- I've been having a ball on the 1990 Kawasaki ZZR1100.... Right up unitl last night when it started running on three cylinders. So this morning I'm trying to find out what the problem is and see if I can't get it fixed.

The Jam by Slynk & Mr Stabalina

I haven’t seen a ZX-11 on the road in maybe 10 years. Here in the US if it’s not the latest it’s junk. I love the ZX-11,great bike.👍🏻
I'm quite impressed with it really. Yes, the looks are a bit dated, butnits a fun bike to ride and plenty quick enough for the road 😁👍
Jamie's a good man being there and helping you out 🙂
We always have a giggle and playing around with biked is something we both really enjoy. He's a good bloke is Jamie 😁👍
Its funny that my Name is Jamie and I've just rebuilt my zzr 1100 D3 and Ive also just sorted my carbs. was over fueling due to float height problem.
The ZZR is still overfilled, but there's a few more serious things going on in there after the dyno runs.... 🤣
@@QuickBikes Yikes. Sorry to hear.
Im planning a full OEM restore on mine. Parts are tricky to come by in South Africa, but yea i try. Sad thing is with only 42000km on the clock ill need to do the head soon, cylinder 2 intake valve 1 is already on 2.90mm shim (max 3.0mm) and 2 valve lobes are pitted. Dropping valves aint fun.
Otherwise the bike goes like a bomb for now.
Also thanks for the video on the fuel pump relay, that thing had me properly scratching my head.
Best of luck with your bike matey. Parts aren't easy to come by here either and many bits are no longer made... 🙄
Could the carburetors (or something else) be slowly damaged over time from ethanol in the fuel, causing the engine to run rough?
I don't think any ZX-11s (Cs or Ds) were designed and built (in the 1990s through 2001) for today's fuels containing ethanol.
Just something to consider...
Nightmare, my money is on a coil related issue. Hope the fix is not too expensive and looking forward to the solution.
Niggles like this were always to be expected really as I just assumed things like coils etc were all good. I only serviced the stuff that was obviously knackered... 😁👍
Nice! What lovely convertible bike its a four... And a TRIPLE!! Awesome!!
Sounds betterer as a four though 🤣😂
Bummer!!!, ZZR1100, would need to be very very healthy, to fully Enjoy it. I had no bike Kawasaki for 27 years, March 19 got a 05 very very healthy Bandit GSF 650inj.?, Enjoyed it a lot more than my nearly new Kawa.750 turbo '84, Couriered on it, Thrashed it Daily Countless times, Lovely but Bandit Time Times,? So so Special.
Basics, there are three things required for combustion, compression, spark and fuel. It would do no harm to run a compression check now the rings etc. have bedded in. An inductive timing light is a good way to check for ignition faults. Before hauling the carbs off it's worth checking the seals by spraying brake clean (or similar) around the inlet to seek out any possible air leaks, especially as Jamie thinks the affected cylinder is running lean.
HTH
Thank you matey. Only trouble is I've pulled the carbs off, cleaned them and checked the coils today 🤣😂😅
A compression test is a good idea though 😁👍
My experience is from the D-models, but they should be similar enough. Two notes:
The cylinders are numbered left-to-right, so cylinder 1 is the leftmost one.
They need the restriction of the air-filters, or they'll run lean as heck.
Yup, I've been corrected on that one regarding rhe numbering. It doesn't really matter in this instance though as it's a wasted spark set up. Good point about the air filter as well, thank you matey 👍
What finally happened to the zzr1100..is there a finish video
It's sat under a cover at the minute. Basically I should have run it in for konger rather than just sticking it on a Dyno after 500 miles. Once I've got some other stuff out the way, I'll get back to it and get it sorted 😁👍
Hello Quicky, I would check for a spark again on both cylinders 2 and 3 as I think it's the plug lead/cap. Swapping them over will still give the problem, just that the other cylinder will be not firing. Could check the spark on 1 or 4, is it as good as 2 or 3, that might also tell you something about the coils.
I'm not convinced it's a fuel issue.
Yeah we did this but the camera wasn't filming.... I should have said. The coil measures a bit off do it's just getting replaced. It can't hurt to Di so in my mind.
Please check the routing of the carb vent hoses with the manual, I seem to remember I had a similar issue which ended up being a blocked (pinched) hose, first I thought it was going to be spark plugs especially if the are ngk and bought from eBay, so many fakes around, I only buy my plugs from decent shops/motor factors now. Good luck Rich
Thank you matey, will do 😁👍
The coils have two outlets, had similar issue zzr1100c2 found hairline crack on threaded section on the outlet on coil 2. Eventually fitted stick coils and loom from a ZX9R been reliable since. Best regards Chris.
