Stock motor, 92 octane clear gas with 40:1 Motul 800, VF2 reeds hi tension setting, PC2 pipe, 4000-5000 ft, 70 deg on up, I run 52/165
I intend to leave my main jetting at 165 but I may try a 50 pilot as it does run a bit rich.
I hope others chime in as well...
The four stroke engine: That's one stroke for producing power and three for wearing the engine out.
