i had steve at watercraft factory bore my carbs. however, my engines are freestyle ported, not race ported. your results may differ.

SHHHHH!!!! dont say the D word around here!

you dont need to try one out. YOU WANT ONE! okay? i mean, how could we ALL be wrong????

:haha:

it 'could' be just your seals and bearings. but if the rubber separated from the metal (like a motor mount comes apart), its time for a new housing. they are meant to be rebuilt as in bearings and seals, but if the housing, itself, is bad, it go bye bye. you will, at least, have to move the...

even a 650 SJ would be a vast improvement on the 550. you could score a cheap 650SJ and slap a set of 701 cylinders on it later. unlike the early kawis, yamis stuff is pretty much all interchangable between the 650, 701 and 760

i put a bored-to-48mm stocker on my wifes 61x case. i opened up the stock manifold to match the carb and cleaned up the huge lump that sits right below the bore and remove a lot of other excess metal in the manifold and it made a huge difference. im using an identical carb on my 62t case and...

a race ported motor would yeild less brap that a freestyle ported motor and probably even less brap than a motor with stock exhaust port height.

take THAT, you waterpigs!

under $1000 pretty much leaves you with '90 - '93. they have the 650cc engine. its possible to find a '94 or '95 for under $1000, but not very probable. those have the 701 engine. all of those years ('90 - '95) are known as square noses. the '96 to present are round noses. typically, a bare...

:cheer: much better! screw the action shot. you need to replace it w/ your new SJ!:biggrin:

IMO, a kawi 650sx is a step back from a 550. definately an SJ.

more than likely, youll need a whole new housing, seals and bearings.

wouldnt the stocker be the best for keeping water out, like on a sj?

a SJ will tow very easily with a 2' rope. to keep it from slamming the rear of the boat when you slow down, maybe a foam noodle around the rope.

jetskimermaid (i think her name is on here) works at UMI. maybe she can help ya out.

youd get better results running the stock impeller with the stock pipe.

SXR uh, i mean superjet!

wow. it must take a lot of balls to come out of the closet on a public forum like that.

www.watercraftfactory.com just ask pancake pete and pat bogart. .....and me.... :haha:
