I think the reason most people are having problems is because their not being realistic about their engines performance state.
Unmodified, or slightly modified should probably try #5 (per Procom), and modified mildly should try #6.
I believe most are over rating their performance mod's, and think a higher number will BE a performance gain, which it WILL NOT!
Mine has modified intake, exhaust, gearing, and jetting. BUT NO INTERNAL ENGINE MOD'S !
I set mine on #6, and there were NO hard starts, or ANY OTHER ISSUES!
It was like the stock units as far as reliability and starting, idling, etc. Just the higher rev. limit setting.
IF ANYTHING, I kinda want to back it down to #5 to see what happens, but since it acts so perfectly as is, I never remember to change it, until I'm at this keyboard.
Be REALISTIC about your performance upgrades, and IF you haven't gone inside the motor, try #6. (or 5).
