I was riding bmx at my trails last night when i heard a 4 stroke pull up on our little 50 track at the bottom of the hill. Ironically enough it was a vet rider I used to race mx with in the mid 90's. He had an older xr 200 and was cutting a few laps. I went down, talked to him for a minute and he asked if I still had a bike. I laughed and told him i'd be back in a minute. Needless to say when i came back he had no idea what to think of my 50. We rode for about 15 laps and it was a dead heat. The power to weight ratio kept me either right in front of him or glued to the back. ALL I got is a TB kit with a stock head too. I rest assured a 50 with a head would crush an xr 200 cause they don't have enough power for thier weight.
whats the weight difference on a xr100 and a xr200? my xr100 in a straight line will kill a xr50 with a powroll 81 kit, ported stock head, powroll cam, and fmf powercore 4 pipe. all my 100 has is a big gun pipe.
