Alba Posted September 1, 2015 Share Posted September 1, 2015 Circa 6K miles I replaced my spark plugs with Autolite (AP3923)[bike is a 02 1150RT] I had a look at them tonight when doing the value gap and they had what I can only describe has a white heat look about them at the bent metal part (I know very technical). I have never seen this on any previous spark plug usual or something to investigate further? Many thanks ..... Link to comment
Stan Walker Posted September 1, 2015 Share Posted September 1, 2015 Well, the AL3922 is probably a better fit heat wise than the AL3923. One range colder. Harder to find. That being said, I run AL3923's in my '02 R1150RT all the time. They have always looked a bit whitish when I pull them out. Stan Link to comment

dirtrider Posted September 2, 2015 Share Posted September 2, 2015 Morning Alba That white combustion look is normal and is due to the fuel used & fuel/air ratio that the engine operates at. If your plugs are not heat degraded then going to a slightly cooler plug will not change that white combustion look. Reading spark plugs from a lean burn, o2 sensor controlled, no-lead fuel burning engine is a real science as you don't get that nice tan color of the old days of leaded fuel & rich operating conditions.
