Yesterday I got out for a nice long ride on my 220. This is the first ride after replacing the fork springs (FRP .40) and completing the shim stack mod. Also I now have my jetting at the base-line specs that are reccomended on the JustKDX site. Wow! The difference in the front end is amazing! If you have not done this yet do it NOW! Engine performance is much improved as well. It will pull right from idle, making technical climbs MUCH easier. I was thinking of getting my carb and head modded my LRB Designs, but now I'm not sure if I need it.
