Well I have fattened it up a bunch and now have the biggest jets I own in my carbs and the motor is still running 185 degrees still seams to be a little to hot with alcohol to me. Motor was wantn to run over 200 be for. I have jumped the jets up a lot. But I think my EGT gauge isn't worth a crap it still reads the same and I've picked up over 1/2 second. I would think the actual EGT would have changed.
