Ok so I've researched engines and/or options for more power but I can't find out if I can put 600 cylinders and pistons on my 400 to make a 443. This set up would be similar to yzf cylinders/pistons on the 600 bottom end for the 660.
Can anyone shed some light on this?

1990 FZR400 with a Kerker exhaust for now. In the process of fork swap, shock swap, and 17" rear wheel
Re: Cylinder choice
The 600 piston wrist pins are larger than the 400... so the 600 pistons will not work with the 400 connecting rods...
Re: Cylinder choice
If you are just looking for more power, the easiest option is to swap a FZR600 or YZF600 engine into your bike.
Re: Cylinder choice
A YZF600 top-end is possible with machine work. I don't think that you can machine the FZR600 cylinders to the proper deck height. "Easier" is also more cost effective in this case. 
FZR400 (1WG): Purchased a perfectly good FZR400 with Yoshimura slip-on/EXUP, Yosh jet kit, Factory ignition advance, Racetech springs and emulators. It even had great bodywork. Like some diseased maniac I had to mess with everything good about that bike. Well, at least I have better brakes now.
