Found at the Mid Ohio AHRMA event in July 2005, when I purchased it the seller said
he had found the bike, changed the oil and found the on/off valve to the fuel tank to
leak.So instead of putting fuel into the tank he took a soda cap and filled it with gas. He
said with two kicks this little 4 stroke fired. I looked at him like he was crazy and out
came his soda cap, to prove his story. I bought it on the spot.

The motor is a 123.175cc 4 stroke, 53mm bore and 58mm stroke with a 9:8.1
compression and 12 HP.  The 20mm SSI Dellorto helps to push this 206 pound bike to
(The handbook says, I am not that crazy) 70mph and is capable of 87mpg.
