meant to say mate, i did think the intake block may possibly be masking another more important fault like the coils and thats why now, i`m tending to lean towards the problem being down to an ignition fault...........carbs as i have mentioned umpteen times before are fine. no damaged parts or mal-adjustments. they have now been ruled out full stop. ( time to be a man about it

)

I wouldn't place too much reliance on the measurement of dc resistance of the coils.. it'll tell you if there's an open circuit, but not much beyond that.
In this case I'd guess the slightly high reading is either contact resistance or that of the leads of the meter.
Coils normally fail in one of two ways, either one winding goes open circuit or one develops a short between adjacent turns... the latter isn't detectable with an ordinary meter, but it'll kill the spark. What's more, the short can be intermittent, often dependent on temperature. Swapping some known good coils in is the only easy way to check unless you've access to test equipment that'll measure mutual inductance.

thanks fazerider. that calls for another magners

Sounds good to me, cheers *clink*

I've been following out of sheer curiosity now and have mentioned it to several friends who are also bewildered. I unfortunately am not technical enough to provide any assistance that this point

morning all....i think your on to something with the different readings on the coils although as fazerrider states dont rely on the readings what you can rely on is the differencs in the readings...go compere (sing out loud if you want)
i had my multimeter stolen at work a few months ago i`ll see if i can replace it today and do the same test and compare with your figures , iam also still watching several auctions on ebay for carbs and coils with most ending this weekend,will make a bid if the price is right
iam starting to think the same as you theres only so much that can go wrong with carbs and there pretty easy to understand,when i eventually get my carbs back i dont think the problem will be solved but i can then elimante the carbs as the source of the problem.
thinking back to autumn last year i did notice that the fazer was struggling to start, normanly on the button hardly turning over,wonder if this was early stages of coil failer

....or just the origanal battery getting tired $:\$

Also check the generator voltage

afternoon ade the blade....ive been shopping this morning and bought myself an EX-ARMY MISSILE LAUNCHER

..............just made that up,what i did buy was a new multi meter,ive now done the same checks as you on the coils
primary coils secondary coils

coil 2 +3 2.7 ohms 14.1

coil 1 + 4 2.7 ohms 14.5

a little high on the primary readings (should be 1.87 - 2.53 )and just about bang on with the secondary ( should be 12 -18 k-ohms )

..... also checked the caps old origanal ones range from 10.0 10.7 10.8 12.3.....should be 10k-ohms so no real dramas there , last one may be questionable....the new ngk caps are printed on the sides 5 ohms and readings are 4.7 5.1 5.2 5.5 again no problems
looking at your readings on your neighbours mulitmeter it is suggesting that the coils are out of spec,which is one hell of a coincidence unless of cause something else has caused the coils to fail....i`ll look at the wiring diagram and see what i can learn
anyone know why the ngk readings are 50% lower by design ? and would this affect performance ?

Red, the value of the plug cap resistance isn't critical. The purpose of the resistor is to damp out any high frequency oscillation that could cause interference to radios. 5k ohms will do the job just as well as 10k and it'll have no effect on the spark, but if one of a set is a fair way out from the others it might indicate the resistor is breaking down.

thanks for that fazerider.....ade the blade,have you made any progress today

thanks for that fazerider.....ade the blade,have you made any progress today

managed to draw a cracking figure of eight with me todger........does that count?

. no tinkering today. had a bit of a coolant leak to sort on me own bike......that takes priority, bitch. may take a peek in the morn. interesting results ya got on that meter then? keep dancing.........er sorry wrong show.........keep searching..............tess daly, mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

red98 · « **Reply #60 on:** 31 March 2012, 10:05:18 pm »

a figure of eight

.....is that as good as a smooth running fazer

hi mate...you made any progress with the fazer........

ade the blade · « **Reply #63 on:** 05 April 2012, 11:08:40 pm »

been flat out working on other peoples bikes ( you can tell its easter ). will try and get an hour or twos tinkering in over the next few days. hectic as hell but it pays well.

how about you and ya yami pal?

morning ade....got the needle jet and now have the carbs back ready to fit.tommrow all being well..will update sat

Is the TPS connected? Maybe the fuel filter "inside" the tank is gummed up not allowing enough fuel through?. Could be a bad earth? these are all i can suggest good luck mate.
tps checked and connected......tank gauze filter fine.............been through leccy system with a lot of patience, all fine from what i see.
thanks for taking time to add input Ade

morning ade....did you check the tps according to haynes or is there another way ?

ade the blade · « **Reply #66 on:** 08 April 2012, 09:45:17 pm »

evening my lovely

. checked it against yami`s service manual. same spec in haynes if i remember. pity carbs didnt sort it 100% for ya but as you say its almost there. aint even looked at this one lately. was hoping for some time this weekend but no, everyone wants work doing pronto. aint got anything specific in mind anyway just yet to try out

. comfort eating for now with easter eggs

. keep at it !!!

mates has similar prob an he`s just joined

has anyone checked fuel rate??????
