Chrissb6 Posted December 1, 2015 Share Posted December 1, 2015 Hey Chris, I replaced the plugs a while back they had a very thin white covering (not crusty like in the bottom left picture in your link) which I think means it's running a bit rich? The plugs were all in good nick otherwise.Glorian I am outraged you can't be bothered to read the very very exciting thread about all the crap my bike has been doing White or brown Mate? White would suggest the engine is running lean. A blackened plug would indicate the engine running rich as in the pic's Quote Link to comment Share on other sites More sharing options...
Hoggs Posted December 1, 2015 Author Share Posted December 1, 2015 White would suggest the engine is running lean. annnnnnd this is why I need help Yeah defo more white than brown. I think I still have them if visuals required! Quote Link to comment Share on other sites More sharing options...

I think I still have them if visuals required!Be good to pop a pic up, I would not go any further than getting the fuelling and carbs check over. Could be something as silly as a dirty fuel filter or blocked fuel,vent or vacuum pipe if all the plugs are the same colour. If one of the plugs where a different colour then that would indicate issues with that individual cylinder you have already said the coolant and oil is ok and I'm assuming no rattles. So look for the basic's faults first before being sucked into open surgery. Quote Link to comment Share on other sites More sharing options...
Chrissb6 Posted December 1, 2015 Share Posted December 1, 2015 The more l read into this the more l suspect a weak perished vacuum or fuel pipe or pipes. The pipes will be fine when cold but once the engine warms and up the heat radiates out to the fuel - vacuum pipes this will make them go soft causing a partial collapse and your issues.

Matt Strange Posted December 7, 2015 Share Posted December 7, 2015 the throttle isnt electronic controlled its wrist controlled tps would be in a fuel injected bike Some carbed bikes do have a TPS, this one and late model mk1 blades being two i can think of. I did mention the throttle is cable actuated earlier in the thread. Quote Link to comment Share on other sites More sharing options...

The pipes will be fine when cold but once the engine warms and up the heat radiates out to the fuel - vacuum pipes this will make them go soft causing a partial collapse and your issues. We ran it up to temp and (with gloves on!) gave the pipes a squeeze and they seemed to be holding up ok but only checked the ones I could access with the fairing off. I've had a whole tank of redex'd fuel go through now and on to tank 2, it does seem to be running better (I am aware I have just cursed it....) no backfire or wild idling fluctuations at temp when stopped. So gunky carb floats a possibility? She is quite old bless (2001) and as people have mentioned possibility of lots of small issues randomly flaring up. Only done 15k so maybe been sat around doing nowt for long periods!I'm a complete noob so appreciate all the input (that I then read up about in the ole Haynes manual so at least I know where all the bits are and how to get to them!)

Scud Posted January 13, 2016 Share Posted January 13, 2016 I've read the whole thread, no ideas as to what's up, but as I have a J1 zx6 that has a knackered gearbox, I've got a replacement engine that I'm needing to put in sometime very soon, I've gained lots of info as to problems I may find. Thanks for the inadvertent help Hoggs! Quote Link to comment Share on other sites More sharing options...
Hoggs Posted January 13, 2016 Author Share Posted January 13, 2016 Haha you're welcome! Been running redex through for a couple of months which seems to have fixed some issues. .. only backfires when it's really cold now! It also has a stupidly high idle from cold on the choke (will be fine at 1500 for about 20 seconds then shoots up to 3000 turn choke down slightly and it's fine...)Although on the way home there was a clunking sound... had a check round and nothing obvious but I may be starting a new thread soon!

Scud Posted January 13, 2016 Share Posted January 13, 2016 They do that choke thing, I had a m reg one years back, it did the same, and the head gasket did go on that! I'm sure there will be a few sweary words and threads from me as I swap the engines over, then it will get thrashed as hard as possible on the track by way of punishment. I've not actually riden this bike, I bought it cheap as a track bike (it's road legal though), my father in law has used it and I had to use my gsxr, then the gearbox went and he bought a gsxr600 for himself and left me with the repair!

eastanglianbiker Posted January 13, 2016 Share Posted January 13, 2016 engine swap isnt to hard a job to do one of the worst bits will be getting all the exhaust studs undone without shearing any off not that it mater as the engine is being changed but can lead to skinned knuckles as they shear lol Quote Link to comment Share on other sites More sharing options...
Hoggs Posted January 13, 2016 Author Share Posted January 13, 2016 Thanks JRH! hopefully it's something silly like crud caught under the hugger.... Well good to know the high idle is "normal" but if the head gasket goes I may cry. I'm rather attached to the ole gal as she's my first bike Quote Link to comment Share on other sites More sharing options...
Stu Posted January 13, 2016 Share Posted January 13, 2016 Hoggs give some of this a go http://www.opieoils.co.uk/pv-1029-silko ... AtaP8P8HAQ cold weather problems are more than likely carb icing the zx6 is a twat for it for £13 its worth a try although I wouldn't have thought it was cold enough in landan just yet Quote Link to comment Share on other sites More sharing options...

One of the exhaust studs is snapped on the replacement engine, will either get it out or spot weld the exhaust onto it! Don't expect the bike to last too much longer with track use and mrs going to use once she passes her test. Quote Link to comment Share on other sites More sharing options...
Hoggs Posted January 13, 2016 Author Share Posted January 13, 2016 Will order some tomorrow cheers Stu. Weirdly it's a lot colder where I work so it only backfires in the evening. Scaring my colleagues haha Quote Link to comment Share on other sites More sharing options...
Stu Posted January 13, 2016 Share Posted January 13, 2016 some coils also like to play up in the cold until the bike has warmed up too! Quote Link to comment Share on other sites More sharing options...
