Hello,

Stock engine, stock bore, Supertrapp II exhaust with no discs (completely open). What would be a fair starting point for a jet? I'm running 145/42.5 and it sounds like it's running okay. My neighbors don't appreciate the sound as much as I do around here so I'm planning a ride in a few weeks and don't want to cook up the motor. Would 145/42.5 be too lean? I have a jet kit for a 150/45 I can install. The machine starts and runs really well for the minimal riding I did but occasionally on WOT it dies out but im unsure if the engine just isnt warmed up yet.

Thanks,
Michael
 
I would put the 150 main and 45 pilot in and see how it runs.
