Hesitation and cutting out

Hi all!

I'm Scott I'm new to the forum and to the world of biking...

I have owned my 1998 ZX6-R G1 since June this year, and since buying it has had a slight problem and I don't know what is causing it...

I've tried using the 'search' function and can't find any advice that seems to relate directly to what I'm experiencing.

Basically the problem is, when you 'blip' the throttle on the bike the engine stalls. Before anyone asks I am allowing the bike to warm up fully. But even after a good ride this happens. Also, if I don't 'blip' the throttle, but turn the revs on slowly, the bike hesitates for a second then the revs build up very aggressively after that?

The bike idles fine and otherwise runs very well and starts first time, but as said if you rev it too quickly it dies, rev it sensibly and it hesitates then does go.

It may be worth mentioning that there are exhaust gases leaking up from the right hand fairing which I assume to be a crack or something in the exhaust however have not got roiund to investigating. May not be linked but I thought it would be worth mentioning.

Any advice greatly appreciated!!!

Thanks in advance...
Scott

carbs probably need cleaned. I would find out about that exhaust leak ASAP as well.

I will have to put the carbs on the winter to do list I think, a clean and balance.

Should I be worried that the exhaust is leaking? I know it needs seeing to but I didn't think it was such an urgent thing?

Thanks again for the feedback!

Scott

if you know for a fact that it is only just a small crack in the exhaust or a bad gasket then its really a non-issue other than being annoying, but could be something much more serious, hence why i advised that you should check it out ASAP.

Amazing! I havent been on the forum for a while, I logged on today because Im experiencing the exact same issue. I dont have the luxury of putting it on a to do list because i need the bike for commuting.

Weather permitting Im gonna try and sort the carbs out tomorrow. Watch this space loadofkwak and I'll let you know if it works for me.

Hey Chris, sorry to hear your experiencing problems with your bike, but if you do manage to sort it out it would be much appreciated if let me know! I plan to have a look at mine this weekend, so I will keep yopu posted on this thread.

With regard to the exhaust, I will give it a quick gander whilst the fairing is off, if there are no obvious cracks or leaks...what else could it be Mr WildCard?

Again advice greatly appreciated,
Scott

Headgasket, warped head, cracked head, etc.

Ive looked up a few tutorial vids for cleaning carbs and while it should be fairly straight forward to do myself, getting the bike somewhere dry is going to be difficult. There is actually a garage right next door to me that I can use, if I can just get the bike up the hill. I will let you know as soon as Im able to get the bike home and have the time to get down to it... for the time being I'm walking!

Well its taken me a lot longer than I wanted but I finally solved the problem and the bike is running sweet again. The problem was water in the fuel tank!

I'm not entirely sure how that much water got into my fuel tank but Ive unclogged the carbs, blown through them and hey presto im back in business!

That could well be what is up with mine and I'll tewll you why...

The fuel tank breather pipe had a kink in it. it wasn't running straight down in line like supposed to, so any water getting past the filler cap was building up and instead of draining thorugh said pipe it was going into the tank.

So I now need to drain the tank (and the 20 soddin quid of fuel in it ) and the carbs.
