I had thought the original post about not much gains and just noise was about a bark box. If you pipe it the wee saw wakes right up.

It can wake up all kinds of people

Can’t beat a couple of pipes in the morning [emoji23]

More pipes [emoji16]

The bigger ones for a 372 big bore with a 272 piston I’ve built. Will see how it runs.

This will be going under the knife very soon.

A couple of saws I’ve just finished. Found a recipe I’m liking for the 550xp mark II. That MS440 is a clean saw, not done much work. Nice to work on them as they’re getting rarer.

What did you do to the 440. If you don’t mind me asking 😉

 

I got a 10mm  I’d like to enhance a bit more 👍

It’s had the squish band cut, base cut, port timing altered (exhaust intake and upper transfers), ports widened / reshaped, ignition timing advance and a muffler mod.

Here’s some pics of the squish band before and after and the muffler mod.

Ping me a message if you want and we can have a chat about doing yours.

I had put this in dons thread but thought I’d put it here too. Finished it last week. The 592 is an awesome saw. Even better ported 😁
