Spark palm reading

#1

Post by ericheath »

Looking for ideas on what this might indicate. It's on two plugs. Ash? I have about 1000 miles on my new head gaskets. No issues. Looks like a little lean. DPR8EA gapped at 0.025"

That plug looks pretty normal I would heed gltriker and put the plug back. :-D I think that the new gas formulations have lots of cleaners and additives in the mix these days for the latest generation of automobiles. The higher the grade the more additives they seem to add up here in the gas.
Current Bikes:

1966 CL77 - Honda 305cc - Dual purpose - "Gentleman's Scrambler" was a period moniker.
1967 CL175K0 - Low production number with #802 engine serial- winter 2019/2020 full restoration.
1972 CB350F - Baby Four with low mileage - Cosmetic refresh to the next level 2021/2022.
1978 CB550K - Very original bike with only 7499 Km. from new - light cleanup and refresh done.
1983 CB1100F - Canadian model - DOHC Supersport in pristine low kilometre condition from new.
1984 GL1200 - Standard model in showroom condition - two owner bike from new.
1984 CX650E - Restored summer 2017 - a rare Eurosport model - excellent one owner bike.

Good, I wasn't worried but a lot of my lack of worry is naivety.

Is it possible that it is not build up but more like the dark color flaked off exposing the light color under it from a previous run down the highway?? Either way I am with put them back in and enjoy the ride
