but can say an infrered thermometer cannot be used on chrome exhausts. If you do, you'll just reflect and measure ambiant air temp.
Hmm, I'd argue that point, about not being able to use an IFR thermometer. I've tried mine and it seems to work, may not be 'xactly right though
. If you're thinking about the red laser dot, that's just to show you where you are looking. the Thermometer is reading the radiated infrared from the pipes.
I have a hard time getting a repeatable reading, but i think thats because of the shape of the pipes and I have to make sure I read at about the same spot on each pipe, the hottest is at the sharp downward bend. I tried the IFR Thermometer just after starting the bike, and letting it warm up, the first time 1,2,&3 were reading around 260-280or so, and 4 was at 180.
after rebuild all are reading about 220 to 240. It seems low, but I was more interested in the difference between the pipes rather than the exat temp.
