View Full Version : Clunk on take off!
09 XP X with RER, new to me this season and it's clunked from a standing start since I got it. Doesn't happen though if I ease the throttle. Can't remember if my old 05 REV did the same.
I thought nothing of it 'til a buddy with a new M8 (his doesn't clunk) after riding my sled mentioned it, and now it's got me worried. Primary was overhauled about 250kms ago and I always blast it with compressed air after a ride.
Should I be worried? Clutch or just ratcheting.... any thoughts? Cheers.

Just after you come out of reverse? check chain and or tension.
Not just after reverse. It clunks when I throttle and the clutch engages. If I'm really light and progressive on the throttle it doesn't clunk.
My chaincase adjustment is finger tight and backed off a bit.

something in the primary. Sticking levers, spring cup, buttons in right with orings ??
M8 buddy thought spring cup too.

What was your previous sled? Try not comparing brands. My 2010 XP has a harse engagement compared to my Polaris. Clunk noise might be characteristic of the clutch setup.
05 REV. I can't remember if it clunked or not.
Just spoke to a friend with an 08 XP, he said his sled does the same.... nothing to be concerned about.
I rode my buddies M8, super smooth and no clunk. Maybe it is just a Doo thing?

DOO thing for sure....My polaris is alot smoother on engagement. Doo's can be too with aftermarket parts.

Belt deflection and chain tension....assuming there are no wear issues.
Thanks everyone for the advice.
