I just put new piston,crank bearings, cylinder replayed. Went through carb set float level with a guage to 7.5mm, 400main, 55 pilot. Did leak down test and doesn't seem to be leaking. Gas flows freely from peacock. It feels like its starving for fuel. I bought the bike seized up so don't know how it ran before. I'm at my wits end. Any ideas?
