I need to know the squish on a 2008 65SX. The tool to measure piston height is $65-$100. My son has just about out grown the bike and I don't want to spend that kinda money on something I'll use once. The gaskets that came with the kit will get me to .030-.033, squish. The other issue I'm having is starting. I have to give it a little carb cleaner to fire it cold....once running it seems OK. the plug looks slightly lean. This problem came about after changing the piston. I would like to make sure my height is good before any jetting changes. I also changed the reeds to Boysen at the same time the piston was replaced.
