Maybe coming from filter box?Have you checked your drain line connection down to the black bottle by the center stand?

My guess is that its dirty around the wires and coils and up underneath and when you ride it falls off, Heat shield could be dirty...Looks like dirt and oily stuff to me, looks like the kinda stuff that sticks to the bottom of a coil...Dust and dirt...That's my guess...take a white cloth and run it up under there,, my bet is it's gonna come out filthy... :lol:

what ever it is, it looks like its coming down from the middle of the motor and running down the side. is that the.........starter in the bottom of the photo? because that looks like the bottom of the motor. if he could just take another pic of it so it can be seen from looking straight at the motor.

It's the top left side of the engine looking down towards the starter, see the hose tube and the other hoses,, Ding dong could be correct that it's a bad seal at the inspection cap ...

Indeed,,, the inspection cover cap that sits on the top of the engine.. :D someone said the air filter,, well when I got my bike, everything got a good cleaning, every single wire was cleaned up at the mounting areas, 30 years old, that's a long time...the guy before me didn't bother with any of this..It was a bloody mess...

oh yuck, that must have been a mess. I've had my bike for almost 2 years and im STILL cleaning it, under the seat wires, behind the fairing wires, under the false tank, swing arm, bottom of the motor, just about everywhere I can get to I've been cleaning it. its like a never ending process.

Did you wipe the top part of the motor just before taking the photo or is that the way it looks? Is it just me or does it look like it could be something smoking up from under the starter and it's soot residue?

It's hardly chafed through the insulation on the red wire going to the starter?

is it possible that red wire covering just behind the starter is broken and rubbing against the starter bolt creating that black line up the side of the motor? because to me, it seems like its actually touching that bolt. doubtful but possible?

Yep, and if it was doing it while on the side stand that would explain why the black mark is lighter on the top of the motor..

that sounds feasible......HEY squirrel, you need to remove that + wire to see if its bare behind that spot where it seems to be resting against the starter bolt and either replace it or wrap some electrical tape around it and move it slightly away so it doesn't burn out your starter and other relays or worse case, start a fire under your leg.

Apologies for the picture . I've not had time to check all the excellent suggestions but I'm pretty sure the stuff is coming from the top somewhere .I'll be able to get a better idea at the weekend when I can take it apart .meanwhile another picture ( hopefully the right way up )

from what I can see, it looks like its coming down from the middle center of the motor. its possible it is the timing inspection cap. plus looking at it closer, it looks like you could use a new fuel hose going from the petcock. its dry rotted and starting to get some crack lines in it as is the hose going into what ever that part is right behind or under that rear engine mounting bolt.

is it possible that the fuel hose is leaking and what your seeing is residue of fuel and rubber running down the side of the engine? ya know, to eliminate all possibilities, get yourself some engine degreaser and clean that engine off, then if its dripping down onto the motor as much as you say it is you'll find exactly where that is coming from.

it should be located on the top of the engine block just behind and inbetween the back 2 carburetors. let me check my repair manual and i'll give you more info on it. give me a few minutes.

Postby roadwanderer2 » Sun Feb 22, 2015 4:53 pm

ok........you have your fuel hose, (the one that is dry cracked), and the other hose that goes to that other connection, which I am assuming is a breather hose, the cap is located, or should be located just behind that one hose on the left top of the engine block just behind the rear carburetors. you'll have to remove the fuel line and that other hose, and maybe the false tank shelter to get to it. my CD manual wont let me copy and paste the photo of it, so unless wingadmin or someone else can show you a photo of it this is the best I can do for you. sorry.

I have an idea that you might want to try. go onto your country's eBay site, type into the searchbox.........."1982 GL1100c engine" and it should bring up the page with the bike motor. take a look at it and look for a slotted flathead cap on the top of the block, that SHOULD be your timing cover cap.

here's one I found on my embay site, type this number into the searchbox..........251761673262 put your mouse over the photo and it should enlarge it and you'll see the slotted cap on the top of the engine block. that's your timing cover cap.

If you stare at the first picture, you can see the starter wire on the inside is black , and I bet crunchy feeling where it has been grounding out when power applied to the starter. That's is what I think it looks like to me.

not only is it touching the starter, but its also up against the engine casing at the back of the motor and on the end of the starter, but what would make the black color on the top of the part where the breather tube goes into and towards the middle of the engine block. that's what I cant figure out. wouldn't it stand to reason that the starter would have shorted out and the starter not work and the rest of the sheathing on the starter wire would be totally burned off if its still connected to the + side of the battery?

Not sure if this helps but the starter motor is a ricks 4 brush where the connection is at the front closer to the exhaust headers .both the starter motor and lead are brand new only a couple of months ago.
