Strange happenings with my bike

[Tigadee]

Thanks, I can pop by.

This morning, gave the girl a wash and shine. Started her up and no issues, first time it turned over and purred like a pussy... cat, that is.

Subsequent re-starts again with no problems. Maybe the old gal doeesn't like cold?

What, did you expect it to fix itself?
Chances are you're going to have to take to it with a voltmeter and wiring diagrams, hoping for the best is more likely to leave you stranded on the roadside than the problem disappearing.

I know, I know...

Sometimes a wire that has been soldered into place like switches and stuff can be real hard to find, a magnifying glass helps here. I have had problems in the past with stuff like that, could not see anything by eye, but with the glass it stood out straight away. Just my 2p,s worth.

Aye, what did you find? A wire 'unstuck'?

So I had a look at the mighty Yammy. Both battery terminals had some corrosion so we cleaned that up along with the main earth to the motor. Found a terminal on the positive side that went no where so that got binned. She started fine and turned over faster than before. Checked static volts and running and it was showing 13v static and just under 14v at 4k rpm. Gave the kill switch a quick look and a bit of a clean.

I think we are dealing with 2 faults at once. The bike stutters at motorway speed then comes back. The whole time we were working on it the tank was whistling. So to me it sounded like a clogged tank breather. The tank breathes through the cap so we pulled it apart. Inside is a little diaphragm that I guess is to stop overflows of fuel in the sun. It seemed brittle so as a test we pulled it out. The next motorway trip will tell.

Time will tell if I got it right thus far.

Well, I made it home, didn't I?

Yeah, that sound was like a owl, "Whoooo... whoooo". I didn't have a name for the Yammy before, but not I shall call it "Archimedes" [Merlin's owl in Sword in the Stone]...

Thanks so much, mate! No sounds from the bike now and a slight hesitation when I twist the wrist is gone now too.

Beer on me this SASS, aye Spokes?

Beer, you tight bastard, get the man a whiskey or 4.

Wait till payday then - I'll be tighter than my abs and buns of blubber!

And thanks for showing me what and where and how, Spokes... Teach a man to fish and all that!

By the way, dont super fill the tank and leave the bike in the sun. No stutters on the way home?

[Tigadee]

By the way, dont super fill the tank and leave the bike in the sun.

I have to admit I am guilty of super filling the tank because it's such a small one...

I do cover it when I park it outside at work. Is that good or is a cover useless where sun heating up petrol in the tank is concerned?

No stutters on the way home?

None whatsoever. A good sign but the next few days will be the best indicator if the issue has been resolved [esp. if in addition there is no more non-starting problem too].

Oh dear, it lost power 3 times on the motorway this morning, again just for half a second each time.

Then when stopped at a red light, it died. I had to put it into neutral and then it started again. Did it again a second time at a red light...

fault list, wiring diagram, no more riding

It's electrical man. Stop riding it and fix it, before it stops you from riding when you're away from the shed.

[Tigadee]

Yessirs... Right, park it up I will then.

Now where's that wiring diagram i have somewhere...?

A wiring diagram will save some time.

Tell me, do the ignition lights go out when it's fucking around? Or the head light for that matter?

If not, I would start by looking at the kill switch circuit. If they do blink, look at the ignition switch circuit.
