27cc BBK & 1mm stroker & stuffer

[pedhead7]

Whats up wit the new 27cc bbk? Is it superior? Is it a "sikk toys"??? Same with the Stroker. Also why do you need to run a extra thick gasket with a supeior cylinder and the new stroker?
I thought they where idintical to the Zenoah.................

The new 27cc big bore is NOT a Superior or an ADA Racing product. It is made by the same manufacturer that makes the one for Sikk.

Both the Superior 34mm big bore and the new SK27 big bore need an additional base gasket for use with a +1mm stroker. This is due to the piston to head clearance being closer than the Zenoah, which is better for performance. The Zenoah cylinder has approximately .020"(.5mm) too much clearance on the stock stroke. Must just be an oversight by the engineers at Zenoah
