May have a problem with my jbs clutch kit

If that were true then my buddies wheelers that I raced with the other weekend are incorrect as well. And they both have stock tires. Plus I was able to hit the 65-68 mark with these same tires before the Install. So something has to be going on here. I don't know what the rpms are for sure but they are way up there, don't think I've hit the Rev limiter, but it's close.

what weight did you get

Lol, not sure, the tan of ones. They were the ones sent in the kit.

So I watched a video of a guy with 28 inch tires, easily do wheelies and claimed a very noticeable difference. I don't feel much if any difference in my jbs clutch kit and lost about 10 to 15 miles per hour. The kit came with a milled sheave, slugs, weights, don't know what gram they are, 16 or 18 grams I think, and a dark gold spring. The guy in the video mixed weights up to get a total of around 120 grams, about a 1mm shimming, and a purple spring. So I'm pretty sure I'm running quite a bit heavier weights and a different spring than him wondering if maybe I should try lighter weights and the purple spring, what you guys think?

After watch your video I would say you have way to much grease in the sheave. Your secondary may as well!

^^^X2^^^ Never have taken any of my cam plates off and have had all the weight stuck to it. I did a quick search and top-end, hitting rev limiter on the stock 700 Griz looks to be around 64-65 mph, even when running 104 km/h. With big heavy 28" tires and a stock engine I would bet your top-end would be reduced considerably.

My big tires are not my top speed problem, I was able to hit as fast as 70 and 71 with these tires before I did any mods at all after this clutch kit was when I experienced a loss of roughly ten or so miles per hour. It is possible I still have too much grease in that clutch with the weights but based on several other videos I looked at it seems about right but again that could be my problem. I'm hearing a lot about lighter weights and the purple spring. How would that combination affect me?

I greased the cr4p outta mine and I have no problem.

I blame Rob and James for making me need new tires & safety harnesses.
