Re: what did you do to your motorized bicycle today?
I've been slowly, slowly leaning mine out. I was satisfied with the jetting til I took a look at the piston through the sparker hole and saw a bunch of coal in there.
I don't want to risk it seizing but I do want it to run right and not get all munged up.
I start it up and let it idle for a couple minutes, then run it at haff throttle for about 2 miles, then it's off to the races for the rest of the ride.
I give it 20 minutes to cool off then read the plug and look at the piston.
Gotta go, the 20 minutes is up..
