(Top pic) Those rings look like they're practically heat welded to the piston.
(next pic) OK, rings are springy on at least part of the piston.
Cylinder doesn't look too badly scored, can it be honed or will you need to bore it out?"Mathematics are the result of mysterious powers which no one understands, and which the unconscious recognition of beauty must play an important part. Out of an infinity of designs a mathematician chooses one pattern for beauty's sake and pulls it down to earth."

Why would you need an oversized head? Not like it's that hard to do the machine work on the current one to make it work better with a larger bore.
You can get a .25 or .5mm over piston from Honda, I'm sure larger options are available from other sources.Originally posted by the_grinch@Thatch-you sound just like an old athlete that can't face the fact that his best years are behind him.

There are turbo charged two strokes, they have exhaust port valves to limit the blowby issue that junkie mentioned
However, those motors are fuking super expensive and needlessly complex for very little performance gain.
The only turbo two strokes that I have ever heard of being feasable are the giant two stroke diesel ship motors"We want to be free. We want to be free to do what we want to do.

however, 2 stroke diesels are completely different than 2 stroke gas engines - they roughly resemble gas engines in that they are overhead valve engines, so yes they actually have valves.Originally posted by the_grinch@Thatch-you sound just like an old athlete that can't face the fact that his best years are behind him.

Originally posted by Junkie View Postthere are more reasonably sized two stroke diesels as well - ever hear of a "4-71" or "6-71" blower? that refers to the blower for two stroke diesels with 4 or 6 cylinders of 71 cubic inches each. There were also plenty of other sizes made, those are just examples...

The blowers on 2 stroke diesels are to blow the fresh air in, similar to how crankcase pressure does on a gas 2 stroke.
I'm not sure I'd say "most" either - and it's a very different type of valve than 4 strokes have, while a 2 stroke diesel head looks similar to a 4 stroke head.Originally posted by the_grinch@Thatch-you sound just like an old athlete that can't face the fact that his best years are behind him.

Originally posted by twostroke View Postmost twostroke's have Exhaust valves.
The exhaust valves I was refering to were tried on gasoline turbo two strokes and used to completely shut the exhaust port in order to prevent blow by"We want to be free.
