On a snowmobile yes, on a drag atv no. You should swap that clutch to a Polaris P2 button clutch. The rapid reaction clutch provides quick shifting both up and down, you don't care how fast it downshifts.

Your primary clutch is fine, no need to replace that.

You want to try a clutch like this....

Now that I think about it though, the jackshaft your secondary is on is splined rather than keyed? The links I just posted are for a keyed jackshaft, not splined. I'm curious to see what Madcow says about using a rapid reaction for an atv drag racing application.

You might want to go to a P-90 primary clutch off of a Poalris ATV. The P-90's have cooling fins on the backside that act like a fan for a little added cooling.

Secondarys They should all be the same size if they are keyed.

You want a button type secondary off of an older (90's) polaris. Then to get the best performance out of it you will need to take it all apart, rebuild it with new bushings and some SLP hyperslick (or something like that, can't remember the name) buttons and a new helix and spring.

Ebay or any snowmobiling forum. Hold off to sell it until later this fall or winter, you'll be able to sell it for more money and with less hassle.

oh yeah I forgot to ask on these polaris 800 is there a rev box. All That I have on the bike is the cdi. I just wanted to know if I could turn some rpms. I pretty sure my power cure has went up from stock. Iam just wondering what rpm I should run at, and take off at. The engine has been bored .30, drag ported poilshed, high compression pistons, fuel is alky. I think Iam right from what I have read stock thay turn around 8500 rpms. Just wondering if the cdi controled the rpms or thay have a rev limiter.

No rev limiter, this is why you can never run the engine without a clutch on it. Without a clutch the engine will over rev and most likely damage itself.

For the clutches you posted, I'd go with one like the second link.

I wonder if it is a big enough helix. madcow said I needed a big helix. If it would work without having to buy a new helix, I would go with that one. what do you think about the rpms. where should I try to keep them 9500, 10000. I was thinking about having it launch around 5-6k rpms.

RPMs depend on the engine work and pipe(s) did you get any specs with the engine or who built it?

You did the porting as well then? Can you call the place in florida and ask them what RPM the pipes are meant to be run at?

Port timing, pipe design, pipe diameter and pipe outlet diameter all factor in to how well your engine is going to run at what RPM. In order to do things right you're going to want to save your pennies and find a good dyno that you can put your engine on.

Here's the buttons I mentions, SLP Super Slippery Buttons

Ya it's gonna be tough to find one in Tenne, but if you want to know when to put your power down it'll be worth the money. You may even want to look into shipping you engine and pipes off to Larry Rugland in WI if you can't find anyone near by.

i hate the small atv button secondarys.

what diameter is the secondary clutch you have?

for drags the roller clutchs can work good, for speed running they are very hard to use because they want to backshift instead of holding.
