Best power plant for a freestyle 750sx?

[FreestyleFreak]

Just like the title says.Whats the best freestyle power plant for my 750sx?

 

[djkorn1]

An 800?

Or are you talking about aftermarket parts.

 

[Corbearofskiing]

probably swap the motor out for a 701 with a bpipe and all the essentials,


then swap the hull out for a sj


haha. sry i had to.

 

[eastbay]

get a 800 in that thing i rode a few sxis this weekend an they sucked on power my sxr ripped way harder with a tall prop!!

 

[FreestyleFreak]

motor

So i should get a motor out of a sxr everything will fit right into my hull?Will 750 electronics work on the 800 motor?

 

[Crab]

Yes to all 3, but you can make the 750 hit just as hard or harder by letting Group K convert it to an 850cc.

 

[FreestyleFreak]

How do they do that?Bore it out and what else?

 

[aof13]

Big pin cases and crank
92sx cylinders.
Porting by ______
Single 46 carb

Factory wet pipe

skat prop (pitch depends on what mods you have)

msd enhancer or total loss.

 

[turbohatch3]

take it to the dealership and they can convert the whole thing into a superjet.:biggrin:

Yep get the superjet conversion and you will be on the water to freeride fun.

small pin crank and case (lighter) 92to94 sx cylinder with proper porting or stock Xi cylinder. ADA head ,dual 44s, wet pipe.if 93 then use advance plate.

 

[djkorn1]

The 850 mod by Group K should rip.

A stock superjet is a dog... :banghead:

 

[spxrider]

I haven't been riding long but my 750sx trys to rip my arms out of there sockets every time I pin the throttle. But I'm sure once I ride it for a while I'm gonna want more.

whats good about the ss-xi cylinder? I just got a 750 out of one for my x2 and was wondering how the porting is set-up.

I'm pretty sure the SXR 800 cylinder should bolt right up to your 750SX bottom end. I slapped an SXR 800 cylinder on my 750 SXI bottom and it bolted right up-no mods needed. I even used my 750 head. I have a SJ with a b-pipe and both skis are about equal in power.

 

[BlueBreadTruck]

or bore your 750 to a 780 (82mm) which is still within the stock bore sleeve limit and you can have the exact cc's of a 800

 

[sjetrider]

bigbor lamey superjet motor and a superjet pump

 

[FreestyleFreak]

sxr cylander to 750 bottom end

So a sxr cylanders will bolt directly up to my 750 bottom end?And i can use a 750 head?And a 750 crank?

 

[SuperJETT]

whats good about the ss-xi cylinder? I just got a 750 out of one for my x2 and was wondering how the porting is set-up.

The ss-xi is a different model, he's talking about the old Xi. There used to be a single carb SS and a dual carb Xi version, then later the Xi-R and SS-Xi.

A big bore flat top Yamaha 62T/61X setup would be the best freestyle power plant.

At least you will be using the Wiseco Kawasaki pistons. :biggrin:
