    I don't think anyone has mentioned it yet, but another area that will leak is the 'o' ring seal behind the gear indicator... The indicator doesn't just screw onto the block, but actually fits in about a 1" hole in the block with an 'o' ring for a seal.

    That one I am familiar with! Had the same problem with the VStar 650. Simple fix.

    After I get the new tires on the RSV this weekend, think I'll buckle down and order the gaskets and go to work. It's time for an oil change anyway on the 89!

    Ya and if I remember rightly, the screw that holds it in place has a tendency to over tighten and so create a leaking web.

    Finally got around to ordering the gaskets, o rings, seals and the new clutch slave. Under $150 for all.
    Boats.net for the stuff.
    So the 1st gen will be getting a rebuild on it's left side. Should be good from oil leaks for the next 30 years!
    Now to go out and clean up the area real good.

    Bike is apart. Oil is drained waiting for gaskets, etc.
    Saw these stains on left side of case covers. No indication of what it is and where it is coming from. Wasn't there last year..

    But how would it get there and not stain the plastic? And no indication from heads, cylinders, cooling system, etc..

    puzzling....

    And whats worse...the Admiral couldn't figure out how to clean it off!!

    I'll attack it again in a week and a half when I get back home...is interesting though!

    Unless it's dirt and will wash off,,,,,, what I suppose that I'm looking at is the clearcoat bubbled, so a quick guess was that the handle bars were turned and the master took a leak.

    UPDATE:

    Finally got back into town and started work on the 89.

    Drained the oil, replaced the oil filter and O rings. (thanks Puc for guidance on the cover.)
    So now time to take the left side apart. The idea here is to look for a leak(s)...minor but annoying. Took all the stuff off to get to everything like plastic, etc..
    So here we go....OH...I went through all my notes of the past 4 years here on the forum, collating all the stuff relating to this job so I could have it all handy when needed. Like torque values.

    Nothing much to taking cover 2 off.

    Looked relatively clean around the clutch slave.

    But as you can see...there is oil around the wires and the area under the neutral switch.

    The clutch slave was fun to get out. But no where near as hard as I thought. It simply drops down and rotates out the hole where the wires are. You really have to move the wires up and out of the way. I also bent the wire holder near the stator wires and moved the clutch line completely out of the area after draining the clutch system. That was hard to do emotionally after all the work bleeding to get a good clutch! So once those things are moved you can drop the slave down, rotate the bleeder neck towards you and the thing fell out! Going back in was also easy....slip the slave in sideways, rotate up... then lift into position. I did have some fun trying to get the slave over the clutch shaft and then holding it down so I could get the bolts in. Put some paper towel into the hex driver then pushed that into the screw. Wanted to hold that screw on the driver as I pushed it in and got it started. Worked!

    Here are pics of the old slave. Not bad for 29 years!

    Next, took off the neutral switch/gear indicator switch from trannie case. It came out fine as well. But highly recommend you use a magnetic screw driver for the 3 screws. I managed to get one finger in to hold the screws on the driver as I backed them out. Replaced O ring, cleaned the contacts and snugged the wires on the front side to make sure they were making good contact as well....

    After cleaning contacts....

    Pretty clean area before I managed to get a rag in there. So don't think the clutch pushrod seal is leaking.

    and the neutral switch area as well...though underneath does look wet so this could have been my leak.
    BTW, I'm really glad I took this next picture as I forgot the orientation of the neutral connector with respect to the switch....I was able to look at the camera picture and see the pin is at the 8 O'Clock position....and on the front side, the raised connection is neutral. Turn the switch until it matches the pin...align holes and put the screws in!

    BTW, only mistakes I made here were I put the neutral switch in before the slave. The cables from the switch got in the way of moving the slave up into position. And then I made the mistake of reading the 2nd gen manual and it said to put some sealant on the top bolt for the slave. So off came the top bolt, RTV to the rescue then torqued the 2 bolts and that was that...I didn't confirm if the 1st gen manual said that as it's on computer and my hands were not clean enough! Can't hurt though.

    Here is the neutral switch in place....the raised wire terminal for neutral is in the 8 O'Clock position.

    Here is a close up of the wires coming off the stator. They don't look like they were leaking...but I'll leave that up to the brain trust here.....do they look normal or really wet? Don't feel wet to me....

    And that's where I stopped for the night. New clutch slave in. New O ring on neutral switch and area cleaned up.

    I could stop here and put her back together tomorrow, bleed the clutch and go for a ride to make sure everything works. I already have the gasket for the stator cover but would need to order another gasket for cover 2. I think I'll wait to see what you all say about the wires. It won't be much of a problem to drop the engine guard and take off the stator cover. I'm leaning that way now....

    Of course...that just means it's more of a chance for me to break something else!!

    BTW, it snowed today in the mountains across the valley. We got a few flakes here but it didn't stick. Too warm at 52 degrees. Another cold front came through Arizona. Picture from my driveway....

    So far working on the left side has been easier than I expected. I just hope that I can get her back together when I'm done!

    Default Re: 1St Gen - That pesky tiny oil leak

    Quick question, when taking off the side cover #2 , was there a small brass washer on the bottom bolt? Reason I ask is that there is one there. The bottom bolt can be use to drain the oil out of the transmission and from the look of the Kickstand safety switch, there appears to be some oil on that. More so then anything else I see in the pictures.
    I dont see much evidence of any major oil leaks on this side of the bike. The stator wires look clean to me and I wouldnt expect them to be your leak and everything else look reasonably clean.
    Good luck with the search as I am interested in what you find as I need to check out my 89 also..

    Unless you did a lot of nice cleaning under those stator wires, they don't look to be an issue, below them though are the position sensor wires, looks like they are ok, but can't really tell from the pictures.
    Good job all around, carry on.

    Yes, Rick...there was the small brass washer under the bottom bolt. I bought a new one and will replace it when she goes back together.

    What bothers me was the leak was small...but after trips back and forth to Phoenix at 75 mph (2.5 hours), the bottom of the bike on the left side as well as the left muffler would get oil on it. So the high speed was pushing oil out. I would clean area and go for a ride but when home...the whole area would be wet. On the ground after an hour there would be one drop about the size of a quarter. Weird cause I was expecting more on the ground. Regardless, I'm thinking the neutral switch was the leak. It may leak again as it's getting old and that plastic is probably ready to crack. I'll be looking for another switch here just in case...
    Thanks for the thoughts...

    Thanks Carl....once the garage warms up a bit I'll go back out and get back to work....32 degrees this morning. Nice!

    Once again,, I LOVE your write up here VAz = VERY well done my friend!! I think that write up should be filed in the read only tech section under "looking for leak" or something - GOOD JOB brother!!

    The pic looking toward the mountains brought of joy to my eyes,, I really really really wanna go up there and ride/camp/ride/camp/ride/camp and so on and so forth = mostly riding and camping..

    Also,, I have a hunch that that staining on your left side cover may be rodent pee.. I have seen similar before.. Might not be a bad idea to pull your air filter and check for a mouse subdivision being built... Those little critters dont always apply for a building permit so sometimes its best to check and make sure they aint doing something illegal..
    Glad all worked out with the filter housing
