Think I fount the leak....maybe..

[Condor]

Some of you may already know, but 7 of 9 barfed all her coolant after the first days ride at VW-Shasta. I parked her, turned her off, and got off. There laying under the middle gear cover was a puddle of coolant. So I let her sit overnight and the next morning the puddle ran from under the stator cover all the way back to under the final. So put her back on the trailer, hung around till Saturday, and went home early.

 

I was praying that it was the rubber plug under the fin. No such luck. I haven't raised the tank and filled the radiator yet, but in poking around I ran into this. The first pic is of the'99, and the second is of 7. It's a hose, and the problem is I don't have a clue to where it comes to, goes to, and what it's called. Can't find it in the parts manual.. One thing for sure is the hose on the '99 clears the oil fitting by a country mile, and the hose on 7 looks like it's close enough to rub and chafe. With big hands I haven't gotten in there to feel around yet, but it's a possible???

I think it's a vacuum hose. If so, there shouldn't be any coolant in there.

Jack, just reminder her that "resistance is futile"!!

It's a pretty big vacuum hole Carl. If you look closely at the pic from 7, I think?? I can see coolant residue on it. That's what made me think it might be a chafed hose. Another thing is the residue is all on the stator cover side. The other side of the twinkie is dry and dusty. That's why I was hoping it was the rubber plug... I'm going to replace the coolant tomorrow morning and see if I can spot something once it heats up. I also have a problem with the clutch. The reserve is full, and it will start in neutral, but when I try to put it into first the trany clunks and the engine stalls. The bike will not free wheel when it is in 1st. It will start in 2nd, but still wants to lurch forward a bit. The clutch seems to be grabby, but works well enough to ride it into the back yard. My thoughts are when the engine overheated it cooked the slave seal and I'm not getting enough movement to release the pressure plate all the way. We'll get her fixed. One thing I know about is clutches.... But first things first... :-)

Yep... Go with the flow...

I was looking at the other hose.

Sorry...should have been more descriptive... It's the larger hose behind the smaller one that looks like it came off a 1stGen.... In the pic from the '07 it looks like it might be rubbing on the top of the oil journal... Hope it has a hole it..

OK, well I tried to cut and paste the Cooling System diagram from the RSV service manual here and it didn't like it (or at least my computer didn't). Anyway there are a number of joints in the cooling system that could be the culprit. If you want just the hose diagram or need the RSV manual let me know.

All the diagrams are available in the tech section which is a pita to get to, but I also have them saved to my computer. The parts manual actually has the diagram. The Chilton has a great water pump pic. I think it's better than the OEM manual.
