Re: Greetings from the middle of nowhere.
Looks to me like you're approaching this build in the right way, seeing to it that the bike is safe and roadworthy before the engine ever gets mounted. The drive system you've chosen is I think a good choice. I'm thinking about it for a build I want to do later this summer so will be following your progress with close attention. I'll be interested to hear how you like running it. From all that I can tell it appears to be a reliable engine and drive system. Thanks for sharing and keep those pictures coming...
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
