Anyone on the board convert their 750 to a 900? What would be entailed? Anyone know the cost of a used 900 engine? I imagine you would also have to convert the clutch to dry also. Thanks!

Why not go big bore kit and hi-comp pistons. Must be many choices available.

It should be a direct drop in. Used 900s sell for around $1000.

What would a big bore kit and high compression pistons cost, including or lacking labor?

About a grand for the parts. Or you can have someone bore and replate your cylinders and buy the $300 big pistons, oh wait, about a grand.

Check this out if you're seriously interested:

no carbs, oil cooler, or clutch cover. But it's a definite start.

no replacement for displacement ;D

LiZrDthanks for the ebay link, i may look into this.

I think we're at the same place. If a used 900 motor and a big bore kit/hi comp pistons are the same money, I'm thinking the kitted motor is likely to be much stronger. Not to mention that you're guessing the history of the used 900 motor.

Stock 904 engine with "proper" 900 heads and a jet kit in the carbs makes around 72 hp. You'll spend a good bit of money on the 750 to get there.

ebay auction is over at $733 but reserve wasn't met. Might contact seller if you're interested to find out what price he's wanting.

Put a 900 motor in but do the 944 kit to it. Mine puts out a decent amount of power. Id guess (butt dyno) with the 944 kit and FCRs Im at about 85-90hp. just a guess.
