well ive had alot of trouble with top speed with my dtr 125 2001. basicaly it seems to accelerate like a beast, yet once it hits about 60mph, it has nothing left, so i removed the 'reed switch' and it stays the same speed, but the revs keep climbing, surely this cant be right :S?(was thinkin maybe the speedo cable wasnt put back on right, but it went on the way it came off :S) ive got standard exahuast, but im pretty sure its not that restricting. any help please because i cant find anything anywhere haha. i just find the same old stuff, which doesnt ever help, and its got a recently rebuilt engine which was run in fine.

Same speed but increasing revs = Clutch slip, you may need a new clutch plate set.
