Did Honda make any mechanical changes in the 300ex through the years? Just wondering if they tweaked anything important (besides the color of the plastic).

Thanks.

 

the only changes were colors of platics and stockers.thats it.

 

I think there was a change in the engine after the first year (1993) because I was looking for a cam-chain for my 97, and the part number for myn only fit 94-02, 93 had a different part number. 93 has a different engine than other years???
