Ok, so I recently just rebuilt my engine with a 70 over bore with Wiseco piston. I also have a D&G pipe, 1/2" reed spacer, stock carb, and custom open air box. No clue what size jet is currently in, but what is suggested?
What Size Jet?

To be safe, I would start on the fat side and work your way down. Mix your gas 32:1, and put a 290 main jet in it. See how it reacts to that. (Spark plugs are cheaper than rebuilds!)
it will all be trial and error, but like said above go larger first. whatever you do dont pay a shop to do it. that cost too much.
