Default Need crank extender

As some of you know- I have acquired a legendary and infamous a Kamasura 250 VRX.

The bicycle portion is a bland Chinese step-thru with a full-cover on the chain- keeping it nice and clean but a pain everytime the chain slips off the sprocket. And the bike is just plain ugly!

SO...a transplant is in order!

To show that I am fully and certifiably insane, I have already begun the transplant. Taking this hideous Chinese moped and removing the engine.

And transplanting it on a US made Dyno BMX bicycle!

I really need to find some way to extent the crankshaft out so it won't hang-up in the engine.

The big challenge is creating an extender from the crank to the pedal. The temptation is to just replace the really nice GT/Dyno crankset with a less substantial one. But I really like the beefy GT/Dyno set-up.

Note how the bike is alongside one of ScooterGuy's DiBlasi R7E motorscooters. Similar in size, but way lighter! I'll probably use this as my personal MotoBike- ideal for parks, and other events where the DiBlasi is too noisy. Of course, I have no idea how well this "Mosquito" engine will work- the connecting of the various mechanical bits is a challenge. I already plan on replacing the chessy gas tank with a classier looking teardrop one.
