Well ... we got trouble in paradise guys. I've been howling about the cheap 8mm chain but the real problem is a cock-eyed motor mount. The crankshaft isn't perpendicular to the frame. That ain't gonna work!
I have any number of excuses for this and here's one.
Look at this itty bitty sprocket.

How do ya put a straight edge on that little bugger?
Another thing that led me down the path is the motor's overall length. I can barely get an air cleaner on between the seat post and carb, and meanwhile out front the pipe wants to run into the downtube. That's where the current configuration pretty much needs to be and I thought it was straight.
But, with failure, always comes the opportunity for improvement! And that's a good thing cuz I fail a lot!
Since I started this endeavour I've learned the pocket bike guys get these little motors all wound up with pumper carbs. Which are a lot shorter than that Mikuni I put on there years ago. That'll let me move the motor back at least an inch and probably allow for some amount of offset to get the primary chain tucked in a little tighter too. What we have here is an opportunity to "Refine the Design!"
I'm also gonna gut my spare motor out for mock up. A long bar thru the crankshaft holes will tell the perpendicularity tale. I'll get it straight this time.
So ... I thought I was at the beginning of the end. Turns out I'm back to Square One! Mounting the motor was the 1st thing I did.