Oooo... stick coil upgrade... I like the sound of that as you can't get these ones OEM any more.... 🤔
@@QuickBikes no but they come up on ebay. 60 to 70 and 20 for loom, this needs altering but is easy to do look on forums for conversion info, bit busy with my beer bottle at the mo but will look and send link if I can find it again 😀
Awesome thank you dude 😁
You've only had it together 5 minutes and you've broken it already! 😝
Hehehe.... 500 miles ain't much really is it 🤣😂😅
Hi Quickie, stumbled on your channel and am loving the reality of it, I am currently restoring a D3 95' but your scaring the crap out of me!!! I am probably 2 months off finishing but will send the before and after shots... Are the marten shirts available to purchase? Cheers Mate, Paul
Geddon, that'll be another one back on the road before long then 👍
I pulled the Marvin shirt a while back, but will be putting it back on shortly. Keep an eye out on the TeeSpring store 👍
What type of fuel do you use? I use only 98 V power from Shell because it got no ethanol in it. May be your problem is there. I have problem with lawnmover and everything who get on gas with carburator on it. Ethanol plug the jets
It's just Super Unleaded whatever that is, but I don't think it rhe quality of the fuel as the misfire was quite sudden and definite... 🤔
The fuel filter should have caught anything rusty from the tank. Highly unlikely rust got as far as the carb. I would check the fuel filter for blockage anyhow, but that wouldn't cause a problem specifically with only one cylinder. However it may already be close to clogging and causing more future problems if you just cleaned the rusty tank. I cleaned a zx9 tank and my new filter got clogged very quickly and needed replacing after one day. Turns out I didn't get all the rust out of the tank and had to clean it again. You should probably consider changing the jets since it is apart and you say it runs lean. One of my zx11s has a left side muzzy pipe and dyno jet 160 mains, mixture screw 2.75 turns out. 155 keihn mains and 1-5/8 turns out is stock in california. UK may be different. 155 jets and 1-3/4 turns out in UK I believe??
Thank you matey, that's very helpful. I know thr jets need changing and was going to do a dyno run to get an AFR graph, then monkey with the jetting and doing another dyno run etc. Now I'm considering getting a stage 2 dynojet kit as that should be pretty close to what I've got.... hmmmmm..... 🤔
I thought as you said first not the plug . I've had new plugs fail withing 5 miles and ten minutes ... it's got ya grey matter going so I'm gonna say if not plugs then itll have to be fuelling could it be a loose jet or shite ..we shall have to wait n see .. laterers
The next video is cooking as we speak matey 😁👍
Nat had an intermittent problem with a cb 400, turned out to be a plug problem, nats Nackers Yard 😉
There's not.much needed for an engine to run really, but you can end up chasing your tail trying to find the problem 🤣😂
Seen a few ZZR's with fuel consumption issues, if that was your problem check the float seat o-rings.
Yup, will do. It was a brand new service kit with a new seat and valve included, but always worth checking hey 😁👍
Have you tested the compression?
Not yet, butnits been mentioned in the comments and will be getting tested as well matey 👍
stuck open needle valve the new fuel is so dry makes them stick just a little bit of two stroke oil in your fuel makes them behave brush the spark plug it would have fowled from running rich my bike I put new new carbs ,coils leads 6 sets of plugs still did the same thing . an old fella told me to put a little bit of oil in fuel haven't had the problem since
Ah right, I've not heard of that one before.... 🤔👍
Happy midsummer from Sweden Quicky! /HM (the Busa rider)
Thank you matey 👍 😁
You to dude
@@QuickBikes maybe convert this to fuel injection or if there is problems in the future? Seen people do it with Blackbirds and ZZR using Hayabusa throttle bodies and injectors
Ah right... and some sort of ecu etc... I may look into it, but normally once carbs are sorted you can just forget about them I've found... dunno, maybe 🤣
@@QuickBikes Yes, and the loom. But I guess you need to put triggers and sensors to the cams etc. I think you have enough tools though....Here is one video I found, but I don't think the Busa dash fits in a matter of taste 😁 ua-cam.com/video/9D1dbFROoms/v-deo.html
Good bit of fault finding 😄. Surely from your testing we have to believe the electrics are ok. People have mentioned about numbering the cylinders incorrectly but if it's the middle two cylinders that share the same coil then it doesn't matter if it's 2&3 or 3&2 👍. I agree, some sort of carb issue/air leak issue. Is there a drain screw on the float bowls you could get to? Just to see if there's the expected volume in the bowl for the dodgy cylinder compared to a good one. That's my two cents 🤣. Good luck.
