Hyway cylinder

[SamVT]

Anyone else see the info from hyway , looks like they have a 57mm kit for the 390? Am I reading that right? I do have a donor saw I would try it on . What do you guys think ?

I've had good luck with hyway cylinder in the past doing cheap builds for people that couldn't or wouldn't spend the money for oe, and the off chance that oe wasn't available. The had a sweet hybrid 357xp/359 cylinder that kept the 59cc displacement but had closed transfers. Ported it's ran very well, I keep it as a back up saw. I just did a ms390 for a co-worker using a "dukes" cylinder and I'm 90% sure it was a hyway cylinder repackaged. It was decent and I didn't have to clean much up. Co-worker was happy with how it ran and the cost was 1/4 of oem.
