Well I finally got it up and running but, boy what a mess. I have a nineteen nighties something Giant Frame with a Trek 700c fork and a new Skyhawk 66cc engine.
I set up the bike with a Kings adapter so I could use a disk brake rear hub and have a bit more "gear" for speed. I have a 36 tooth sprocket and it does seem to go at a good clip. I wound up paying more for the rear wheel than I did for the motor.
To push that gear I installed a "tuned" pipe from Sick Bike Parts and that made my little bike really go! (I modified that pipe to it did not hit the crank and I set it up so the smoke would go away from the rear wheel. I did this by adding four inches to the end of the pipe and then when I replaced the silencer I put it at a five degree angel)
The Giant mountain bike frame had a seat tube that was way to big to fit the mounts that came with the kit, so I made my own. and that would have worked OK but I got tired of having my pulleys disintegrate as well as all the spokes on the engine side of my wheel.( I build wheels and have a full bike shop at my home including frame jig and torch) So since I have vertical drop outs I thought I could move the motor forward to tighten the chain. Guess what the mounts broke.
Now I have a good excuse to change the frame a bit so I replaced the rear dropouts with track type and I welded a derailleur hanger off the pedal side
So the next thing I did was to pullout my spare engine that I kept just incase. I only used the motor and the CDI that came with the kit. I got it all hooked up and nothing... NOW WHAT?
OK so I replaced the spark plug and shielded wire with the one that came in the kit and the cheep plastic boot broke, Arrrg!
Next, I went to the auto parts store and got a new spark plug wire installed it and nothing. So I looked at the sight here and one guy had magneto problems so I swapped magnetos with one of my old ones that worked and nothing.
Finally I swapped out the NEW CDI that came with the kit for the old one that I had. The problem with the old kit was that the connecters were damaged and so all I could do was to strip the wires and wrap them around the new connectors. and then it took right off.
I got about two miles before the connections rattled loose and had to pedal it home to strip and solder the wires correctly.
Once again It takes right off I go around the block and park it in the garage only to come back to see a pool of gas below the bike. Turns out that my old carburetors shut off valve is not working so after I tear it apart and unsuccessfully try to fix it I replace it with the new one.
I think I have everything working the way I want now and if I can keep things going until I brake this one in I am hoping to get quite a few miles out of this one.
