Hello.
I think my YFZR has a to weak ignition because the spark plug is totally black, and i can se the piston is a little wet. Now i have measured my ignition coil on the secondary side, and it says 20,2k ohm(20.200 ohm).

The manual says it has to be from 8,64-12,96k ohm. So I would say there´s to much resistance in the coil, but maybe I´m measuring wrong.

What is your opinion?

Thanks, Nicolaj
