Clunk noise when taking off from a stop

[mebearman]

2009 Polaris trail touring. After pulling up to a atop sign and then go to accelerate there is a clunk sound. If I coast up at don't brake I don't notice it. I think its from the chain case and I think I have that adjusted correctly. Is it normal with the perk reverse?

Thanks

possibly a keyway of some sort on the gear in chaincase? I dont know polaris. I know my old yamaha srx had a clunk in breaking. It was the key for the brake rotor on the top drive shaft behind the chain case.

side thrust on your secondary, no problem

What rp7x said ^ have the same thing. No issue.

Or older belt and it is the clearance on the primary you hear from a stop. When the moveable sheeve slaps the belt. Still, no issue

check that you haven't delaminated a section of the inside of the belt. Happened to me.

Agree, check the belt. I've heard/seen same type of issues on my buddy's 2005.

I HAD SAME THING ON my Yamaha. try different belt. Cheap fix.

I had the same thing on my ski doo. Older belt. If it bothers you change it or ride it till it brakes

On a Polaris sled with push button reverse that is normal. It is the secondary clutch,the rollers are floating between the forward and reverse tracks and when you stop and take off the rollers clunk into the forward tracks. Again this is normal

Thanks raceinsnow. That is what I thought was going on but wasn't sure. 1st time with the perk reverse but my son had one a few years ago and I thought his sled did the same thing.
