I have the only 4-stroke in my group of riders. My best Bud's have the following bikes: KX250- carbon tech reeds pro-circuit pipe, jetting. ; CR250 Pipe and jetting; KX100 pipe jetting, reeds (The guy that rides it is 5'1 and weighs 110lbs and a YZ250 bone stock-------- I got so sick of them all picking on my 4-Stroke .On the track I'm the second best rider, but that’s on just about any bike. So this weekend I called them all out- It's time to drag Race, I shut them all up after that, The only one I had trouble sometimes beating is the CR250, and that was depending on who got the best hole shot, My bike is bone stock and I weigh about 30lbs more then the next guy in line on size. I was just wondering if anyone else had to do the same to shut those 2-Smokers up!!
