Well after trying to get my jetting right on the 01' RM 250
it seems to be running better (no more bogging) but still doesn't seem to have the power it should... I've got about 8 hours on the rings, and It hasn't "appeared" to be burning any tranny oil. The bike is still spooging alot though even with new silencer packing running yamalube 2R @ 32:1, after one 5 minute blast around the trails you can already see it accumulating on the rear fender a bit. I thought if it was burning case oil you would at least smell it, and it doesn't smoke a whole lot either which is weird. If worst comes to worst and I have to replace the crank seals do the cases HAVE to be split? I could have swore I heard someone replacing the wet side seal without having to split the case, but I may be dreaming? What about any oil additives, are there any that might help expand the seal or is that a bad idea? I've been running 10w30 mobile one, but I think the previous owner was running a thicker gear oil. Would switching oils cause the seal to go bad faster? I just want this bike to run right, i hate riding it knowing there is most likely an underlying problem... I also noticed some smoke coming out the pcv valve hose the other day, but then I seen a brand new gas gas 250 doing the same thing so I figured it was normal? Thanks for all the help guys... :bang:
