and might it impede heat transfer?

It may impede heat transfer it may not, will find out, if it does a bigger rad goes on, can't say it did my valve any problems, nor plenty of other liquid cooled 2t that I know of.

It'll stay on the engine no problem, think it's ok up to 400c, think they now what they're doing with it a Triple S, can't see them doing it if they're going to get a load of come backs.

I just want a nice easy to keep clean engine. This seemed the favourite for this bike, not saying it's for everyone.

wasnt saying that SSS didnt know what they doing just a never seen enignes powder coated like that

The engine looks great Mark.
The laws of physics say that black aids heat transfer, so if anything it should help.

you put an extra layer between engine and surrounding air and that should be helpful?

It might make a difference with an air cooled motor, but I am not so sure with liquid cooled jobbies, surely most of the heat transfer is going on inside the water jacket? I could be wrong though!

I agree, but some direct heat transfer to the surrounding air will still take place and I'd be interested to know if the new layer would result in a (very) slight engine temperature increase. The increase (when there is one) probably can only be observed with a digital temperature gauge I guess.

I have the dubious pleasure of living in Yorkshire, where it's always friggin cold and wet, I seriously doubt that a coating on the engine will make that much difference when most of the time the temp gauge barely rises off the rest

And if it does, bigger rad goes on, which is likely to happen anyway, again that will mainly be for aesthetics as is the powder coating. When I sieze it through it being too hot I'll let you all know and you can all go 'I told you so'

in 10 years yorkshire will be tropical, so you better prepare yourself

Costa del Grimethorpe and Playa del Heckmondwike have a certain ring to them, I think.

Look lets put this black painted engine puppy to bed
Energy radiated per second:
H = esAT4

e = emissivity (0-1)
s = Stefan-Boltzmann constant
= 5.67 x 10-8 J/(s-m2-K4)
A = surface area of object
T = Kelvin temperature

Obvious isn't it

Does that mean I've f**ked up?

I dunno but that f**ked my head up
