clutch issues are pretty common-

* creeping in gear with clutch in
* Hard to get neutral
* No clutch slippage at all under load...
* Cable adjusting not working


Anyway, ive read there is certain oils which have better characteristics for helping clutches grip.."friction enhancers"???? cant remember what they were...

Anyway anyone have any experience with this and an oil which helped?

Thanks in advance.

Hello Emma

Not sure if these issues are WRF specific, I have seen these issues on many different bikes. Both my 03 and 07 model suffer or suffered from the creeping and hard to get netural and various stages during a ride I assume something to do with how hot the clutch is. Steel expands when hot etc.

I do know the 07 models suffered from the steel plates in the clutch warping but mine seems to have been ok. I am fairly easy on the clutch though. The other issues I just live with.

Ive heard of this issue with brand new WR's so i don't think its anything i can "fix" so was after info on how to improve it, which apparently can be done with oil.

Bought my brother in law a 06 wr250 with exact same problem. A combination of the following fixed the issue:

1. Pulled clutch to make sure nothing was warped or glazed.
2. Adjusted clutch at perch and adjustment at the other end as well.
3. Motul 5100 oil
4. Idle must be set correctly.

Problem solved.

this blokes got the right idea. pull it out and check it, then reset in place. use a good oil . my 07 been great in that area. always used motul oil and change every 2nd ride. goto look after the bottom end + gearbox.

Sorry Emmett, my mistake, one to many beers last night.

My bike has always run Motul 5100 as well.

what year is your WR ?
what oil are you running now ?
how often do you change it ?
how often do you change your oil filter ?
how much 'play' is in your clutch cable ?
how many k's on your bike ?


cheers

My 05 has a tendancy to grab... I run silkolene full synthetic and it seemed a little smoother on the box than motul 5100...

I believe the cause for the common prob with these wr for grabby clutches had something to do with poor machining on the pressure plate, causing variances on the spring tension. I havent checked this out yet myself but remember reading something bout it on thumpertalk.

Anyways, just set the freeplay, run a good oil and ride it.. If it worries you that much pull the clutch cover and inspect. Just remember to keep the plates in order as well as relative position... wrap them in a zip tie in exact same position AND order as removed. Remember to check for grooves in the basket and torque the springs to spec. Glazing will cause slipping not grabbing, but look for warpage.
