I was browsing the FMF site and I came across thier jetting chart. for my '90, they recommend 170 main, 62 pilot, middle clip stock needle. This is with 32:1, 50/50 mix of race/pump gas, at sea level. I thought that it was kinda rich for the pilot so, I checked the '04 jetting, they recommend 168-165 main, 52 pilot
Turns out they recommend a bit different jetting for each yaer?? What gives, I thought the kx5 has been the same since 89? (at least when the engine/carb is concerned) Did they change port timing, or carb slides at some point??
