My kawi (Ultra 250x '0 has riva plate, riva free air-filter, riva free riva exhaust, riva sponsons, tbm scoop, r&d anti-cavitation cone, and impeller skat-trak 13/19.
..After the last service(55hours) my kawi has lost acceleration and top speed(54mph)!! It can not reach more than 7-8psi in the boost meter and it has dificulty to overtake 7000rpm but outside the water it works normaly.
In the last service I changed sparks, oil, oil filter, sc belt and sc oil and I installed skat-trak 13/19 SK557520SW1319 and r&d anti-cavitation cone.
I already checked oil level, belt, sparks, fuel quality and sc.
Is the problem in the impeller or in the anti-cavitation cone or in anything else?

Hi all ,
First time here ,can any body tell me what the first ten hour service is ,
can I do it myself ,if so what do I have to do and or change please .
I have had ski ,s before 15 years ago, and worked on it myself , but had to sell sadly from medical con .
Any help would be great .

So......this is it. I have sitting in boxes the Riva free flow exhaust, the pump shoe kit, the OCMS kit, a 6 degree timing key (thanks to Rudy) , the BOV block off, and the emission by-pass and all the parts to do the I/c reroute. On order is the R&D ride plate. Impros is doing a Stage III speed mod on the impeller and flowing the pump and putting in new bearings.

I do not have a large amount of time to actually do all of these myself. So during de-winterization, I will have the dealer do the OCMS and the timing key. I do hope during their spring inspection that when they do the compreesion check it will come back to warrant new pistons/pings and they will be more than obliged to use the 09 set. I still ave 2 years left on the extended warranty, so we shall see.

Cosmetically I will be removing all the factory annoying decals and putting on a few performance ones.

As I begin this project, I will take and post pics as I can. WIsh me luck to achieve 70!!!!!!!!

Hooah,,,,,,...

ok this is what my engine looks like right now. I have the 09 parts on order.
