    Needing Performance parts for 2007 Ultra 250x

    Hi all I'm desperately chasing some performance parts for my ski, it's an 07 Kawasaki Ultra 250x, it's currently already got an R&D intake grate and Riva Ride plate. Cheers guys.

    well mate sorry to be so blunt but the best performance part for your 250 would be get rid of it and buy a 300x then you wont need to buy any performance parts and have a stock ski that will outrun any performance parted 250 dont wast eyour money the gains are just not in the 250.

    I have an 07' with the complete r&d stage 1 minus the intake grate and added the riva exhaust. It was about $1500. It helped but still won't out run a 300x. Honestly I would do exhaust, intake and emission block offs or let it alone or get a 300x. Keep in mind u have one of the sickest skis out there and NOONE will touch you in rough water the way it sits

    I think it's funny when people say a no matter what you do to a 250, a stock 300 will still outrun it. I'm still stock class legal on my 250 and I holeshot with the 300's and pull away from the SCOM'd stock 300's too. It's more about knowing what you're doing than just throwing money at it.

    i find that hard to believe on a stocker..like you said there is more to it knowing what you are doing, the 300 rider you can holeshot is obviously in this class

    Just ask GL, he's seen first hand what my ski can do. And I'm not quite done yet.

    What exactly are you looking to get out of your ski, top speed or good hook up?

    I will agree with you on that one, have both. Modded 260 and stock 300.

    My next experiment: Taking my 260x's 155mm pump and fitting it to my 300........mmmmmmmmm. I'll repitch my skat later if it needs to. Just for the hell of it.

    I'm willing to bet you'll just bounce off the rev limiter like crazy, plus a lot of cavitation out the hole. When I was testing my different impellers, I threw on an lx impeller just to see where it would get me. I was running 45 mph on the rev limiter and couldn't take off unless I feathered the throttle. It was a 90 hp difference for the impellers tho. But if you can get the pitch right, you can really pull some speed with the 155mm pump.
