Powercoating stock head pipe?

[ckassen]

I have a friend that will powerdercoat my exhaust for free as long as I sandblast it and get it ready. My question is, how hot does the headpipe on a 00RM250 get? That is the only problem, because if it ends up getting too hot I would have to ceramic coat it and that would cost me a little....

you can't powder coat exhaust.
Ceramic coating is your best option. :ride:

you can't powder coat exhaust.

Yes you can...


Oh, you said exhaust.:laugh: That can't be coated, but you can powdercoat the head pipe as long as you never operate the bike with it installed (the powder won't survive the heat).

Are you sure, I have been informed that powerdercoating can withstand temps of 500+

What temperature do you believe comes out of an exhaust?

 

[ckassen]

That is what I dont know...I know that when fully warm and at idle my streetbike exhaust gives temps (at highest temp) approx. 375 (while stopped) at the hottest point on the header. 1.5in down from the mounting bracket.....But that is a 4 stroke, 3 cylinder, 955cc injected bike.... And that is at idle, I do not know if it would increase or decrease with the RPM's raised. So I was basically wondering if anyone knew what the hottest temp (at any time) is on a 2-stroke 250.....

EGT's will run about 300 degrees F at idle to 1400+ degrees F under an extreme load

I read this somewhere, I think that it is car related which implies roughly 8000 RPM max.

Beyond that, try doing a little window shopping for Exhaust Temperature Gauges. When you do, take a look at their ranges. If you find one that doesn't reach 1200 I will be surprised. I am certain that your 2-stroke will exceed 1000 if you actually ride it.

Also one ding and the powder coating cracks and pops off because it is very brittle

 

[ckassen]

That answers my question.....thanks...

1250 -1450 is a typical range for a gasoline engine running at full power...

The cooler temp would be a little rich and the higher number a little lean. To lean and it'll run cool because it won't run good enough to make power.

even IF i could powdercoat my exhaust... i wouldn't 'cause one shot of roost from a 450 in the open class and BAM it's all gone :P
