New rider with custom chop

lopee · #1 01-27-2010, 05:14 PM

Hello All,
Im new to the forum and am starting to build a custom street tracker style motorized bicycle. I will be building the frame from other frames and tube steel. I plan on using an old 49cc wing-ding with a jackshaft to an eight speed rear cassette. Im in the process of building an inverted springer from an old chopper style triple tree fork. I'll be running duel disk brakes so the jackshaft will be mandatory. The bike is going to be full suspension using a custom rear swinger, shock undecided. Probably will be customizing a fuel tank and fab up a seat pan with a fiberglass tail. This is going to take a while, 6 months or more. Pictures will come as my progress builds. I have some ideas im sure i will need help with and have a fair amount of skill to offer others on the forum. Im also a professional bicycle mechanic with over 10 years of experience.
I have a questions for now as I plan it out.

Can i get a larger cylinder and piston kit to move up the size from 49cc to 80cc or just buy a larger engine?
Thanks, Jon (LOPEE)

Sounds like a sweet idea. One note: Consider using a 7-speed setup. The reason I say this is that an 8-speed sprocket set uses a thinner (read: "weaker") Drive chain. Also, 8 gears, while sounding cooler than 7 is somewhat excessive, and probably wont give you much more driveability. At least not enough to justify the extra shifting. But hey, I might have no idea what I'm talking about. But i do know about the chain gauge thing for sure.

So ive been sketching out the design and working on the forks. My camera batteries just died, so ill post a pic of how the forks are coming along later tonight. Here is a sketch of what it should look like. Im still toying with the idea of using and old cruiser frame so it blends board track and street track.

So iv gotten some work done on the springer. Still needs to have the plate where the springs rest welded up, but over all seem like its going to work well. Then ill be doing some cosmetic refining to make it looked more machined, kind of rat right now but will be just peachy when done.
