Ok so to start off the bike hasent been run for about 2 years. It lost compression once and I had the head, valves, springs, all redone because the valve seats were bad and not sealing. I rode the bike about 3 times and one day it wouldnt start again (no compression again.) I checked the valve clearance and it was good. I ended up getting an 07 and the 04 has sat since. Well this past week i bought a new piston and installed it in the 04 thinking maybe the piston was bad. I had the cylinder honed and everything put back together. The bike still has no compression. I checked all the gaskets and they are good. Any other ideas?
