Hey all,been having the same issues for a while but this past weekend,while racing it got considerably worse.Below are the symptoms and below that is what ive done so far.
Symptoms:
Issue started out as a dramatic increase in vibrations to the handle bars while riding for more than a couple of hourse and especially when riding with the throttle pinned on long straights or roads.At the end of the day it was super bad,bike was always just screaming while not producing a huge amount of power for the amount of revs.
Have had issues with clutch slipping but bled it super well one week ago and that seemed to solve the issue.I was once again able to actually start in gear,although i was still getting the bad vibes.
This past weekend,i raced a very gnarly enduro and in the tougher sections the clutch got real bad,most easily identified symptom was that the clutch wasnt able to be feathered any more.It was either engaged or not at all.And it would only engage in the last half inch of lever release.Riding like that was tough.
I could also swear that while in the worse sections,while feathering the clutch i could hear a terrible rattling from the engine.
Bike had great power throughout the race,no issues there.
What ive done to fix it:
tried different oils,from 15-40 Amsoil dirtbike oil to 15-50(recommended for KTM) then back to Motul oil and back to MOTOREX(currently in the bike is amsoil dirtbike oil 15-40)
Ive bled the clutch to the degree that i would say was well bled.
Fully drained the system and blew air thru it all and re-bled.
Note:There are a few things i think it could be.I havent changed the damping elements.And also(this is the likely culprit),the black rubber cover on the slave cylinder piston is "chipped",its missing a small piece of rubber on the side.ill take a pic today or tomorrow.
Thanks for any help
