Kawasaki 1200cc engine fuel economy
A question about the Kawasaki 1200cc engine, (Ultra 150)...
What is the fuel economy of this? Both at WOT, and just crusing.

Ultra 150... 7.8 gph @ 40mph 11.3gph @ WOT
STXR........ 8.2gph @ 40mph 11.2gph @ WOT
Not sure on tank size of ultra but I think it's 14.2 which is what I have but in 2004 the stxr got a 16.2g tank
Hope this helps

The fuel economy of that engine is horrible 1200cc, triple carbed two stroke, need I say more. I have the stxr and can only go 60-65 miles no matter how you ride, it really doesnt matter how you ride at 30-40 your not saving any fuel. I ran mine dry once and it came out to 3.6 mpg and thats not even killing, im willing to bet at WOT you would prolly last 50 minutes.

The Ultra tanks is 15.1 I think. I know it's 15 something. Really for a two-stroke with that much hp it does pretty good. The CV carbs are the most fuel efficient carbs you can get on a stock ski. If yo are concerned about gas then you shouldn't be looking at a muscle craft.

Thanks guys...I'm actually looking to upgrade possibly to a larger ski (250x)
I know the 250 GUZZLES fuel, and I'm also aware the 150 isn't the greatest as well. My biggest concern about the upgrade at the moment is the fuel of the larger ski. if the 250x is only going to use a a bit more than what i'm currently running, I might as well upgrade.

The stock fuel consumption on the ultra 150 isnt so bad. I find that i can ride almost the whole day on one tank. Thats if im on plane most of the time and not plowing at low speed. I do let it rest once in a while. However that will change now that i upgraded the entire fuel system basicly. If you want fuel economy one of my frends has a honda turbo two seater and that can ride an entire day on half a tank of gas.

I want both power, and the ability to take a passenger along (comfortably). The 150 is great, it gets alot of negative attention because of it's weight, and hull design. I enjoy it, it takes skill to ride a smaller machine. But with a passenger on the back, it's a real chore to keep balanced at low speeds.
It's just that it's also fun to bring someone along with you from time to time when you're not racing around. The 250x and 150 are completely different breeds, (2 stroke vs. a Supercharged 4 stroke) But if the fuel economy isn't much, much more from a stock 150, to a stock 250x, I wouldn't mind an upgrade, you know?
I've seen the kawi 12 and 15f's and no offense to the guys who own them, but i think the styling of these machines was not well thought out.

For a 20 gallon tank on the 250X....it also only lasts about 1 hour @WOT...
