Just curious if there's a range my blaster should be operating within. Right now I've seen it as high as 280 degrees.
Operating temp

Not exactly , just shows you the temp sitting still. The more accurate way is to get the head temp with a sensor under the spark plug . That will give you a better idea how the motor is doing under actual riding conditions. Trailtech,Digitron are 2 good units . The ideal method uses a digital exhaust temp sensor.
since I don't have one if those right now, is the thermal a good reference point for now? They should run cooler while operating right? Being air is moving over the fins. Mainly I just want to make sure I'm not getting to hot. I just did a rebuild and haven't got to plug chopping yet. I'm still breaking in the motor.
Lol, I feel the fins when riding, especially if riding slowly in high ambient temps through difficult terrain. Far from ideal, but gives me an idea.
The thermal gun is perfectly acceptable gor checking head temps, just dont wait too long after stopping to measure. Ideally check while riding.
The ideal solution would be digital head temp guage and an exhaust temp guage.
(Exhaust temp only, with liquid cooled motors)
I have built many turbocharged motors and use the EGT (exhaust temp) as my main referance! If you run lean, egt instantly goes up, timing issues too. I try and keep my temps below 750-800c on my turbo cars. ( have run it up to 1100c on one occasion, by mistake, and it looked amazing! Yellow turbo and downpipe, and fading to a dull red at the tailpiece. And way too close to the melting temp of the pipe)

So my temp must be within range. Because you guys don't seem to be concerned with the temp posted. I will def. look into one of those meters however. I like the idea of monitoring my engine.
I my experience roadracing air cooled engines (100cc to 250 cc) the cylinder head temp range was 250 degrees to 325 degrees . I have not recorded the head temp Blaster yet, but plan to.
I have a trailtech, and i think i hit 400 degrees last summer?
I had an air leak though. And this year so far, my temp gauge doesnt work. i will be looking into it

Regarding the OP, yes, I would guess that is an acceptable temp, would like it to be a tad bit lower, but thats just me, and I like my engies running cooler.
I however have packed in my meter everytime I go out, but never bother checking... I also want to know exactly where mine is running at, but its definitely under 140c in the fins.

We tested ours when they were jetted perfectly using a thermal gun. You are within range. Our temps on two different bikes were 260 and 270 degrees. This was after a long rip and a couple doughnuts. We immediately shot the head with the thermal gun. I would say you are good. HOWEVER I would trust the color of the plug more than the reading of a thermal gun.
External engine temp readings are no substitute for a plug chop, the aluminium melting fire that passes out the exhaust port cannot be measured but taking head temps.
Although a temperature test at the head will tell you that you may be running a lean mix, it cannot tell you how destructive the mix may be.
Please plug chop at the earliest opportunity.
I'm not trying to substitute. I merely haven't been able to break the motor in yet. But through that period I want a way to monitor if I'm running too hot. That's the only way I can at this point. The chop will be down as soon as the break in period is over. I'm trying to get to that point.
Well, this tool helps, a FLIR camera.
These pictures were taken in near freezing (0c) temps. Temps go WAY up in hot weather.
Temps go up over 300c in hot weather.

Yea that's sweet. I'm in Florida so I'm sure the temps will get higher.Well, this tool helps, a FLIR camera.

Good point ! Mine is still new too, 15 min actual run time.
Cool meter you have there... was looking at one when I got my laser gun, but the difference was just WAY too much to justify the occasional use of it.
