marcaztls Posted March 19, 2014 Report Share Posted March 19, 2014 If nothing changes when one is removed, then it proves it's actually only idling on one cylinder, not two like you think. It's hard to tell this by exhaust pipe heat as the bike won't idle from cold startup, so removing one cap at a time can give you an idea but try not to run the bike any longer than necessary as it's not healthy to drag a dead pot along. If it's running on one all the time, then you need to do some wiring tests to the offending cylinder's coil, if that checks out, replace cap, lead, coil in that order. If it is indeed idling on two, but cuts out under load, I'd still suspect cap, lead and coil in that order as all can break down under load. Then it's a bit more complex but we'll get to that if needed. This is all assuming the plugs are brand new, very recently. Also don't assume that a new plug is guarranteed to be fine. I have had new ones out of the box which cause problems. Granted I change a hell of a lot of plugs. Oh, it's Mark by the way Stupid username, sorry.

markw Posted March 19, 2014 Author Report Share Posted March 19, 2014 thanks Mark , great name and great advice, i'll have a look this weekend and report back Link to comment Share on other sites More sharing options...
markw Posted March 23, 2014 Author Report Share Posted March 23, 2014 so finally managed to get some time to take bike apart, started it up, removed cap and bike kept running..... when i looked at the plug it was covered in petrol which would indicate its not firing..? the connectors to the coils are a little dirty but nothing to worry about with the tank off i might as well get a new fuel filter the coil on the right hand looks like its been off as its got tippex on it..? so i might as well get new leads and caps and see if that gets me back to where i need to be i'll get my mate at his garage to check the coils thanks Link to comment Share on other sites More sharing options...
BudgetBoy Posted March 23, 2014 Report Share Posted March 23, 2014 Tippex = 2nd hand parts. Used for marking what they are ect..so i think you may have found your problem (wet plug,coil no sparky). Who knows how long that 2nd hand part was on the original bike.. Get new and you will be sorted. Link to comment Share on other sites More sharing options...
markw Posted March 23, 2014 Author Report Share Posted March 23, 2014 sorry budget, the coil with the tippex is the front one, and the one i think is ok, so looking like the other ' older ' one..? with the wet plug cheers Link to comment Share on other sites More sharing options...
BudgetBoy Posted March 23, 2014 Report Share Posted March 23, 2014 sorry budget, the coil with the tippex is the front one, and the one i think is ok, so looking like the other ' older ' one..? with the wet plug cheers oh, so thats been replaced then.. Im sure its the coil breaking down.. Have you tried swapping the coils over? if the problem moves (wet plug) you have found the issue. Does sound like a coil now though.

markw Posted March 25, 2014 Author Report Share Posted March 25, 2014 so i took the coils to the shop to make sure they were a match, helpful mechanic tests coils and leads and says there is nothing wrong with them................... he says it may be an injector or shims tightening up as bike hasnt been used for a while i am losing patience Link to comment Share on other sites More sharing options...
markw Posted March 26, 2014 Author Report Share Posted March 26, 2014 i have found the dealer mode and its saying fault 21 & 23.. but the air box isnt on so i presume that would bring some faults up.. any help appreciated Link to comment Share on other sites More sharing options...
BudgetBoy Posted March 26, 2014 Report Share Posted March 26, 2014 i have found the dealer mode and its saying fault 21 & 23.. but the air box isnt on so i presume that would bring some faults up.. any help appreciated 21 is intake air temp sensor. (low/high or just malfunction) 23 is tip over sensor or circuit malfunction Link to comment Share on other sites More sharing options...
markw Posted March 26, 2014 Author Report Share Posted March 26, 2014 thanks Budget, will this affect the running of the bike... ie my problem....? Link to comment Share on other sites More sharing options...
BudgetBoy Posted March 26, 2014 Report Share Posted March 26, 2014 Well id want to get them sorted.Thats why the dealer more is there mate. Sort C23 first. ""The sensor voltage is less than the following for more than 8 sec. after ignition switch turns ON. (0.25 V < or = sensor voltage < 4.85 V) Without the above value, c23 is indicated."" Or "TO sensor, wiring/coupler connection." Do you have a manual.. like say haynes or clymer? Link to comment Share on other sites More sharing options...
markw Posted March 26, 2014 Author Report Share Posted March 26, 2014 yeah got haynes manual, Link to comment Share on other sites More sharing options...
