Hi everyone, so glad i found this forum.
I ride a 06 XTR, it has micron pipes and dna filter on, but still i need more speed.

I had her on a track last week, and the only problem i had (besides the foot pegs grinding on the road) was the top end at about 185 km/h (that is about 115mp/h)I need to replace the chain and sprockets, so i was thinking of going 3 teeth smaller at the back. will this make a big difference?

Oh yes, and I worry about riding the xt to hard keeping up with the sports bikes.
How tough is this engines?

Thanks for reading
