I had a cracked cylinder so I decided to go with a new big bore kit from cylinder works. I had a friend who is mechanically inclined come over and help me install the kit. We did everything according to the Yamaha book. Doing the timing chain was a pain. I got it all buttoned up and went outside to kick it. It has WAY too much compression. Even when I pulled the spark plug out it is kicking over too hard. While we had the cylinder head off the piston traveled up and down the stroke very nicely, wiping the excess oil off as it was supposed to, so I know the piston is in correctly. The cam assembly isn't rocket science, and it was not my first 4 stroke top end rebuild, and about the 50th that Erik has done. But something is wrong. Why is there so much compression? I did not kick it too many times, and I did NOT kick it hard, just moved the piston up and down a few times and realized there was a problem. What should I check first? Could the cam chain adjuster be too tight? Where do I start? Thanks for the help!
