I was out for a ride the other day on my 10 renegade 800 I have qsc primary stock secondary 29.5 OL2 and we hit a stretch of rode and driving in high about 60km/h or 35mph once I stopped the belt started smoking out of the snorkel. I am guessing this is largely to do with the size of tires and the speed I was going but can I do anything clutching wise to stop that from happening? Would a stm secondary help? Any suggestions are greatly appreciated thanks.

i'll start out with the obvious, the belt smokes when it is slipping. the belt could have been wet, have bad deflection, been previously glazed over or just in bad shape altogether.
one way to avoid smoking your belt under normal driving circumstances is to try pressure the primary's sheaves a little quicker by accelerating a touch faster than you normally would.
depending on how bad you smoked it your belt could be junk but i've gotten away with lightly scuffing mine with an sos pad.

Either that or he just needs some fine tuning on the clutching

you might have smoked it by using high when you should have been in low when driving in the past...

Lots of guys on here just running QSC primary with stock secondary. As a check, I would take the belt cover off and look at your alignment between the primary and secondary. Crank it up and bring it up to 6,000 RMP's or so in neutral and back down to idle several times to make sure the belt is riding between the clutches smoothly and looks aligned correctly. Also, check the belt to see how it is wearing, if one side or the other is more worn than the other, may mean something is out of alignment. Also, may have a lot of belt dust (assuming you cleaned when you installed QSC clutch) if your belt is wearing prematurely. I don't think QSC recommends an adjustment to stock secondary, but you can call them to ask for sure, or someone else may know.

I agree with Rzrback. I run QSC and stock secondary setup with a Gates belt and have yet to spin it.

Make sure your cvt intake and exhaust are not plugged. That's the only thing that comes to mind why blowing a belt at high speed. Could of just overheated because of bad air flow.

How long ago did you get your primary? There are now 2 sets of weight options for them as well. One works best with big tires and primarily low gear. The other gives up a little of the low gear performance and lets you run in high gear a little more freely. It's very important to speak to someone when ordering so we can get you set up properly the first time. Gets expensive and time consuming to be changing parts and having to go in and mess with things repeatedly.

Did you snorkel the bike? If so, do your snorkels have screens? If they do, cut them out.

I had them in mine. Someone told me that was why mine was running so hot (I actually melted a belt when racing another guy on the backside of Windrock. Long ways from the truck, not good.) Checked them, sure enough they were clogged. Cleaned. Checked again 5min later they were clogged again. Took my pocket knife to them and cut those darn screens out.

No more problems.
