I've rid'n 2 years on my 2003 220. I ride about 5 enduros and 5 dual sports each year along with some misc trail riding. I've been thinking about moving towards a KTM 250 EXC to get better suspension and higher quality components all around. However, thats probably a $4500 upgrade after selling the KDX.
Has anyone upgraded the 220 with Fredettes cylinder porting, head mod and carb bore? How about a shock re-valve? I'd be willing to try those if it will add significant performance. I'm also wodering if my fixation on the KTM is one of those "the grass is always greener" things, not sure.
