Nothing against SBT especially when you're just the average coucher looking for a STOCK motor that will give you the piece of mind of having a great warranty, but personally I wouldn't buy one for a superjet that I wanted to mod. You could probably rebuild your motor yourself for less. I've never rebuilt a motor myself, but I'm pretty confident I might be able to especially with the help/guidance you can get on this site.

62T cylinder is a 760cc
61x is 701cc

62T cylinder -760
61x cylinder -701

Single carb 701 - X cases, X cylinders
Dual carb 701 - T cases, X cylinders

Dual carb 760 - T cases, T cylinders, yamaha calls it a 64X

6m6 cases/6m6 cylinder = 650 sj
61x cases/61x cylinder = 701 single carb sj
62t cases/61x cylinder = 701 dual carb sj
62t cases/62t cylinder = 701 dual carb raider
62t cases/64x cylinder = 760 dual carb raider/blaster 2

I think that's the way it goes,
 
62T cylinder -760
61x cylinder -701

Single carb 701 - X cases, X cylinders
Dual carb 701 - T cases, X cylinders

Dual carb 760 - T cases, T cylinders, yamaha calls it a 64X

Yes I know all of that, but I remember someone telling me that there is also a 62T cylinder that is a 701. I was told it's basically an 81mm cylinder with the 62t port height and that's what came in the 701 Raider.

Not sure if they were right or not though.:dunno:
