Husqvarna 359 porting

[rolloman]

does anyone have any info or experience porting this saw?

About the easiest saw to port with very strong gains to be had. Get a non EPA 357 muffler to start with and add a couple 5/8 outlets. Lots of piston skirt width to take the exhaust and intake out nice and wide, but keep them low. Then give the lower transfers a good work over, they are ugly in stock form.

What do you mean by this Brian ?
This is one saw I'd love to get , I'm sure they can make a fantastic "worker" after the above mentioned "tweeking" :kilt:

Don't try to run 180 degrees of exhaust durration and 170 on intake. In other words don't try to mess much with the factory timing. The 359 can be made to cut nearly twice as fast as bone stock without straying more than a few degress from factory port timing.

Got started today and managed to get the exhaust port widened, corners squared up and ports aluminum surfaces smoothed out. Starting to look at the transfer ports now to decide how to attack these. I am not raising or lowering anything just widening and trying to imagine any transitions that would affect the flow and smoothing them out without removing anymore material than necessary.

359's are great because they have transfer windows that can be removed. You don't need any special tools to do the transfers.

Here's a couple ported 359's from T-Wolf's GTG......

I noticed that too.... I think one vid is the 0-60cc class, the other is the 0-80cc class. We ran the 359's in both classes- and did pretty good against those 372's and 460's!

Thats right. Might be good to do a gtg again come spring.

I'd be up for another GTG. Marlbank happens in the spring too, May I think. You should go this year.

Hey, good to see you here! I didn't know your username here until now. You're right.... I think T-Wolf's "stock" saws woulod fit right in with the rest of the "stock" saws.
