Bought a 265 paul turner hyperdyne cylinder on ebay last week.
I know its a nikasil coated aluminium sleeve and the guy told me its a top end port job. Haven't been able to find much info on the
hyperdyne anywhere. Wondering if some of you R guru's could tell me more about what I bought. thanks

No picture the cylinders not here yet. I know about nikasil-my
snowmobile cylinders have it, I know its expensive to have done
and is supposed to last a lot longer without needing boring. I was curious if anyone had run a hyperdyne cylinder and what they thought of it, what its characteristics are, what it was built to run like etc.--it had to be made by duncan racing so I'm guessing there's some of them out there.
