Ok, i have a Suzuki Fa-50, not the very best of mopeds, but the price was right.
First off, the damn thing tends to seize at high throttle, oil injector is functioning perfectly and the mix is correct, and the plug is the correct type and has the tan color indicated by good mixture - so why the hell is it seizing ? i've no clue...any suggestions would be welcome.
Second, anyone know where i can get parts or service manuals for this POS ? - one of the rings is cracked as it is, and i am out of spares - looks prettymuch identical to a Tomos piston, but you cannot 'eyeball' cylinder tolerances.
Third - fair warning, if you get a chance to buy an Fa-50..don't.
No force on earth can keep the exhaust system bolts from rattling loose after about 5-10 miles, not washers and not thread-loc, i am considering drilling them out and retapping them for SAE thread, which might help a little bit.
Takeoff accelleration sucks completely, due to the unusual snowmobile-type transmission mounted to this engine, however, the plus side of that is a high top speed - IF you can keep it from seizing up completely when it gets there.
The Suspension and Electricals suck as well (6V systems as a whole, generally do), and should you need parts - you are up the creek, it seems.
That being said - Also....
Have a friend that got a moped called a "Murray" - right now it's mostly in a box in his garage and he wants to restore it..by all that i can tell it's really a Puch Maxi, the engine is for sure...so anyone know where under that name it might have been sold ?
Guys got a bunch of stuff to build them with, mostly Califo and Rizzata <sp>? parts...any preferences or suggestions there ?
