The difference in the chambers comes in the cb750f2 motors which are larger and have slightly bigger valves. But that chamber would only get you down into the 11's as far as compression. You would have to do some measuring but there are different thickness base gaskets, head gaskets, and you could do some work with the chamber to help lower compression. I think you could get the compression down with enough work and measuring.
I will have pictures of my shiny new 70mm pistons and cylinder once they get in
oh man i wonder what my 10041 number pistons are? I do not want to b uild a 12.5:1 engine, there is no gas that will run in it, and the starter wont turn it
I cant find any real definite information on these things, they are a cheaper cast piston and it seems noone kept any info on them. I am still looking for more info.
this is the 10041 Powroll piston. its brand new, but been setting on the shelf since. this cylinder has been bored, and decked for some reason, i may not use it. I am still looking for the darn rings they were here new in the box. otherwise i am gonna make a coffee table with them. these domes are pretty significant compared to stock
I wonder if those are 10 1/2 piston for a F2 head. They dont look like 12 1/2 but its hard to tell. They look a little smaller then Carman24 pistons. Do you have any stock 750 rings, the reason I ask is to determine what the width of the rings are. I know Total Seal can make a special set of rings if you give them the dimensions.
