Spuds Porting and Tuning Thread

[Darkslider]

I'll jump on the bandwagon too and ask for some prices, though I don't suppose you'll have done a saw like mine yet (Solo 646). Do you need to split the head and crankcase to do the porting properly if there's no internal work required? I know you would if you were dropping the pot to raise compression but do you do this on every saw?

 

The saw isn't that old and has probably done less than 50 hours. Reason I ask is finding gaskets and spares is a nightmare for it so if it's just a case of removing the carb and exhaust it'd probably be doable, but any further stripping down and you might struggle.

You look like you are going to be busy Spud .

No pm yet , my 372 is an 03 non xtorq, she is old but has done very little.

As was mine . Ported by Steve a few years ago and still going strong . He has a vid of it on here somewhere.

Nope, not ported any Solos to date. Your saw is of a strange construction, a sort of clam type crankcase but split higher than usual leaving a cylinder more like a vertical split crankcase which is good.

 

The cylinder would need to be removed to do the porting unless it was just a muffler mod being done. On some saws you can drop the base gasket but depends on the squish clearance set on the standard set up. You can machine pistons, cylinder bases and squish bands but don't go this far on woods ported kit although we have done a few in our time.

 

Gaskets - I hold a wide selection of gasket material so make my own up where necessary.....you can't keep a good man down:sneaky2:

In other words , he can fix it !

[wisewood]

Is there much gain in performance from a muffler mod on bigger saws? Is it just a simple swap for a dual port or would I need to drill out/remove baffle?

[Countryboy]

Price list for me to please Steve

[Rich Rule]

I can confirm Steve's work.

 

My rebuilt and ported 660 with dual port muffler goes like the clappers.

 

It is a tad loud though
