Hey guys its been a while for me here on OldMiniBikes.
Anyways, took the bike out today for a bit. Was running fine and then it just started sputtering/misfiring under full load.
It didnt stall and I rode it about a quarter mile back home on maybe 1/3 throttle. I looked at the plug and it was a bit sooty, which I basically already knew that was going to be the case since I upgraded the jets to .036 and new emulsion tube without modding the air intake.
Changed the plug to a regular Bosch and took it for a ride.. Same symptoms.
Examined the spark and I thought it seemed weak. It was yellow colored and looked weak.
I thought I remember seeing that when these coils run on high speeds for extended periods, the coils just die faster?
I thought the spark should be a bright white/blueish color?
Did my coil just go bad like that in the middle of a ride?
