topspeed

Hey My bike seems to top out at maybe 70. I was going up a mountain pass and my bike started acting funny today and totally slowed down hasn't happened before but I have only ridden the pass once before. Any suggestions of things to tweak or replace will be greatly appreciated.

I was just interested to see what speeds you have got upto ? I know it isnt at all designed for speed but i was just curious! And is there any mods you can do to increase acceleration and gain speed thanks :).
