Piss revver
The vid is up there somewhere. It's got fresh rings in it, so I expect it to pick up a bit more power.Post a video of saw cutting.
I was going to go the Wiseco route, but they've been out of stock for awhile on CCC, so I just went this route. I suspect that even the Wisecos on CCC's site aren't going to be a direct swap, not enough room on the intake side w/o grinding IMO.You ever use Wisco pistons ?
They do, Wiseco will build a piston for anyone that has the money. Theoretically, the Wiseco pistons are better than the stock pistons, they're forged and have lighter weight w/more strength. The stock cast pistons can start to crack with high hours.Dose Wiseco machine pistons fir saws? I know they do fir dirt bikes. Im not a Wiseco piston fan. They're MX pistons are really light to shave weight fir MX racing. They don't last as long as other after market pistons like Vetex or as long as OEM from what I understand. However, I may be wrong about that.
Wisecos gets a bad rap on a couple different things. First of all, they expand faster than stock cast pistons, so quite a few guys don't warm their bikes up well enough and cold seize. The other is that they often are just offered in one size for each application. As you probably know, bikes often come with A,B,C, and sometimes D bore diameters. Sometimes you end up with a bike that has a wide D bore, but the Wiseco is one sized with a tighter bore in mine. So you end up with piston slap.
In addition to my Betas, I've got my old big bore yz250. It has a 293cc cylinder(same dimensions as a Ktm 300.) Wiseco was the only option when I was running that bike...luckily, the cylinder was honed for that specific piston, so it had a nice tight fit. A lot of guys just buy a new cylinder when the nikasil wears out, but you save money and get a better product if you send the piston you want to use in with your cylinder to a plating company like Powerseal or Millenium. They'll hone the cylinder to perfectly fit that piston.
EDIT: I'll add that I run OEM or Vertex in my bikes nowadays. Nothing against the Wisecos, it's just that I get to pick what piston diameter I want and I replace the piston before cracking ever becomes a thing.
