One cold exhaust header, is that bad?
Help Support VMAX Forum:
I assume this is taken at idle?
Would have thought that all temperature should be similar therefore there is an issue.
If it is significant or not that is another question.
An over-rick idle mixture will reduce the combustion temperature but I have no idea by how much.
Another alternative is a misfire.
You could try swapping plug, cap and HT lead from one side to the other and see it the lower exhaust temperature moves with it As it is one of the front cylinders that is easier said than done.
If the bike is performing OK without any noticeable drop off in performance then the obvious thing to do is to throw the thermometer away and just enjoy riding the machine!

Thats just above body temp, you probably have a fouled plug. which could be from many reasons Maxmidnight explained, or just simply a plug gone bad.........
