I have been dying to do a build like this! Fantastic job on the scooter. It looks amazing.

AWESOME were you going to put the RAT I think you should brace the motor mount they might flex foward and backword........Curt

I still have alot of work to do on my motor mounts but my sprocket came in today so I can line it all up and weld up the mounts.Now i need the expansion chambe to get here so I can see how much room it takes up!

[slowriderz]

I got some work done today! I trimmed down the tank,cut and moved the petcock from the rear to the front,and patched the hole where cut it out. I think it looks a lot better this way. I put the sprocket on the wheel and im changing the motor mounts so it all jives together.The pipe came in and Im going to cut and reweld the flange so I can clock it where I want it,They come ran close to the motor for crank clearence but I want to run it out side the deck so ill cut it and make it work.

[FatBoy]

I welded up the motor mounts and I slotted the bottom plate so I can adjust the chain so I think im done for today!

[FatBoy]

I made a exhaust manifold so I can clock the expansion chamber where I want it,I think it should work allright....

this scooter just gets cooler and cooler.

Getting closer,I ran my cables and wires and finished the motor mount!

[FatBoy]

When I took it out for a test ride the tank leaked like crazy and the motor mount folded as soon as I popped the clutch!!!! I should have got some pics of the damage but I was irritated so I just tore it apart and fixed it.I made it like a I beam and test ran it without a tank and it runs good!!!Now Ill take it apart and clean and paint it while I wait for the new tank...

I kind of figured you would have trouble with the mount. Glad to see you got it fixed.I bet that is going to be AWESOME fun,maybe have to put a seat on for long distance..................Curt

Yeah I should have known better,I did not realize how much torque these little motors put out.I was kicking around the idea of converting it to a burrito stlye ride,but I think Id just build another one..

[FatBoy]

This after noon I figured I would get a little body work done....Since the fenders got dented and need a repaint I thought I would go ahead and add 8" to the front fender,make it match the rear ya know...I should have done this the first time!

[FatBoy]

I finished up the metal work on the fenders after work today ,I think the front looks right now its extended 8".
