Re: MBA Motors Mortorized Mountain Bike Anyone?? HELP??? HELP.....
When reading the beginning of this thread, thought - electric start, need one of them!!
I have at least 6 of then! lol When putting my first friction drive bike together in 2008, was adjusting the carb and idle speed. The heavy starter wire hit the frame, thought someone was welding in my face. No battery in the bike or anywhere near. They charge big time. You may need a rectifier or some such thing.
That is one "Swell Elagant Machine"!! Hang on to that baby, or sell it to me!! lol.
It looks like a belt drive reduction box under the metal cover in the pics, will look again.
The Titan 50cc 4 stroke should bolt up to the box and many other engines with the 76/78mm centrifical clutch. Mite need a longer belt to the rear axle if the motor sits higher.
Try a new plug? That same physical size motor comes in 49cc around $100. The Harbor Freight 52cc water pump and auger motor is the same size will bolt up nicely.
If there is room to put a larger pulley in the bottom of the tranny or bigger on the rear wheel axle that will help. That must have been a very costly machine when new.
The Hf 52cc would be a big improvement and would be a simple switch.
Not sure about the starter, and they can be a bear to remove. A friend has a HF 52cc on a cvt and now a friction drive, near 2 yrs now and loves it. Pd around $100 on sale with a extra coupon.
