044 big bore kit

[hills bay performance]

My 044 is getting a little low on compression so im gonna do a new piston and rings . My question is does the big bore kit make enough of a difference power wise on these to make them worth the extra money ? I dont think the cylinder on it now is bad . I have a duel port muffler on it now and I do the majority of my cutting with this saw . Any suggestions will be appreciated

If I were you and you have a good cylinder just install new rings and crank seals. Worst thing maybe get a good meteor piston and you should be good to go.

Thats the route im leaning towards. But ive been curious on how much of a difference the big bore kit makes over stock size.

Have you run a 460? That's pretty much what it would become. It might have a little more power but for the money I would stay stock if none of your major parts are bad. If the jug and slug are ruined then I might go for big bore and see what happens.

Save your money and stick with OEM. If you do anything, go with an OEM 460 cylinder. If replacing the piston, might as well stick with OEM as well. You can probably get a new piston for $3x-$4x.

I'd keep your OEM cylinder for sure. The quality on some of those big bore cylinders are questionable. Save alittle more money and get it ported.

I got a 460 rescue model. Ive never really used . Im gonna pull it down and make my decision based on what I find .

raise the compression to 190 area.make a new base gasket from a soda can. that should give you.021- .023 clearance.clean up the ports a little.

Im probably gonna stay with OEM stuff is the 460 cylinder and piston a direct swap ?

I believe there is some trimming involved for clearance.

OEM piston kit is now cheaper than Meteor

It is not. Nothing difficult, but it's not just a bolt on deal. There are a couple threads out there on making the swap. I have an old one myself.

That might be something worth trying.
