It's the pick up coil. 12.00 dollar free shipping part on ebay. Trust me its the pick up coil.Did any one work out what the problem is yet.
I have KLF300A and B.
both have the same problem. The A model started having the problem first while the B was fine. I swapped the CDI between these two bikes. Had the A going for a couple of hours, now back to the same problem. I have changed every part of the ignition, cleaned the carby a hundred times, even tried a new carby, reconditioned the engine.
Timing chain to specs.
I also have a C model and fitted their CDI, but didn't fix the problem.
Idles fine but back fires when I rev it above idle.
If anyone had ever fixed that problem please let me know how.
