Starting Issue - AGAIN

[His Dudeness]

Unfazed to the rescue again Although I'm still expecting tomorrow's thread. It took 0.8 seconds to start instead of the usual 0.5 seconds :lol

I love it when it's all running properly.  :lol

I agree. I don't know how people can ride around ignoring problems when a small bit of effort has it running sweet

Couldn't ignore that backfire on Thursday, i think the receptionist at work nearly shat herself, 'cos my exhaust was aimed at the reception area glass window.  :rollin

[darrsi]

Goddam it, it happened again tonight.


Took a bit longer to start as well, and this time there was an even bigger BANG, then it started and ran absolutely fine all the way home.


Any more ideas people? I need to get this sorted before the really cold weather kicks in.

Your issues is still with the plug caps and wires. Look closely at the coil wires and you will most likely find corrosion. If not there it will be in the caps.
Back to the old cut 10mm off the ends and if OEM caps take them apart, they suffer from corrosion on the spring and washer within or break down of the carbon resistor.
NGK ones are less prone to issues as they have wire wound resistors, but salt can eventually cause problems

[darrsi]

I've got the NGK caps on my bike, and they're a really snug fit and sealed rather well, so don't know why there should be corrosion, but i'll have a look on Saturday, when the weather gets a bit more miserable.
Cheers unfazed.

I'd try putting some standard plugs back in it.  It may not be the problem, but it's a cheap thing to try.

You don't normally use the choke, but have you tried giving it 1/4 - 1/2 choke from cold?

Previous plugs were Iridium.

Not since last winter, but i'll give it a go after work later.

Reminds me of an old guy I used to work with in the late 90's. He had a diesel Mondeo as his company barge and always complained it was a bitch to start. One day I was walking through the car park as he jumped in his car and turned the key. cranking and cranking before it finally fired up with clouds of smoke everywhere.

Next day I asked him if he had waited for the glow plug light to go out before cranking it? "the what?" was his response.

He never had trouble starting it after that afternoon.

[darrsi]

Bike just doesn't normally need the choke until the REALLY cold weather kicks in., and even then that's more for warming the bike up rather than actually starting it.

[darrsi]

Wasn't instant but started reasonably well with a bit of choke from the off.
Can't help feeling it's more of a cheat than a fix though, so i"ll chop the leads as well anyway and refit the caps.

[darrsi]

I couldn't see any wires at all on HT lead number 1, presumably they get pushed into the walls of the cable over time?
Anyway, i chopped the ends off and refitted the caps so hopefully it'll behave itself now, plus it started instantly as well. 

[darrsi]

Can't believe what a difference it made to the running (and starting) of the bike just by trimming the HT leads!
I honestly thought the bike was already running sweet enough, apart from the starting issue, but after riding the bike yesterday and today it now feels perfect, not only is it starting straight away on the button again, but the engine feels noticeably better in traffic in lower gears.

Job's a good'un.  :thumbup

[Dudeofrude]

Well done. Even better when it's a free fix too ?

[robbo]

Everyone loves a free fix.Well done darrsi.Just got to plan what to buy with the money you've saved :lol

[darrsi]

I've been trying to avoid asking again but i'm genuinely stumped now.
Bike seemed to be starting okay over the last few weeks, used a bit of choke in the cold and it was pinging to life so i could let it warm up for a while.


NOW IT'S NOT  :'(


For at least a week or more now the bike just doesn't wanna know about starting until a good minute after trying.
With choke, without choke, no throttle, half throttle, full throttle.....
The new battery has been great, so there's not been any issue of power, when cranking over the battery has not tried to die down or anything and has produced a solid source of volts.


Then, after going through all of this rigmarole, morning and evening, the bike will either just ping to life, or as happening tonight again it will make my exhaust look like a rocket launcher, make an almighty bang when backfiring, then ping to life.
It has been suggested to me to try starting with the stand up in the morning, as although i bypassed the faulty side stand switch it does resemble the issues before i figured out what it was.


Other than that, i'm at a bit of a loose end?


As soon as the bike is started it literally runs perfect in every way, with no missing, hesitation, spluttering, etc.


Any ideas welcomed please?

Sounds like water in the fuel again
