temp gauge tuning

[bobbygerard]

Hi

Just got a cheap temp gauge 10mm too small to fit on the spark plug. Would placing it under one of the head bolts still give a accurate running temp? What temp range should be looking at achieving.

Greetings:

I ran mine under a headbolt for a couple of years. Temps seemed the same, plus or minus 20 degrees. Added advantage of not having to screw with the wire every time you pull the spark plug.

Cheers for the advice guys think im running a little rich top temp 270 when wot and 292 when turned the engine off.

Mine is runing 280 just cruising and at top speed runs only hitting 335 or so and drops fast To rich ? I have malossi cast bbk 24 mm oko it has 115 main in it now

I have the same but I'm only on a 86 main. Is yours ported. Every seems to be using much larger jets than I. If I put a 92 or higher it spits and is slow of the start with the odd back fire.

[Dustyn2007]

Yes I ported mine Mine isnt back firing or anything just kinda doggie at full throttle yours sounds like way to small I used 102 on stock carb

i was just about to ask how hot a motor should run. Just put a bigger carb on my bbk af05. The highest temp i have seen so far is 325

380f is about as high as you should go.Ive seen spikes of 410f and no damage but i dont recomend it .Keep it between 330f and 380f .
