ProTech Cylinder Question

[krusty_45]

Has anybody here run a 61x ProTech Cylinder in their 701? Notice any difference from a stock or ported 61x?
Im looking at buying one thats bored to 82mm already. Does it take a OEM sleeve if it would be needed to be rebuilt in the future?

Any help is appreciated,
Thanks

Those were built with race boats in mind.
Depending on what compression and gas you run, your bottom end may be weak.

I tried one and suggest you stay away. It might not be that bad for a Blaster but the bottom end is too weak for a Superjet.
