I have a 1200 Fxe with .60 over wiseco high compression pistons. Would this be considered a 1340 now?

 

Well you got the bore part of it , all you have to do is find a flywheel stretcher to get that extra 1/4" of stroke needed then you have the 80" .

 

You kill me, dude!
I have to assume you have the heads off if you know what type and size of pistons you have. Do one more step and measure the stroke. If the stroke is under 4", it's a overbored 74. If it is 4 1/4" its a 80. If it's more than 4 1/4, it needs to be presicely measured to see what it really is.

 

I had the top-end redone a couple seasons ago. It was punched out previously, so my buddy (mechanic) had to go .60 wiseco. Still have stock fly-wheel. What "cc" would this make?

 

The answer is 1249 cc or 76.23 ci

 

Actually there is no answer until, as others have mentioned, you find out what the stroke is.

 

if all is true orig stroke is 3.968 (74 CI ) then the cc's are as such

 

Knew the inch's but not the CC's , nice man . Been a long time since I cc'ed a combustion chamber on one .

 

Thanx for the feedback fellas. I know its a rather pointless question, but I always wondered.

 

Hey i got one more ? for you shovelhead gurus. How many teeth on a "stock" rear sprocket of 1977 FXE 1200 Super Glide? Just wondering Cuz I don't have that much lo-end off the start but I have plenty of gear on the highway. Still have the stock 4 speed. Was wondering if I have a taller gear ratio. If there even is such a thing..........
