I thought I was having electrical problems so I changed mine. My speedo kept reseting, replaced it twice thinking it was defective. I got a NGK BPR6HIX iridium from Discount Auto for 7.99. But be careful because of a clearance problem on some motors because the iridium plug is a little longer. the 49cc are more prone to this but still can happen to a 66cc i think. This is just what I have read on here about the plug. I also took the advice from a fellow mb'er to solder my plug in connectors. Then went to a place locally and bought a better piece of insulated wire and a new water proof cap, which they use on dirtbikes. My motor seems to rev better but I'm still breaking in my motor. It also eliminated my speedo problem. I hope this helps you a little, I'm still learning alot myself with this new hobby. Good luck
