ZXR 400, L9 - Is it all about carbs?

Hi All,
I'm new to this site (and excellent it is, so well dont to the inventor)! I too was going to post a message about carbs as my 400 2001, occassionally cuts out or I rev it like hell at traffic lights to avoid it doing so! I've had them cleaned and balanced, changed to standard NGK spark plugs and its a little better - but I still have a feeling it is a little rich.

To avoid any major stalls I run it with the choke on for approx 2 minutes, then half choke for a minute or so, is this usual practice?

Plus where I can I do much maintenance work myself, (whether it being car or bike), I did have a look at changing the plugs etc, but then decided against it so took it to a mechanic, mainly bcus you have to separate the fuel tank - is that true, or was I doing something wrong, no engine prop up stick?!?!?

One more thing I cant find a brake disk lock to fit and I'm on the search for a bike clock, (simple stick on) - any ideas?

Thanks in advance!
Mr P

P.s.Forgot to say, I'm back on a bike after almost 12 years, got married had a kid and now I feel born again!

Your missus will luv ya for that comment :smt005

Clock - corner shop , 99p LCD watch , remove strap , double sided 3M sticky foam & jobs a good un + cheap :smt003

I find some of my poor running especially coming up to lights etc.... is the terminals drying out under the tank - gets darn hot on there.

Pulled into suppliers yesterday and it started running on three - needed to keep it at 2.5K to get it running :smt011

Off with tank , pulled all the stick coils , unplugged the spades and reconnected everything , tank back on and vroom ! All four again confuddled

So next purchase on Saturday is going to be some dielectric grease and all the HT side of the bike is going to get lubed up , the strage thing was after pulling everything and connecting it was noticeably smoother and went utter bollox stellar to the redline :smt003

But it's been over 2yrs since the build and well over a year since I done the stick coil conversion, guess I need to have a poke about a bit more regular , that will cheers the missus up :smt002

Fuel tank has to be removed to change plugs! Where do you think they are ? :pmsl Easy job and while your at it ge a uick release connector for the fuel line and install, makes it easier next time around. :smt004

Welcome BTW,

MM! :smt001

Hello and welcome, ive used a Motrax big ben clock for time keeping, but as MoriMan says, any watch will do with a bit of double sided on the back.

check out some of our guides if you want to get stuck in with a bit of DIY - http://www.zxrworld.co.uk/zxr400/workshop.html

But there are countless threads on the basic stuff on the forum so make use of the search feature ;)
