    1200 motor in a 785 Pro

    Would it fit? why put a 1010 in when you could possibly put a 1200 in it? Can it be done? Has anyone ever done this?

    1200 is a domestic engine (red)

    785 is a Fuji engine (black/blue)

    A 1010 is a modified (longer stroke I believe) 785.

    Would be a big project to take on, when you can buy a PRO 1200.

    Sure you can do it, but why???

    How the heck do you make a longer stroke 785??? The rods barely clear the bottom case as it is! (And what parts are needed to do this?)

    I am still trying to figure out how to use a 785 crank with 780 jugs and pistons. I thought about 780 rods on the 785 crank, but that would still raise the deck height by 1.5mm and throw out the port timing a bit.

    Well if Pro Mick says its not much different than a "regular Pro". Although to me that looks extremly fast.....Wouldn't a fatter motor than a 1010 go even quicker and faster? I know you would have to change stuff around..mounts , exhaust and other stuff.. I think that would be sweet! btw .. Beerdart... the link doesn't work. opps!Or does the 1010 because of the stroking..make it better? Just throwing around ideas here. I was always taught... There's no subsitute for CUBIC inches!"


    xlint89... I want to see a pro do 70-85 mph! Seems like none of them can go over 69.8 (LUGS785 Pro) and it has ALL the GOODS on it. And he knows what he's doing. How About a Harley Davidson 100 cube motor? Those has tons of torque!. That would sound sweet wouldn't it? Use real harley pipes for it too! lol

    Wouldn't a 1200 in a pro 785 be way faster than a 1200 pro? the hull design and just the weight difference alone?

    No power valves on the 1200.

    My comment was originally directed towards gas valves verses motorized valves, not different bores and strokes of motors.

    Oh ok Mick.! That deal in CT sounds like maybe is a good deal.! So your saying that the 1010 has power valves on it and the 1200 doesn't? gotcha! Thanks. I was just asking things about this to undestand the differences. I'm not familiar with a 1010 motor. Is it actually a stroked 785? or a different block? They only made a few of those 1010's?

    Bow, you're talking about 2 different things.

    Mick said the SLX (1200) wasn't much different from the PRO 1200 except the hull.

    A PRO 785 and a PRO 1200 have VERY similar hulls, if not the same. Might as well buy a PRO 1200 VS. installing a 1200 engine into a PRO 785 hull.

    If you click the 2nd link I posted, it tells you the difference between the 1010 motor and the 785 stocker. More stroke, longer cyls, extensive machine and port work.

    That 1010 is a highly modified, gas valved, triple piped engine. It would easily beat a stock PRO 1200. Now if you triple pipe, and gas valve a PRO 1200, it will totally beat the 1010 PRO.

    Not sure of his top speed, but there was a guy at the Polaris gathering that had a triple piped PRO 1200. Pretty sure he's around the low 70's in top speed. (maybe someone can help me out with this) Snowman gave him props for keeping up with his modifed and supercharged SD. (for a little bit at least)

    You want 70-80's on a Polaris? You better look into a modified MATRIX.


    You better figure out a way to liquid cool a HD motor, otherwise you'll overheat or catch fire pretty quickly.

    You're better off trying to install a V6 into that hull, like that other guy did.

    I see the difference now. thank you for explaing it to me.


    Now could you take a 1200 pro engine and put a big bore kit on it and keep the gas valves and triples? 78 mph on glass? 12-vein pump or 8 or 6 ? Maybe some other brand pistons like a kawi-....?
