OK Sorry for not updating sooner. The motor is in and running great. Quieter than the 90 and shifts nice and smooth. Installed a shifter pivot which I'm sure contributes to the solid feel going through gears. I checked cylinder compression on the 99 got an average of 220 psi.cold. Low was around 210. The old motor averaged around 170 psi. I do notice a bit more get up and go.
Running short trips right now to feel it out. We have a camping trip to Knoebles Amusement Park in August towing the camper. A West Virginia trip and I might ride the bike down to Ocean City Md. in July. We'll see how it runs in the upcoming weeks. I really hope this is the first and last major repair. I'd like to think this one will last my lifetime. Next project, go darkside.
