Good News: Electrical system is pretty much done and this DC converter works.
Bad News: Was having some chain tension issues, mostly caused by the bushing that was mounted to one of the polycarbonate plates. I relocated it to an aluminum side plate, and will need to cut a longer axle.

I should be able to go for a test ride tomorrow.

The 30amp drive and 5amp ignition fuse holders are located on the tank underneath the seat.

It's awesome!

Damn. That looks good.

I want it.

Rear Chain tensioner.

Good News: Motor outputs a good amount of torque

Bad News: It outputs enough torque to sheer set screws.

I'm going to have to make a new freewheel thread adapter out of steel so that I can weld it onto the chain axle. The aluminum one is pretty much destroyed.

Setbacks: LOL.

Good to know that it's going to work out though... would hate to see that much planning and execution go to the scrap yard because of a few screws or something.

Teaspoon of Personal Opinion: Seat could stand to be MUCH lower... suspension could probably be lowered a bit, as well.

Well, at least it's got a lot of torque...heh, and at least you're getting the kinks worked out ahead of time. Better now, in a parking lot or home or w/e than down the road, when you least expect it.

What were the specs on the motor you used again? I misplaced them somewhere.

Also - is that an automatic chain tensioner, or set and lock?

I've estimated that it's spinning at 4200 RPM @ 60 volts.

The chain tensioner also acts as an axle spacer and adjusts with a spring.

Brake light and turn signal LED array is together and works.

However it's way too bright, so I will need to add a diffusor to it.
