Better yet get you some 900 sleaves & put them into your upper F3 cases with 900 pistons. There will definately be some machining work but has been done. With the difference in stroke & the increased combustion chamber it comes out to a 698 I believe. Ive seen 2 in my 10yrs in the industry & they were screamers.

There are no "upper" cases on the F3. The crank and engine are one and the same. You have to split the cases. in half... That kind of a stroke up will kill the bottom end of the engine in no time. The 900cc engine swap makes more sense.

Is that better?

The words I chose to use doesn't matter...
The crankshaft & the engine cases are NOT one in the same. The crankshaft does go inside of the engine cases, as does a few other parts & pieces. There are 2 halves to the cases. Upper & lower case halves. They aren't even made of the same material & they should never come in contact with one another in a well running engine.
The 900 crankshaft will not even go into a set of 600 cases. The 900 sleaves can be installed into the UPPER case halves of a 600 with some machine work once the 600 sleaves have been removed.