You're thinking along the same lines as me matey. As for the drain screws, I can't get to them with the carbs in place which is a shame. I was hoping to find bugger all fuel in it as a cause of the problem... 🤔
The zzr lovin' Busa rider 😁
Hehehe
Hi how are you I know this feeling well it was corrosion on a jet a simple manual cleaning.
I really want to see you out there showing that beautiful girl off hope to see you tomorrow
Once its properly sorted its getting g some miles put on it and I'll take the cameras along as well. There's a cracking oast road round here 😁👍
Niggles like this are kinda ro be expected though as it was a straight up assembly job only servicing the stuff that was obviously knackered 🙄 😁👍
Simon....,Carbs and Cylinders are numbered 1,2,3,4 from 'left to right'...
(Your HT leads should be labeled with little coloured tabs and fitted accordingly...)
Have you got the plug leads 2&3 mixed up and fitted incorrectly...?
Switch over spark plugs 1& #"3" which is the pot it is off...(Not #2)., to see if it is a bad plug...
A bad plug is obviously an easy fix if that's the problem..
If not, my money is on a blocked pilot jet...(they are fairly susceptible...)
Very rare for a coil to go bad...(similar to ZRX's)
.......but be 100% sure of your plug lead sequence...'left to right'...1,2.3,4.
Oh, and you could also take the lead out of the cap on #3 and trim 10mm off then refit it to be sure of a good connection....
BG.
Cheers matey. The coil feeds cylinders 2 and 3 and its basically a wasted spark setup from what I can tell, ie both spark plugs fire at the same time but only one cylinder is on its power stock, so surely it doesn't matter if 2 and three have been switched around. I think I covered it in the video where we swit he'd rhe plug leads around and got the same result matey... 🤔
Hi Quickie, not relevant to this video, but I think you should replace the screws holding the number plate on with Black ones, I have had to do this on my bike. :)
I was thinking along the same lines as to be honest I didn't have any and just robbed these off ASBO's old bodywork 🤣
Option c looks best
Thank you matey
fettle .. fettle.... did a jet come loose? had that on a zx6r g2 - it was laying in the bowl! cheers. :)
There's going to be fettling required as I didn't build everything from the ground up... I only serviced the stuff that was clearly buggered and just assumed coils etc were all OK. The fork seals are a prime example 😅
Have u found the problem , carburettor
Kinda.... the next video is just cooking as we speak matey 👌
❤
👍
😁
Yes I find it strange how u no. The cylinders right ( as u sit forward on the bike) to left 100 percent every manual I’ve ever read goes left to right. But I think I saw u reading right to left out the manual or is it I live in the land down under and it’s done back to front 😂
It doesn't really matter as this is a wasted spark set up anyways, so both plugs (2 & 3) that are fed by the same coil both fire at the same time... 🤔
Mine ran like that and it was the coil.
These definitely are measuring a little bit off... it can't hurt to swap them though hey 😁
Do comp test on 2
Yes matey, it's on my list of things to do 😁👐
Check for fake NGK plugs !!
Hehehe.. plugs are fine matey and have been swapped around 😁
without watching the vid ...sounds very fuel y lets see if Im right hahhaha!!!! and at 6.27 Im wrong ! ( Ive had plugs that LOOK and test fine but under pressure fail,, try a working or new plug ) or sell it and buy a Royal Enfield ,,, electrical faults are "sudden" carbs are full-time dependent on the circuit, 1 change at a time it sounded like the cylinder wasn't getting fuel, does the cylinder "pick up " when u squirt a bit of wd40 down its throat when running have u swapped a known good plug into the cylinder ? or swapped coils over ( not just leads ) resistor in spark plug cap failed ? . The problem disappeared when you moved the wiring swapped leads but came back when put back to the original position, so you "disturbed something" compression test ( just to check basics ) but a known good plug in cylinder 2 , test ,,, swap coils over not just leads , when running move wiring, HT leads around see problem "changes " ..... be very interested in the outcome !
Carb dirty
Not so much matey... 🤔
Mine did same thing if you let it sit and then it runs good for a few minutes then does it again ill put money on pilot jet picking up specks in fuel bowl
Yeah, they all got cleaned out in the end but to be fair the carbs were fine...
