So my buddy just bought a new shee. We are going through it all to clean it up. So far so good, very few issues. Anyway I'm a little confused with the set up. K&T head with 18cc domes, stock carbs, stock stroke, stock bore, stock crank.. Oh and CPI BB inframes. Stock timing plate with the holes egg shaped to advance the timimg !! It has 175 PSI in both cyl. 310 mains, 25 pilot. Plugs are black and wet. Original owner said he ran pump gas. Bought it out of Utah. Why in the hell would anyone do this?? Thanks for the input.
