I took my cousin to get a safety cert. so he could ride a silver lake. Took it through MATAVA. I kept talking to the guy asking if I could ride a little as possible, I was worried about overheating. I'm piped, 19cc domes Vforce2s 38mm carbs, Grand River port job, lockup clutch 16/41 gearing on 22 in. trail tires running c12. He kept talking crap about everyone who takes the class with a banshee with pipes thinks its a super bike and all that stuff. So we took a little break in the training and he asked me if he could ride my bike, I said sure no problem he takes of across the field on the rear tires and hits a couple of hills with some great air and comes back on the two right side tires with the left ones in the air just balancing perfect. He gets off and says nice bike runs like my Duncan ported machine, hang out and later will hit the moguls on the other side of the woods. Needless to say I had fun at rider training, did learn some interesting facts about the atv laws, and some riding tips.
