The owners manual for my 1985 Yamaha YT125 calls for a Champion N10Y. NGK is hard to find around here so I had the local carquest cross reference it and they gave me an Autolite 64, after doing some research the Autolite 64 crosses to the N10Y Champion but NGk's part look up says it calls for a BP6ES. The Autolite 64 crosses to a BP5ES which is one step hotter, yet the N10Y crosses to both a BP5ES and BP6ES. Could somebody please shed some light on this? Thanks
