On my Virginia Mapping trip, the chain, which was properly adjusted before I left, became so loose it started skipping over the sprocket teeth on acceleration. I'm fortunate that it did not come completely off.
I'm going to go with the same set from Procycle that I used before with the smaller front sprocket. See the parts tab.
The cam chain tensioner is leaking oil pretty badly. This is a common problem. According to some Youtube videos I watched, the old gasket can take quite some time to remove.
The timing cover port is completely seized. This is a common problem on these bikes. Procycle sells a billet replacement but getting the original factory plug out is proving to be quite challenging.
