    how far and still run pump gas yami 1100

    Ok picked up a venture 1100 and trailer for 100 bucks.

    Have a line on a 85mm bore riva yamaha performance 5mm stroker. Sourced a set of gp1200 triple pipes and nice setbof 44 red tops.

    I take it im past the point of pump gas? Any way to retard timing to run pump gas and advance for race gas. Orl

    That all depends on the compression. You could run a stock head and be fine with pump gas. With the 1100 triple you will want to be around 145 psi for pump gas.

    So as long as i maintain that psi im good requardless of exhaust or carbs?. Am looking at 44's gp1200 tripples and protech 85mm superstock cylinders with billet head.

    The squish will also come into play but if you are 145psi or lower and have a reasonable amount of squish I don't see any reason you would need more octane.
