Before the coated pistons there were a lot of issues with damaged pistons at the exhaust port, they looked like they had to less lubrication in conbination with a tight pinch and so the surface of the piston showed as it was rubbed.
The coating was a some kind of DLC which creates a very low friction surface. But after running in the part where it touched the sleeve most had no coating anymore. Probably they have done it to give it a smoother run-in for not damaging the piston.
In the real automotive industry (as I was tod for sure with Mercedes) this is also done a lot on the crankpins.

Also, out of the 9886, 2052, 2015, and 2006 pipes which has the most top end?

If you have an unlimited budged go for the latest top model. If you are just a good or less driver (and to be honest, most serious drivers know what to choose) I would go for the rocksolid 35-plus-21 with a steel bearing. It is affordable, has goed performance and the steel bearing last longer.

Yesterday i tried using odonnel 77 and after inspecting the plug it did look like the underneath whole is much bigger than the nova one so compression is reduced and it was also felt on the track especially the acceleration.
Am i right or is the clutch slipping a bit
Engine is a 12PT

Step 3, is that continuous 750cc of fuel or heat cycle every tank until 750cc has been run?
Step 4, same question as step three, heat cycle every tank or continuous for 750cc?
Thanks for all your help. You're deffinately an asset to this hobby.

Step 2, when you say establish a rich idle, do you mean start it at factory settings or lean it on the top or bottom a little?
Step 3, is that continuous 750cc of fuel or heat cycle every tank until 750cc has been run?
Step 4, same question as step three, heat cycle every tank or continuous for 750cc?

No need to heat cycle each tank. In between each 750cc is fine.

How's this look? Nothing special, just starting the break in process. Idled through 150cc tank today. Next step tomorrow. So for the next step, should i just leave the needle settings as they are from factory and run it for another 750cc or should i lean it a little? Thanks for the help.

Question, step 4, should I go ahead and reduce Idle gap to .5mm and tune the low end slight rich so I don't get that pinging sound at the end of a run when I let off? If I don't it will race after a pull through the rpm range because of the big idle gap and rich bottom. I already richened the hsn to get plenty of smoke and lubrication. Thanks.
