365 to 372 rebuild

[BugaBoots]

I am currently thinking of replacing the jug and piston on my 48mm 365 for something different. The problem is that I don't know what cylinder is going to work best. I have read that the bb kits don't really gain on the stock 50mm. Just wondering what you would pick for a replacement jug to turn it into a 372?

If there's nothing wrong with it I'd keep it as is unless you want to run 28-32" bars. Then I'd find the Xpw cylinder if it's going to be stock.

Well with it at 65 it doesn't really have a lot on my 6100. I figured if I bumped it to 71-75cc it would fit nicely between my 2186 and 6100

If the 48mm is a closed port and in good shape, just have it ported. It'll smoke a stock 50mm & 52mm top-end. But if it needs replacing, get a oem 50mm 372 top-end...

It is an open port top end.

It is an open port top end.

I have seen some strong open port 365s, but in that case I'd likely go with a oem 50mm top-end.

I have ported a OP 365 that is strong.

Go used OEM/ meteor piston.
