10 litres of petrol in 40 miles

[uglyworld333]

Hey guys,

Bought this 2008 zx6r from a dealer the other day (not official kawasaki daeler). It has 19000 miles on it, and I straight away noticed a problem with this bike (it was delivered, and I trusted the dealer saying that the bike is in good running condition, as I know I have a warranty and can return it anytime I want). At first the bikes revs would stay at 3k rpm when revved up and then go back down in about a second or so. So I took this bike to kawasaki dealer and they said they will probably have to balance out the throttle bodies. Now an even bigger problem has popped up, the bike did 40 miles of riding and used up 10 litres of petrol. I called kawasaki again, they said this issue could still be related to the throttle body balance. I will have them balanced this wednesday, but maybe someone here has any idea what could be happening with the crazy petrol consumption? I don't see any leaks on the bike, FI light is flashing but it's because the stock exhaust was removed.

Would appreciate any help. Bike itself runs okay, there is some black smoke coming from the exhaust when revved above 5K RPM, so I am assuming it is running rich, but no way it should be burning that much petrol. As a side note, I will be returning the bike back, if the problems are not fixed by sorting out the throttle bodies or asking the dealer to cover all of the costs.

Reject the bike under consumer rights act 2015.

So I shouldn't even bother trying to sort it out even if the dealer is willing to cover the cost? Returning the bike would waste a lot of my time, as I use it to commute as well, and the dealership is 200 miles away from me. Obviously I will be returning it, if it's something costly and time consuming to fix.

I wouldn't bother they're not a rare bike and to use 10l of fuel in 40 miles sounds like much more of an issue than just unbalanced throttle bodies.

Send it back, buy a non lemon.

Sounds like the coolant temp sensor maybe knackered, simple thing to let the dealer try . . .

10 litres in 40 miles? Is that roughly 70 miles on a full tank?
That's either a leak or significant over fuelling.
Either way it's not in good running order which is what you paid for. Send it back.

If it was me I might have a look at the state of the plugs to see if it is over fueling and check the throttle bodies, but if it's such a simple fix why did they send it out like that?

If I had to guess I would say that there's a hose or a plug off one of the sensors - the air temp sensor or (more likely) the manifold pressure sensor.

Hi there, will post the error code later on, but I believe that was already diagnose as butterfly valve by the local kawasaki dealership. The reason why I am not asking the dealer that I bought it from to carry out the job, is because like I mentioned they are around 200 miles away, I got my bike delivered. There is also a loud rattling noise with the bike, but as far as I know zx6r tend to have loud CCT noise, and the mechanics didn't find it strange. I was also told that by putting the bike on dyno, would show the possible issue, maybe I should just do that, so I have a proof there is something wrong with the bike? I'll probably end up not touching it though, and just asking for full refund + to pay for picking the bike up from me, because I read that they should cover those costs as well.

Question, can the dealer refuse to refund me for the bike for whatever reason? I haven't touched the bike and barely ridden it. The only thing that was done to it, was taken to Kawasaki dealer to get diagnosed for sticking throttle and the FI warning. I believe I should be refunded with no questions asked for a month?

Have you even spoken to the original dealer about these issues?

They'll almost certainly laugh at you when you begin asking them to cover other garages costs if you haven't already agreed this.
