Clunk noise

[Moparluvr]

Hi. I have a 2015 Indy 800. It has a Indy specialties clutch setup, helix, weights and springs, primary and secondary. I noticed that when taking off sometimes it has a clunk, can feel it too. Is it just the Helix having play? Not sure what it can be. Everything is tight and driveshaft is greased etc. Stumped.

Ever had your clutches serviced?

I'd pull them out and clean them, check the rollers, springs, bushings, weights. Anything that looks suspect I'd replace.

Just all redone. Indy specialties kit.

Mine has a little clunk switching directions. I never really notice one taking off.

There is a little slop in the helix to go into reverse. Maybe you're just hearing it go back and forth?

Like stated above it could be your drive cogs in the track windows. they shift if you change directions or glide to a stop. Then have to shift back when you hit the throttle again.

It's the infamous Polaris clunk. Everyone that I've had over the past 25-30 years has done it. Sometimes it clunks when you take off and sometimes it doesn't.

Yep that's what it does, sometimes and sometimes not.
