SX/SXi/SXi Pro 750 sx carb

[kass727]

hey i have a 750 sx that i just rebuilt the carb on. stupid me i didnt take note of my high and low fuel settings. when i tried the recomened stock settings like the manual says it will not maintain an idle. i have to adjust the low to 3 or so turns out just to get it to idle nicely, and the high to around 2 1/2 turns out. it seems to run really good like this but i dont want to be doing more damage by haveing the settings off. does this seem about right for the. it has a coffman raceing exaust, jetted carb, primer kit and stock size forged pistons. idk if any of that would affect the stock carb settings and i dont wanna end up doing more damage to my engine.

Also can anyone recomend a good set of reeds that would increase my trottle responce.

42mm CDK sudco if you wanna stay with Kehin which allows you to use stock manifold. Or go with a Mikuni SBN 44/46 but you would need a new intake manifold

post your jet sizes.
when you say "jetted carb", was carb rejetted to larger jets for the pipe?
more info would help

im not sure what the jet sized are, bought the ski from some one and they said it was jettted when the pipe was put in. is there any way that i could check the size.

ya pull the cover off, not the fuel pump side but the thin metal cover and you will see your jets there

if i were to replace my carb with a 42mm would i have to rejet it? also ware would i be able to find a new kehien 42mm

you have to jet any carb you will put on/ jet for most engine changes. I think you can still find some brand new 42mm cdk

do you think this would be a good upgrade for my ski? will it make a noticable difference?

also i tried to look up the pipe that i have so i can find the proper jetting for it, but have not been able to identify which coffman pipe it is, it doesnt look anything like the ones ive come across. sorry for the crappy angle of the pic its the only one i have right this sec.

email coffman and ask them which pipe it is and if they have jetting
