Alright all you thumpers out there. Here is the big question? Right now I have a 2000 kdx200 with all the mods except head work and boring it out. I`m 6` #210 I had to redo the front fork because it`s set up for a #130 rider.First dirt bike I have had and love riding tight trails. Now I want a thumper. looking at a 2002 wr250f is this a good move or not? Don`t think I`m ready for a 426 yet, so don`t even think about it. The only thing a hear about the Yam 4stroke is the hard starting is it true or is it BS. Help me get out of the KDX forums and into the thumper forums.
