Loud clunk on acceleration an deceleration 2003 700
Got a pretty loud cluck coming from maybe the transmission (but not sure) on acceleration and deceleration. Only clunks once while accelerating hard and as soon as I hear it I let off and it clunks again on the deceleration. Keep in mine this atv has a turbo and seems the clunk happens about the time I build some boost and put strain on the driveline. Thinking maybe silent chain in the transmission but wanted to get your guys opinions before tearing it down.

It's always had the polaris clunk from day one when I bought it new. It put in all new u joints from front to back less than 100 miles ago. Spline yoke has also been loose from day one. This is a hard cluck while accelerating around 35mph or faster when building boost and putting a strain on the drive line. I have the transmission out. I will report back with what I find in a couple days when I have time to tear it down.

I hope that is what the clunk is from. The chain touches the case on each side if I move it over with my finger. I don't see any marks on the case but it can't be far off from rubbing it. I will report back if the chain fixes it.

Hope its all it was
