Nikasil plating..... who's doing it?

I hear you. I know it is off-topic, but cast do not expand at the same rate as Wiseco forged/machined. Every year out here I hear people *b-wordin' and moanin' about how they four-cornered their snogo motor using Wiseco. All they had to do was warm the machine first. Usually drunk, they start the sled and rip WOT.

Wiseco are lighter though, make your sled sound like an F1 machine.

If Wiseco started producing them for saws, I'd by their pistons in a heartbeat.

They make several pistons. Just have to know where to buy.

I feel weisco pistons have a target user. In a heavily modded engine they do well. Usually mod engines are set up loose from the get go, that type of setup is right up their alley. Now since race mod motors usually get tore down frequently you get the chance to inspect all the time. I also recommend them in very high compression engines where cast pistons will begin to collapse and a weisco thrives in these enviorment. Also ill run them on a jug between bores to save boring to the next size kinda a inbetween size if u will. Obviously this does not apply in a coated jug but in a cast jug it is a viable option.

I think cast pistons last much longer than the forged ones. Plus, as far as bikes are concerned, Wiseco often only offers a single ring piston where I prefer two rings. I shop for longevity over performance 99% of the time. Like if I can get a Mahle or an Elko for one of my vintage Huskys or KTMs, I will buy one of them in a heartbeat over Wiseco despite being more expensive most of the time. Pro-X has been making more and more, so I think they will be able to compete with Wiseco pretty soon for how many options they have available. And like Wiseco, I bet if you asked them about saw pistons, they would consider making them, for a price and quantity of course.

I had a run of Wisecos made for saws and to me they are top notch. When I first contacted
them about doing a run they flat out told me they don't do chainsaw pistons but we will do
them per my specs. Almost two months before the engineering was done. Had to make a
couple changes and then into production. I have sold a few and used quite a few in my own
saws with not one issue. Brake them in per there advise with a few heat cycles and good to go.
I use US Chrome for all my cylinder replateing and they do great work as well.

I've used 5 wiseco so far. I will be getting a few more soon. They're great in some applications.

I'm not saying Wiseco are BAD pistons, and for saws they might be great. But for the motors I build, they are generally my last choice; that's all
