I bought a new bike with kit installed. New engine, brought it home drove it about a mile then it backfired and cut off. Stopped getting spark. Bought a new magento and cdi decided to upgrade plug as well, The book that came with the kit suggested a NGK BP-L gapped to .6 or .7 if needed. Installed all new parts with plug gapped at .6. Btw I redid all the wiring to make sure they weren't crossing.blue to blue and black to black, killswith red to blue, and black to black Bike started 1st try drove it about a mile and it did the same thing backfired and died. No spark again tested magento reads normal 332 ohms can't get a reading on cdi though. Could anyone tell me why I lost spark. Also tried new new plug in old cdi and magneto set up no spark till I replaced the cdi the 1st time. Can someone help me please?
