[jeffrey]

i am stroking my cheetah cub engine i have a couple questions first question can i use the sandard 795 wiseco pistons its not a bigbore

next question jetting on keihin 30 mm carbs i have 160 main now im sure ill need to go bigger any sugestions

[Bansh-eman]

yes anything smaller then a 66.5 bore will use 795's for a longrod crank.

 

Jetting there are many of fctors, whats the evel temps and other mods on your bike?

It will also help to know elevation, what pipes, what filters etc. I could be wrong too, but i think 30mm carbs are a bit small to get the most out of a set of cub cylinders.

i have dmc 916 pipes and k n filter and can i use the spacer plate like i did on the stock heads?

Ok, so i want to be clear exactly on what you are doing and asking. If I am reading this right, you have a 350 cub right? You want to stroke it to I assume 4mil? I have to ask why you want to stroke it? I assume you want more power. Now if you have the small carbs and dmc pipes, you are no where near gettting the potential out of that motor. I dont think adding a stroker crank and spacer plate is going to be the way to go here. I think you need to invest in some cpi's or shearer pipes and some at least 35 mm carbs. From what i have been told the cubs have a lot of transfer port area and like large carbs. Plus the relatively high exhaust port duration of the cub cylinders is not favorable to pipes like the DMC's. If you still want more than that you may be better off selling your cub cylinder and buying one set up for the stroke. Just my .02 By all means, what you have will work, but i kind of think you may be money and time ahead to get some different components before you start going to work. Others will chime in.

yea im not following what youre trying to do man. if you want a 4mm cub, then buy the 4mm cast cub cylinders..

[jeffrey]

i already had the cub cyl and i already had the 4mm stroked engine now im going to combine them to make the stroker cub i was curios if anyone had any thoughts

[KaosBanshee44]

Before i chime in let me ask you this, are you still gonna run with those carbs and pipes etc. Your just sticking the cub on the 4mill stroked motor?

[Bansh-eman]

If you want a 4mil cub, sell the stock stroke cubs and buy a set that are cast for the 4mil already. Iam not sure if a 4mil casted cub comes in anything smaller then 68mm bore. maybe someone else will chime in
