I have the same with timing adjusted to +4 with VF3's, Boss Intakes, Stock Carbs, T5's & still run pump gas..
I might mix a bit of C12 with it every now and then

Timing and compression ratio dictate how far you can go with pump gas.
I'd say 140ish on compression and +4 on timing should be fine on pump gas.

Pipes, open airbox or remove the airbox, mill .015 or .020 off the head, bump the timing up, rejet. If you're not riding TIGHT, technical trails....shave/lighten the flywheel....
