Cub cyl


Recommended Posts

the "cub" cylinders are 68mm in bore size.. the difference in size of motors are....

 

stock stroke 68mm - 392

 

4mil stroke 68mm - 421

 

7 mil stroke 68mm - 443

 

10mil stroke 68mm - 465

 

pretty much a ton of combinations, depends on the power your wanting, what your wanting to spend

wrong.. "most" cubs are 68. however you can get them in any size from 64 to 68.... For example I just sold a 66 bore cyld.

I'm thinking about getting some cub cyl and I found a set of cub cyl that are 398 or something like that. I thought that cubs started at 421. Can someone explane to me the differences in there cyl to me thanks.

 

398 is a 66 bore 58 stroke.

 

 

the cub he mentioned in his first post was referring to 68

 

must be seeing something Im not

So a stock strok 68mm 392. Is that a ok setup to be running. I have never heard of this most of them I hear of are 421.so if I wanted to in a year I could go with 4mil with this same cyl ....

yes, but you have have to get the cylinders ported for the difference in 4 mil port timing

no, the port heights on a stock stroke cub to a 4mm will be raised too high.... now if you spent a bunch of $ to get the cylinder welded up, reported and plated, along with some custom domes, different pistons and base gaskets you could run it but that would be the ass backwards way of going at it.
