I put together my kit. Ran fine for about a mile then it backfired and cut off. Couldn't get a spark after that. So I bought a new magento and cdi decided to upgrade my plug too. The book that came with the kit said to get a NGK BP-L, and to gap to .6 or .7 if needed. Installed everything and gapped plug. Started right up the did the exact same thing about a mile down the road, it back fired and cut off again. No spark tested magento it's in normal range. Cdi reads 0 though. I've made sure wires can't cross. Blue to blue black to black/ kill switch yellow to blue and green to black. Could anyone help?
