It great to hear you got it going! All of that wrenching also gave you lots of hands on with this bike too. You know the bike inside and out now!

Yes, I have gotten to know this bike far more than I expected, but that is a good thing.
Your posts (and a couple others) have been extremely helpful and appreciated.
I will certainly check out the motor resource. Thank you.
When reassembling the motor, the trickiest part for me was getting the cam chain back on and with the correct timing. It took a few tries, but I got it. One attached photo shows the position the other shows the intake valve where it was hitting the piston and is definitely bent. My timing may look a little off, but it is just my angle with the phone.
I believe the timing was off on the original motor. The ticking noise I heard, and thought was just the valve train, was most likely the piston hitting the valve. That noise is gone now and the motor is actually pretty quiet.
Hopefully going for a test run tomorrow. It has been raining here for a week...
