I believe I have found the issue as the front piston has a taller stroke then the back (minimal but makes a compression difference). Everything has been torqued to specs and the motor runs perfectly fine. can i just put in a smaller dome to bump up the compression?

this seems like the easiest option first

when doing a leak test do i seal off all the water line ports as well or just the exhaust and intake ports?

how do I do a leak test? I also read somewhere that the 64x motors have a weird timing or something is there any truth behind that?

it was bored and honed, and I have new pistons and rings I even swapped domes on the cylinders thinking they were miss labeled and same outcome.

A ski i bought the guy said it was a 760 and that all the info he gave me. I honed the cylinders to 84.5 no porting (stupid me) and a new ADA Head with 38cc domes. I found the motor was a 64x and I still have different compression in each cylinder. The front seems to be at the correct...

I Bought a new Ski last year and it came with 64x cylinder. Through out the year I have replaced the head and added 38cc domes bored and honed .5 over so new pistons and rings. and re jetted carbs. When I first put it all together I was blowing around 175 in the front and 150 in the back. I...

Has anyone seen or bought this CDI off of Amazon? https://www.amazon.com/Yamaha-Adjustable-Limiter-Blaster-Venture/dp/B00R5623W0

yes i still have them. i have the manifold and stock reed cages as well.

i have oem duel 44 with mani and reed cages. carbs have the easy adjust T handles. PM me if you are still interested

Updated and lowered

i used to use a hitch hauler and a beach tote

Greater Performance Girdled head. Came off a running 760. I don’t know any history of these or what size domes are on it. Could use some cleaning up. $80 plus shipping

Don’t the 760 64x usually run different compression originally. I remember reading that somewhere. Or was that just based on tHe stock head?

How do I measure the domes?
