I just purchased this quad about a month ago. I have changed out all the fluids and done most of the things any person should do when buying a new machine.

The guy who sold it to me, mentioned it had a Moose clutch in it. He claimed it would drag the hitch when he hammered on it. I tend to believe that at some point this was the case, as I put it to task immediately when I got it. The only problem is, I feel like I am launching the thing harder and harder and getting little to no hang time from the front tires. I pulled the clutch cover off and blasted the dust out of the clutch assembly with a compressor, it was pretty darn clean for a bike with 120hrs and 600 miles. The belt has about an inch of deflection in it, which seems a little high to me. It did not appear to be excessively worn, or damaged at all. The drive and driven clutch surfaces were smooth with no signs of wear. There was absolutely no sign of water or mud in the case. The clutch also engages at a rather high rpm for my liking, to be honest I don't even know what rpm but it's higher than it should be for the terrain I ride on.

I am not terribly concerned with top end since this is much more of a utility quad operated at low to mid range speeds. I like torque...a lot. With the current setup I stuck with my buddies brand new Kawi 750 Brute from a roll on. He got maybe half a bike on me. Out of the hole, he slaughtered me though. Partially because its a 750, partially because the SP is heavier and partly because the ***** made me line up in mud causing me to blow the tires off. Even with traction, it would not have been close.

I have 2 questions for my scenario:
1) How much deflection should be in the belt and should I replace it now while leaving the existing clutch in there?
2) Would it be worth getting the Heel Clicker kit and tinkering until I find the setup for me? I would also replace the belt if I did this.

 

1" of deflection is right on the money. Best thing to do with a belt is lay it next to a new one and you can see if its worn and how much.

 

Great idea. I have to get a spare anyway for it.

Has anyone done the helix upgrade with the HC clutch kit? Was it worth it?

 

I would recommend calling Rick Ritter. A contributor to the forum and he has helped me and lots of others. HE IS THE MAN! (Professional tuner)

there isnt much deflection in the belt. the belt also should set above the secondary(driven)clutch about 1/8" for the correct height. h/c kits are tuneable for take off,but i found trying them on a sp 450 and 800 that they arent worth the money. imo
