Thoughts on powder coating cases

Recommended Posts

Looking for thoughts on powder coating my cases and jug and head on my bike . My last bike I built I had it painted and did not even last one season . Washed on very low pressure even. Looking for some opinions . Thanks

anodize is the proper way to go as far as scratch resistance, durability and heat transfer.

 

also powder coating covers the microscopic porous of the aluminum and acts as a heat insulator, though you could powder coat the side cases only if you wish but avoid head, cylinder and cases.

 

best is just media blast the bare aluminum 🙂

Ive never heard of people having overheating or performance issues from powder coating. With that being said I'm no expert and I've never taken a poll on the subject. Is this something you've experienced performance issues with?

I strongly agree with you

never had personal experience with this but is simple thermodynamics, coating the whole engine will make dissipating heat more difficult because of the powder forming a layer and because of the paint properties it will act as an "insulator".

 

you may not notice engine performance drop or overheating but the operating temps will rise by a few degrees so possibly at higher ambient temp you may notice overheating more easily. on the other hand is safe/good when running the engine at low ambient temps, will help to bring up the engine temp easier.

 

purely performance wise - bare aluminum or anodize is best choice imo.

lots of guys do this.. I've seen 4 stroke guys do their heads, cylinders and cases and never have reported any issue with heat. I'm sure that is true, but i doon't see the amount of heat it's preventing dissipating will not be detrimental to the engines life expectancy

 

How many engines came painted back in the 80's? I haven't done my cases, head or cylinder yet, but I've shot everything else on my 250 lol

Thanks for the input guys my cases are soda blasted raw right now . Want to go back black like it was from the factory . It's an 89 250 . If the cases did not look a bit beat up I would leave them raw . I've seen some bikes engines fully coated . I thought it might raise the temps . But never heard anyone really say don't do it it won't work . .

powdercoat them its fine, will look great. these are liquid cooled engines for petes sake. And even if they werent, How many monster hp air cooled v twins have i seen with powercoating etc
