I just was wondering why no one ever polishes the crown of pistons? Or at least those that do don't talk about it. I polish my head and exhaust port to keep carbon from sticking. why not the piston crown?
piston polishing?

I never really thought about that. Thanks for bringing that up. If you get a chance, you should do a DIY for polishing the internal engine parts. I assume that it would probably make your engine last longer than usual.
I'm single right now so polishing is my favorite hobby. when i'm not in the garage doin it i'm in my room doin it. lol
ok back to the original "piston" post, well im on the trike forums and from what i have picked up its not really worth it, same for the ports, it will work for little bit but it wont be long before the carbon sticks and build up
so theres you answer, lol coming from old guys who have been riding for 30+ years ahah

I can polish the top of a piston in like 20 minutes. not much work. and polishing the exhaust port is proven by ken to keep the carbon build up next to none
do it if you got the time and desire, i wasnt telling you not to do, just said its not worth it, but i sure just making the port poished all shiny and smooth WONT LAST very long at all, getter put together, and ride it for a month, take the pipe off an snap some pics, im almost willing to be it will be carbon coated
I'll take that bet blaster01. Awk and I pulled the wifes Blaster apart after two years of running and found zero carbon in the polished exhaust port. The 208cc I ran all year has zero carbon in the polished exhaust port. Ian and I pulled the top end off of my 240 and found zero carbon after five tanks of gas. My experience tells me a polished exhaust port will help to prevent carbon build up. As far as polishing the top of the piston, I can't see it hurting anything. Just make sure you don't touch the sides of the piston. Josh Lyons owns J-Bone Motorworks and he's a good friend of mine. He polishes the top of the pistons in all of his KTM motocross engines.
would it be reasonable to assume carbon buildup can be directly related to the kind of oil you use?? i use super m and dont really have a carbon problem, i used benol last year and holy balls!!!!!
well i am gona run the same kina oil as ken does so i guess my exhaust port will be shinny after a year too. and B01 ken has shown an exhaust port that has been ran, i think it was his wifes when awk blew it up.
Well the exhaust port doesn't have combustion actually taking place there so thats why less carbon builds up.
You could do harm if carbon builds up on the polished piston and then flakes off during ridding.
I'm sure good oil plays a part but gas is just a dirty fuel.
Case in point, when you run alcohol.
No matter what oil you use carbon will never build up.
Here's one of my pistons after 35 gallons.

I ran Maxima Super M mixed @ 32:1 with Sunoco 93 in everything. Running junk oil to see if I get deposits is one experiment I'm not willing to do. Plenty of members have polished their own exhaust ports and I'm sure some of them are running other oils. We'll have to get their feedback after some time.
Just a theory but maybe if you run the sh*t out of your motor and dont lug it around it wont build up useing any oil. I use Klotz and i had no carbon but i run the hell out of my motors.
