Re: The boardtrack- bobber-bicycle looking thing...
Did a little work tonight.
This is ugly-
So I took it off for now so I have room to adjust the engine-
And since I only have bike tools and parts I did this-
But now I have to move the pedals-
And two final shots-

Re: The boardtrack- bobber-bicycle looking thing...
Today I got pillow bearings, a three foot 3/4" steel bar and some 3/4" (19mm) BMX bottom bracket parts.
I had some plate left over from another project and cut out a mount for the two pillow bearings. The pillow bearings hold a 3/4" shaft I cut down to 10". I got the bearing mount welded to the seat tube, so the jackshaft is now in. I need to buy one more pillow bearing tomorrow.
Since I hacked away my oil filler/check on the front of the motor, I needed to make a new one. I bought some brass pipe threaded on two ends, a 90* elbow and a brass cap. I also purchased a pipe thread tap so I can tap the block and put in a new filler/checker.
I also got my throttle lever welded on to the handlebar. I'm using an old Shimano 3-speed shifter flipped upside down and welded to the bar. It took some modifications to make it work. .
The shifter looked like this-
I have a lot of pictures. I will have to post them tomorrow.

Re: The boardtrack- bobber-bicycle looking thing...
Pictures from yesterday.
Here is the jackshaft mounting plate with one pillow bearing mounted. I made it with a cutoff wheel, drill and skate sharpener!
The new oil check/fill
Here's one of those "Hey Beau can you use this metal" moments. A piece of a store fixture happen to fit a euro BB quite well.
A trip to Fleet Farm (a.k.a. The Man's Mall) turned out to be really helpful.
I found collars that fit different size sheaves (pulley's) that had a 3/4" bore. I had to buy the collars and sheaves separate and will have to weld them together. The sheave slides on tightly to the collar too.
I stumbled upon 1/4" copper tubing in a 10' roll for a little over $5. It will fit 4mm or 5mm cable housing and I'm gonna use it to hide the throttle cable and brake cables.

Re: The boardtrack- bobber-bicycle looking thing...
I am jealous of you build. I have to ask, where did you find that motor? I have been scouring craigslist for that type of of thing for my current project but have come up short. Anyway good work I can't wait to see more.

I have the jack shaft mocked up now. I'm gonna need to gusset the mount a bit, but it should work good. I also need to shorten the jack shaft. Final word...It's not gonna pedal. I'm probably gonna have a tensioner pulley mounted on the chainstay too.
And the throttle lever-

I went to the steel yard today and picked up steel for the gas tank. I spent a good part of the night making a pattern and it's not the most fun thing I could be dong. I hope to have the pattern done tomorrow and the steel cut.