BudgetBoy Posted March 26, 2014 Report Share Posted March 26, 2014 Ok, id be using that if i were you to check the the wiring diagram. Check all the relevant the connectors.. Im gathering you dont have a multimeter.. If you take an hour or two to read the manual ,, iirc there is a problem part in haynes at the back? use that as a guide.. This will also give you a better understanding of your bike.. Link to comment Share on other sites More sharing options...
markw Posted March 26, 2014 Author Report Share Posted March 26, 2014 thanks budget, i do have a multimeter but to be honest as you may well have gathered , electrics arent my strong point thanks for all your advice, it is appreciated Mark Link to comment Share on other sites More sharing options...
BudgetBoy Posted March 26, 2014 Report Share Posted March 26, 2014 so i took the coils to the shop to make sure they were a match, helpful mechanic tests coils and leads and says there is nothing wrong with them................... he says it may be an injector or shims tightening up as bike hasnt been used for a while i am losing patience BTW,, did or have you actually fitted the other coils you were going to get? testing them off the bike wont always work.(not under load,and not hot) So for peace of mind id try the NEW coil as well. You can always sell it if its ok. But to be honest you need to start with what Mark said 1st.. Coils,leads,new plugs, fuel filter. And sort the fault codes then see where you are at... Anything else and you are guessing. (IMO) Link to comment Share on other sites More sharing options...
markw Posted March 26, 2014 Author Report Share Posted March 26, 2014 ive been guessing all the way through .....!!! no didnt fit them, good point though, i'll get them tomorrow Link to comment Share on other sites More sharing options...
lorenzo Posted March 26, 2014 Report Share Posted March 26, 2014 Fit them the other way round and see if the faulty cylinder follows the coil. Link to comment Share on other sites More sharing options...
markw Posted March 29, 2014 Author Report Share Posted March 29, 2014 so i think ive sorted it, with the help of all you helpful people...!! fault codes were indicating sensors not plugged in, so they are ok i cleaned all the connectors, put some redex in and fresh fuel in and it now seems ok i checked the plugs again and both are ok, no smell of petrol now, maybe in was just a dodgy connector..? or just needed running a bit more after being sat still for ages im gonna give it a proper run tomorrow thanks again guys..!!! ( now onto the handling ) Link to comment Share on other sites More sharing options...
markw Posted March 30, 2014 Author Report Share Posted March 30, 2014 so went out today and stuttering has started again, but bike cut out as well, the kind man at the rac said the starter relay has been taped up and bodged , so need to sort that but will that affect the running of the bike...? help appreciated again cheers Link to comment Share on other sites More sharing options...
lorenzo Posted March 30, 2014 Report Share Posted March 30, 2014 No, the starter relay won't make any difference once it's running, unless it's something especially odd and unpredictable. So, have you swapped the coils round since you've had them off, and does the cylinder that cuts out follow the coil? Have you sorted fault 23, this'd cause the problem if it's making an intermittent connection perhaps. Link to comment Share on other sites More sharing options...
markw Posted March 30, 2014 Author Report Share Posted March 30, 2014 ok Lorenzo, ive swapped the coils round and i took the plugs out and both were ok, no unburnt fuel, i cleaned all the connectors and took it out and it went beautifully, or like it should..!! then it conked out , rac man came and then i got it home.....so i just presumed it was linked to that Link to comment Share on other sites More sharing options...
lorenzo Posted March 30, 2014 Report Share Posted March 30, 2014 OK so if your coils are swapped and the faulty cylinder hasn't followed the coil it might be worth having a look to see if error is still there. Also, is the TPS sensor easy to adjust on these? Sort the simple things out that it could be. Link to comment Share on other sites More sharing options...
markw Posted March 30, 2014 Author Report Share Posted March 30, 2014 sorry forgot to say, no fault codes coming up and the ones which came up last week have gone when all was connectors properly, TPS is worth looking at Link to comment Share on other sites More sharing options...
Rick448 Posted March 30, 2014 Report Share Posted March 30, 2014 On my blackbird a faulty starter solenoid caused it to run rough and not charge properly. I'd sort that out as well as it could well be doing the same to yours. Link to comment Share on other sites More sharing options...
markw Posted March 30, 2014 Author Report Share Posted March 30, 2014 cheers Rick, i have a feeling in my water it will fix it , as through all my searching i havent found anything much , especially if it is an intermittent fault when it was running right earlier, its a great bike to ride, 130bhp ...lush Link to comment Share on other sites More sharing options...
