I just built my first go kart. I put a 8hp diesel on it with a 30 sieres torque converter. It has a 10 tooth with a 80 tooth. It's a two person smaller yerf dog so some times I have 300 pounds in the cart. I have the cover on for the cvt but I noticed that along the engine there is very small pieces of the belt. I was wondering if this is normal. Also I was gonna change the cvt spring to the 1st hole but since it's a diesel it red lines at 3600 rpm so I was worried I wouldn't get much speed, but I really don't know how that system works. Thanks for your help
