Wet Weather Rough Running: Coils and Leads - pistolwhip - 18-03-2008
there's an idea.
Its been hot the past two days. (everyday dry day lost is terrible) Think if it was damp it would already be dried by now. But good. will try wd40 drench. Maybe its one of those electrical demons thatâs been haunting meâ¦
donât think this is relevant, but i remember riding away from the mechanic shop with new bt20's and immediately throttle cable was wrung till little dial in gauge reading rpm fiddled in the red. [img]style_emoticons/<#EMO_DIR#>/rolleyes.gif[/img] cos the bt20's are that good.
so donât know if it was water or carbs getting stunned? dont see anyone complaining about carbs.
for reference, wrapped the leads from the inside of the bung on the engine head right until the connector on the coils. Also wrapped all the coil connections.
scraped corrosion away from all above said contact points before taping.
still nowt. frightening when it dies during lanesplitting.
will douse underseat and plug the gaping hole and see what happens.
cheers.

strip, inspect, clean or replace the starter relay, which is located under the seat.

ok captain.
very possible relay or fuses. mounting and position dont look very well thought out.
i'll see how this one goes.
cheers all.

that would be very good. juz took a good look and in comparison to whats in the manual, theres seems to be plenty of macgyver mods there.
this is getting amusing, as in the "erm..." kind of amusing, not "hehe".
thanks in advance.
cheers.

yes it was actually working !!! that relay was from Emmetts original MKIIa, i have his wiring loom in me attic and that block connector was really corroded, even the plastic had gone brittle and it looked loike a potential foire hazard to me !!!

Wet Weather Rough Running: Coils and Leads - pistolwhip - 24-03-2008
problem solved! [img]style_emoticons/<#EMO_DIR#>/yahoo.gif[/img]
unbelievable.
did what wickle suggested. [img]style_emoticons/<#EMO_DIR#>/good.gif[/img]
stripped the starter relay to pieces, took the battery +ve (the red thingy to the relay) and -ve (the black thingy to the frame) leads and cleaned, sandpapered, installed everything. taped up, installed a cover for the gaping hole (mod from an empty tub of walls ice cream) and now she runs like she used to.
trying to find this on my own would have taken ages.
thanks a bunch all. [img]style_emoticons/<#EMO_DIR#>/drinks.gif[/img]
p.s; maybe i should email a photo of it to yamaha. they have a team of engineers, a gazillion bucks for research... and here's an empty tub of ice cream and a bit of sandpaper. they can file it under 'ridiculously simple ways to solve stupid engineering problems'.

tried to post this elsewhere, but apparently this is a first.
uh-oh # 2
radiator cant hold its water. Small squirt between the fin run and the solid rectangle top. Corrosion? (4TX090A model) spark plug spanner swung recklessly?
small little thing, pity to replace the whole unit.
Any recommendations?
patch? hi temp metal adhering cement/epoxy?
welding?
leaks only when radiator reservoir is full of course.
No problem with overheating yet. Even with nearly empty coolant, mercury stops off dead centre.
hahâ¦suddenly remember.. whats that movie with the jeep with the leaking radiator and the smart alec with the eggs?
funny that. 'haha' funny.
stop me when this gets old.
anyway, plenty thanks all round.
cheers.

<!--QuoteEnd--><!--QuoteEEnd-->I didn't know that came apart!!! [img]style_emoticons/<#EMO_DIR#>/unsure.gif[/img]
Cleaned mine out properly this afternoon; it was nearly as bad inside as your pic, the connector was clean.
Did you use that drill to clean yours up? I found the copper was so fragile/bendy I used an old emery board I found in the cupboard (no it wasn't mine...), and it came up a treat.
@ pistolwhip.... Off to buy a tub of ice-cream now. Does it have to be Walls or will Co-op do? Chocolate or raspberry ripple??? [img]style_emoticons/<#EMO_DIR#>/rolleyes.gif[/img]
Wet Weather Rough Running: Coils and Leads - nick16934 - 01-04-2008
This is doing my head in now....
New coils, new taped-and-sealed HT leads (not touching any metal), new plugs and caps and STILL the thing cut out this morning. Still sparking from the RH coil
Only thing I haven't done yet is change the plugs that connect to the coils from the wiring loom. They do look a bit blue (like the starter relay in Wicky's pics above). Only other thing I can think of that causes this. I have done everything else...

Side stand switch!!!!!!
Wet Weather Rough Running: Coils and Leads - Guest - 01-04-2008
have you tried a high temperature silicon (or similar) sealant around where the plug caps go into the engine, i think water may be able to seep past the rubber seal on the plug caps into the holes, it has got to be worth a try.
Wet Weather Rough Running: Coils and Leads - nick16934 - 01-04-2008
PB I could give it a try I suppose. I bought a tin of damp-seal earlier which I know is only supposed to be a temporary fix. At the weekend I am going to change the connectors on the end of the wires that attach to the coils and spray the lot with damp-seal.
TAM, how could the sidestand switch affect it? I have to admit now that I know NOTHING about electrics; hell, I struggle with a 3-pin-plug!!, I am just trying to follow a simple process of elimination. And am open to all suggestions.
When I peered up under the headstock this morning when I got to work, I could see brown marks around the bottom of one of the coil pins and it definitely was sparking either from the bottom of one of that pin or where the coil fixes to the frame - bad earth maybe?
I have read <b>all</b> of the threads in this section of the forum, and followed <b>all</b> the advice. Surely I should have sorted this by now.
Wet Weather Rough Running: Coils and Leads - geordieguy - 01-04-2008
Side stand switch cuts the engine out when you put the side stand down.
It could be full of crap, loose connection or faulty.
Get on your hands and knees when she is running, give the side stand a wiggle when its up, try and make it cut out.
You might have to take it off and see if its cerroded.
Good call TDMTAM...... [img]style_emoticons/<#EMO_DIR#>/good.gif[/img]
I would not have thought of that one.
Good Luck
Ivan

either way i'd trace the sidestand switch wiring and clean any inline connectors. I used a Dremel to clean the kontacts of my starter relay.
Wet Weather Rough Running: Coils and Leads - nick16934 - 17-04-2008
Going to do this at the weekend when I put the bike on my paddock stand to clean the swingarm [img]style_emoticons/<#EMO_DIR#>/yahoo.gif[/img] shouldn't be too hard, and I have a wiring diagram that I can follow if I get lost.
I also managed to 'borrow' some hi temp silicon from under the counter at work so I did as Pantboy suggested.
Just waiting for it to rain now so I can test it all out. Saturday afternoon looks promising...
Wet Weather Rough Running: Coils and Leads - wicklamulla - 17-04-2008
ps. i would also squirt summit ACF50 down the ignition switch to help clear up any corrosion that may be on the contacts.
