does any one here have a cylinder base gasket they can measure for me?
I am working with a stage 5 slp system with 3000-6000 foot domes. usually I start out at less than 3000 feet so I think of lifting my cylinders a bit to gain cylinder head volume to ease off on race gas requirements. rarely do I get to 6000 feet high but I often start out at less than 3000'
50.5 cc chambers for 3000-6000 twin pipe
52cc chambers 0-3000 single pipe is what I see on the slp web site. so 85 mm bore add 3.5 thou gasket thickness could get me to 50.85 cc chamber volume. assuming 10 thou would add 1,4 cc volume, 5 thou could get me to 51.2cc volume.
what do you guys think of this calculation ? port timing would change minimally and compression would drop a bit, squish gap would be a bit more I want to be able to run pump 94 octane, possibly a touch of good gas when colder out or sustained low elevation running.
