I could not believe the difference in power and when I took airlifter off to put in after run oil, I noticed that throttle only opening 65-75% Max. So more surprises in stock for me next run….95% throttle


Down side is the 359 on road crab would cost more than engine + pipe put together.
itried a ws73 carb on my 08 version and was not impressed. it runs great with the go carb and has better run times too. i must have lucked out cause you are not the first to have carb issues with the go's. i love them tho, jp-4 with long nova header, woohoo!!
