Grabbed a roketa 200cc (possibly 250) for$40.
Its been beat to hell. I changed the oil today. Black and gritty. Overfilled it with rotell 15/40, drained again. I use a paint screen when i do a oil change on a new to me bike.
It had slivers of alum, and specs of black plastic. Filled it to the spec level
Then i pulled the spark plug. And looks like it was running very well. A bit of fluffy black on the the threads, dark tan on the porcalain. A tad rich, but id ratherrather that than lean.
Figured out wich way is run on the kill swich, and placed the plug grounded to the fins. Kicked it with my hand and got a blue spark. Not brite but blue wich is good. Yellow spark is weak.
I have one of those cameras u can stick in holes. I stuck it in th spark plug hole. Not alot of carbon, piston looks good. Thats all for now. I just dumped 4 qrts of oil in my garage. Toutles!!!
