Only reason I'm modifying it is because it's my first ski so it's more of a nostalgia sort of thing. I'm going to save up during college for a 310 and then I'm going to do the same sort of mods to it.

Hi,

I'm looking at ways to make my 250 more of a 1 seater than a 3 seater just to force my friends to not try to ride on my ski, especially because I'm going to be modifying the hell out of it so...

Hi,

I currently have basically every Riva product they offer for the Ultra 250 on my ski, and I'm going to put some more mods into it and wanted to get some opinions. I'm going to put the...

Hi,

I plan to get a 300/310 over the winter so I can have a more dominant ski than my current modified 250x. I wanted to reach out here about modding because I'm still new to the modding community...

Hi, I was riding my '08 Ultra 250x with a friend on his 250 and I was at maybe 45mph or so when all of a sudden my ski died in the water. I restarted the engine and tried to give it full throttle and...

Thanks for the reply,

I'm thinking of keeping the 250 as long as I can as my high school toy (I'm 16) and I'm going to try to get another ski once I can afford to get one (probably a 310r now)....

Hi,

I have a 2008 Ultra 250x and I'm struggling to narrow down what mods I should install next to get top speed in that aren't too crazy and easy to do for an amateur. I currently have the Riva...

Will it jeopardize any of my stock internals?

Hi, I'm looking to get an ECU upgrade for my 2008 Ultra 250x, I have the Riva intake, breather, and exhaust kit, and plan to get the waterbox, solas 16/21 prop, kawi pump upgrade, and bov blockoff....

Hi,

I have a 2008 Ultra 250x with a few mods already installed: Riva Air Intake, Riva Engine Breather, and Riva Exhaust (no waterbox). I should tell you that I primarily ride in lakes but I do...

I still have the throttle body hose connected to the airbox as I don't have the power filter kit installed. I would install it if I didn't have to basically remove the glovebox because I plan to keep...

Will removing the box increase power or is it just a good idea to remove it?

Hi,

I've recently installed the Riva Engine Breather Kit for my '08 250x and I have a question. Is it possible to simply remove the oil catch can air hose that comes from the air filter and just...

Hi, summer is just around the corner and I've been searching for performance parts for my ski but I'm not really sure what I should get. I'm looking at the riva performance intake kit, free-flow...

Something I should add is the fact that the previous owner (we bought it used) left a rag of some sort in the engine and when my friend flipped it over once, the rag fell into the driveshaft causing...

Is there a way you can link me to the 300 pump upgrades I should look into?

Thanks for the reply. Do you think getting a new prop/pump would fix this problem? We’ve done a lot of work and spent a lot of money on my ski to make it look brand new so I don’t really want to get...

Hi,

I'm still new to the whole Jet Ski life and have been dealing with a few issues in the past year of owning my 2008 Kawasaki Ultra 250x. My ski is 100% stock (for now) and I've noticed a few...
