are you getting a percentage on every jet sold by SBP?
i've never had to re-jet any of my stock carbs on any of the bikes i've built and run on Opti-2 (or any other oil, for that matter.)
not saying someone else might have to, but i think the majority can be tuned without worrying about re-jetting.
also, what might work in washington might not work in canada. just sayin'. with different elevations, humidity, etc, bikes will work different.
just find what works best for you...
