Bogging down?????

Hi guys, second day with the Z1000, not bad at all, I need to tune the suspension to my style of riding. And this is my main beef with the bike.

After using half the gas in the tank, the bike starts to splutter loose power, like the fuel has ran out. I have to drop the RPM'S to around 3,000 RMP'S before the bike starts to pick up power, then the same thing accures, it's acting like the fuel has been cut off only droplets are getting through. I would rule out the jets, only because when I refuel, the bike runs like new. Any insight? would be welcomed. Cheers

I havent a clue. Id go burn off half a tank of gas, get it to start running crappy again, and then drive it directly to the dealer and ask them WTF?? That just doesnt sound right.

Another thing that doesnt make sense is how you wrote this up...you say that you have to drop the RPMs to 3K before it starts picking up power. Are you running it in 2nd gear at 10K RPMs constantly or something?? Are you breaking it in properly?? The bike naturally makes a lot of low and mid end power - so its tough to say what it is...

Good luck bro!

is it a 2010? also did you buy it brand new? theres a few things i can think off at the top of my head. first thing is bad gas. i know it sounds weird but i experienced it myself. if you get gas at the same place all the time run your tank on near empty and refuel at a different gas station. another is it seems like something is clogging your fuel system. the fuel system has an easier time of getting gas whenever its full so it makes sense that when youre at half tank that it starts bogging. last i can think of and very unlikely is your fuel gauge acting up. you might think youre at half tank when it already might be empty.

Hey thanks for the insight. I have an 04 it had 970 miles ran fine the first day, rode around 140 miles on a full tank of gas. The next day I filled it up and rode until just below half tank when the problem of lack of power, also un smooth throttle pick up, (slight hesitation) I was new to this bike so I just thought it was me to hard on the gas. Then I thought it might be bad gas. I add fuel injector cleaner and filled the tank once more and the same thing accrued. I think it's a vacuum issue, due to a slight clog. Any, I'm going to pull the tank off and check the fuel pump and all the hoses.

Thanks for your help, I will post my results.

Regards, CANONFUJI.

I did the dealer tour, He was talking $400 to $500 and did not mention any thing about a simple problem, like a clogged hose. So I'm new to this bike and Kawi. I do all the work on my Yam fz1000 it has 90,000 miles that I have put on. And I got plenty of help on the forums, so the dealer is my very last option.

This bike is an 04 not from the dealer, but they did do work on the bike before I picked it up, first tune up only 970 miles.

The rpms drop due to pressure build up, that's what I think, demand for more gas and can't supply it fast enough. Any thanks for you help.

found the problem.

Content of my gas tank, which I did today and man oh man, I took the tank off the bike after emptying 95% of the gas and removed the fuel pump and there was around a small hand full of rusty metal flakes sitting at the bottom of the tank. I took out a wet vac and was able to remove 99% of the particles.:confused: I don't know how it got in the tank, I would say some one dropped some thing in the tank a long time ago seems the bike is an 04 and only had 970 miles on it when I picked it up 3 weeks ago. I picked it up for 3,900 yes a good price, but there's always a ? when you buying way under market price.:rolleyes:

Any way, I put it back together and started her up, then I noticed gas gushing out of the rear of the tank. The gas lines have dry rot. So not able to test to see if it was the only thing effecting the performance. I would say it was. :eek:
