He only thing I find questionable about the primary is the difference in the length of the collar they supply. I used (what I believe) is my OEM collar, because its longer. Not sure what the shorter one would do.
The collar would change the ratio of your clutches if using the same belt. If you install the shorter collar, you should in theory, have a higher starting ratio on your clutches. This is because the belt will ride higher in the primary. This could also potentially give you a higher top speed if your engine will rev out fast enough to move the clutches through full travel.
Try the shorter sleeve. It's not going hurt anything. If your worried about belt rubbing the case or screws hitting the cage, that would happen with the longer sleeve, not the shorter one. Installing the longer sleeve is like installing shims. It opens the primary sheaves more.
Ok got about 200km on the primary now. Started making some noise on my last ride. Pulled it apart to find the grease cover screws loose. Could have been my fault, fine. Took the grease cover off to find all the weights flat spotted again. I have no idea what the problem is. Guess I'll have to go grease less weights after all. No damage to anything else.
Thanks I'll have a look. This primary is supposed to have a 1 year warranty so I am waiting for a reply on the flattened weights.
As far as the grease cover goes, I had ot off, but I blame the thread strength more than how tight they were. I stripped one trying to tighten it, so I left it out.
The screws themselves should have had a washer, then lock washer. But the holes in the grease cap seem just a touch larger than the lock washer, so it sits a little crooked. I know there is lots of room now, so I will heli coil a steel thread in there and know I can get it tightened properly. Made in china I assume. Keep in mind, $100
Retailer told me it was a listing error and that the primary isnt even for my model. Well what a waste of time that was. They refunded my money though, so I am happy. I'll try some sliders in my original sheave now I suppose.
I just bought a 2002 Grizzly 660, bone stock besides some mudzillas that are stock sizing and and rad relocate. I’ve read all over that these bikes would hit 60+ no problem, but mine seems to limit out around 46 mph. It pulls hard up until about 43 then just seems to run out of speed, and sounds...

Well, my 05 660 just quit on me.
Was going downhill ish, just about at the rec limiter when the engine lost power.
Coasted to a stop at the trailer and she puttered to a stop, idled very poorly for a few seconds and then the engine died. Won't restart and feels like it has very low...
Well my 09 Grizz 550 went boom and the connecting rod blew thru two places in my cases. So I figured with how expensive it is to rebuild these when you need cases I mine as well go for a 700 engine. I looked around eBay and found a used suppose to be 09 Grizz 700 engine I'm not sure how to...
Ok, so I swapped the belt out after getting water in the case and shredding the old belt. The problem that I have came across it the primary clutch does not seem to be engaging until higher RPMs. I have lost about 15mph on the top end. It wasn’t like this before. I’m completely stumped and...
