I just want to leave my impression after an overhaul and all around mods on my 01 KDX220R.
First to make a short story, I purchase that bike slightly use and really clean last august.
The bike had all the original parts except for the back tire and a FMF desert pipe and a turbinecore 2 silencer.
The compression on the motor was still at 149 psi!!
When the winter came and after discovering this wonderful forum and the justkdx site, I have decide to do an overhaul and most of the mods I had found on both place.
The bike end up with these mods: New Wiseco piston, Boyesen reed, R&B carb and head mod, fix a dent and clean the pipe, Air box mod, replace rear shock oil, did the 2 shim fork mod put FRP 0.38 spring fork and 7.5 oil at 90mm.
I just have finish to fine tune the jetting at 68°F, 1000Ft elevation and end up with a 155 main, CEK needle fourth clip from top and 42 pilot.
The result is just fantastic compare to the bike last year.
It pulls a LOT more from bottom to top and the throttle is really crisp. The fork mod is a huge improvement over original (Now I am riding at speed that I would have hurt myself last year).
So for the riding that I do (tight wood trail mostly 1st to 4th gear) the bike is just perfect.
I really enjoy it now.
I want to thanks all of you that have leaved some input that have help me with my project. Hope you will enjoy the summer as I do… :cool:
