KDX200fromAUS

Hi, yeh my 91 200 has been resleeved before i bought it, it had a 66.5???mm piston but no compression, so i purchased a wiseco 67mm to suit and rings and done it myself, just got the bore honed to fit first. I have two sizes left before another resleeve.

Also replaced all the powervalve setup, all but the activator shaft were snapped. Crank seals, countershaft seals, all the swingarm etc. And man is this thing a weapon, I absolutely love it now.....if anyone out there thinks yours is a bit lacking, check the powervalves and top end, freshen em up and hold on.


One thing to add, through experience with with wiseco in the past, MAKE SURE YOU RUN THE BIKE IN FOR A GOOD HALF HOUR at least, avoid lots of throttle for long periods of time, especially in high gears, generally stay in around 2nd- 3rd, just on and off the throttle , run the bike with plenty of oil in the pre-mix for the first tank too. Wiseco will nip up if you dont treat them right.

Any more questions ? just ask mate....good luck

Yes, smaller carb is fitted.

Pipe mountings are different, I purchased an FMF pipe and it has lugs for springs but no bolt holes, so just made a flange to bolt to engine and drilled holes in it to add springs aswell.

Basically just measure your cylinder and find a piston that will fit it after a hone, the difference in price couldnt be too much anyways.
