Did not know that about Victory. Interesting.
A thing to think about using these things on airplanes is most of the time airplanes operate in cool to cold temperates. Big aircooled motorcycles engines have terrible heat issues. And there is very little RPM changes compared with Harleys or any kind of on the road vehicle.
Not really comparable but sounds good at first.

I spoke with both Revperf and Wiseco's head of R&D on this issue. The old kits were sold with CP pistons and different rings. RevPerf now sell the kits with Wiseco pistons and rings. RevPerf changed to Wiseco pistons about a year ago. They have spent thousands of hours of testing to prove out this set-up.
I believe that a few had problems with the earlier kits. Other jumped on the bandwagon from too much internet surfing and made the issue bigger than it really was. You know how it goes; I know a guy who knows a guy who is the friend of a friend who's bother-in-law had problems.
I would have no problem using the Nikasil cylinders.

Nikasil has been proved to have failed in various motorcycle cylinders, airplane engines, and snowmobile engines. Just do a search on Nikasil Cylinder Failures, and Millenium Cylinder Failures and you wil quickly see. Both brands above are from RevPerf and I was also burned with their 107 cylinders. Never again!
I've had nikasil cylinders for 2 years now and no issues. I suspect there are far more that have had no issues than those that have....you just always hear about the ones that fail.

Well an airplane cylinder runs in mostly a nice cool temperature and mostly a pretty steady RPM. No dust much.
Probably that kind of stuff with motorcycles is hard wearing.
My brother's first car was a Chevrolet Vega. Had those cylinders. Wasn't a coating the whole engine was made of that. Didn't last long.
As someone said, tried and true.

do you still have those nikasil cylinders ???
I purchased 3 sets. All 3 burned oil and knocked. One set even delammed. Rev perf told me to stick it up my *** pretty much. Now, i see they changed piston design and new ring packs. Great for them, i hope they figured it out. But i must have assembled all 3 of my motors "with honing remnats in the cyl walls". "Sure we will warranty your cyls, but those 300 dollar pistons that are now shot are not under warranty." So, anyone want to buy 3 sets of pistons and cyls with low mileage???? They run super cool...all the burnging oil took the temps way down.....
sorry struck a nerve.....
