Operating Temperature

[Nightbiker07]

I was wondering. what would be an Ideal operating temperature for my 84 R?

where would be the start of overheating? i want it to be jetted correctly, and i dont want it too lean and burn it up.

i have a really good thermometer to check the temp, so that isnt an issue.

does anyone know the ideal operating temperature and the temperature considered overheating?

But your plug check will let you know a very close estimate. If the plug is whitish or a very light tan its running lean=hot. This is air cooled. You cant just let these things idle at a stop like a four stroke. Keep the mud cleaned out of the fins.

When jetting do some plug chops. Your plug should look tan to brown.

im guessing 290 is getting a little hot, what are you mic'n? I mic the plug since it should be the hottest part - I will check mine next time I ride it and let you know what it reads.. it is fat so should be cool.
