Re: Still having heat problems :(
A nicely tuned HT will run at ~180C when WOT up a hill.
The pipe 1" from the head is about 10C hotter.
When lean expect 10C more & 10C less when rich.
When lean the pipe gets 25C or more hotter, the opposite when rich.
Idle temps are 30 to 50C less.
I use a non-contact thermometer for initial tuning as it saves pulling the plug over and over, saving the threads.
The head & pipe needs to be painted black where measuring and the readings are taken next to the plug. My numbers are at sea level and 20 to 25C ambient.
