I pulled the clone engine,a Hawg-Ty off of my modified Hiawatha mini and installed a new Greyhound 6.5 with the lighting coils I installed.
The engine was just tall enough that the fuel tank would not fit in the frame and have the gas cap reachable.
I replaced the tank with a Brigs&Stratton tank and it fit OK.
I took off the engine governor and set the max RPM via the throttle stop to prevent engine over-run and possible damage to the fly wheel.
My first run to say the least was scary. This little bike was so much faster than the old engine that great care is needed if you crank the throttle open and the front wheel is slightly turned.
Wheelies can be a problem on pavement if I don't take care. On my dirt road spinning the rear tire is an issue with loss of traction in a corner if I goose it.
The bike only has one brake,a drum / band at the rear. It is original to the bike and the band material is pretty much worn from age and use. Before I go crazy on the paved roads I really do need to replace it.
I'm not complaining, it is just a different beast with the engine swap.
I have no idea what the top speed will be but it is much faster than the old governed 30 MPH on paved roads. With a billet flywheel I may try it some day.
I got to drive a "Popper" bike while at a rally in CA a few years back and that was what a ride to be sure. While nothing like
a Popper bike my little mini is a hand full if your not expecting it.
I'm sure the clutch will have a short life if I don't keep the acceleration down to normal while putting around my mountain.
