    Cam Chain Tensioner. Beware messing with it without prior knowledge of how it works can lead to bent valves!!!!

    Do a search as there is a number of threads and hours of reading available and they did it better than I can.

      look for cam chain tensioner....

      There are three places they can leak:
      1. At the base, where the thing attaches to the motor, there is a gasket there but it can leak. Fix is to replace the gasket\use RTV
      2. On the left side as your looking at it, where the bolt and jam nut enter the tensioner housing, there is an o-ring in there that can get torn/flattened/worn out. Fix is to replace the o-ring
      3. On the very "front" end there is a rubber type plug in the end that very often leaks. Fix is to remove, clean and then replace using generous amounts of RTV.

      Both 1 and 3 require the removal of the tensioner housing from the engine, make sure you read up - you want to turn the engine by hand clockwise to the "C" mark on the timing plate before you remove it, and then re-set the tensioner, install, loosen the set bolt, tighten the bolt and jam nut, and then turn the engine over by hand just to be sure the chain didn't slip. Make sure to pay attention to the bold, bent valves can occur if the timing chain slips!

      Also a lot of folks have switched out the manual adjuster for an automatic type from the v-max or venture V-4's. I believe they are less likely to leak and are automatic, but I haven't done that myself.

        You are looking at the cam chain tensioner. They leak.
        Use the search button on the bar above and do a search for "leaking cam chain tensioner" you will find plenty of information the problem.

        Just be very careful about just pulling the tensioner to seal it up. There is a set procedure to keep from bending a bunch of valves. That is covered in there as well.

        That procedure is coming up real soon on my bike as well.

        I need to type faster. again.

          If you do have to remove the tensioner, make sure the bike is on the centerstand. Removing it on the side stand may allow the chain to fall off the crank sprocket to the left side of the bike. EZ fix for a leak out of the front is to clean all the oil off and load a gob of RTV in the end. No need to remove anything. If the leak persists, then the o ring and/or base gasket is at fault.

            theres a little drain spout
            That's the best description I've heard yet for the stock tensioner .
            I think I have a loose screw behind the handlebars.

                THERE ARE NO EXPERTS WORKING AT MOTORCYCLE SHOPS!!!
                These bikes are older than most of the "Experts" that work as "Technicians" now. A quick fix for the leak is use brakeclean to degrease the area, and use a GOOD RTV to seal up the end that should have a plug in it. ten minutes and about $10 for everything you need. Do a search on motorcycle shop repairs BEFORE you take your bike in.

                  After reading the shop horror stories many have posted, if I were not "handy" I would seriously consider throwing a little money and a lunch at another forum member that lives near by before taking the bike to any shop.

                  If you update your member info with your location and post that your looking for help I'll bet you'll find another - more experienced - member nearby that would be willing to help you out. It will probably be much cheaper, you'll make a new friend, your bike won't come back all screwed up, and you might even learn something if you want to.

                  If you consider yourself "handy" then you really can do it yourself, it sound like a big deal but as long as you read some of the older threads on what to do, take your time, follow the directions, and turn it over by hand before cranking with the starter you'll be fine. There is a lot of knowledge and support on this forum!

                    Definitely!! DO NOT take your bike to a "mechanic"!! They won't know what they're looking at, and will likely cause more problems than were there to begin with, then charge you an arm and a leg to do so.

                    The advice and guidance here an literally get your through ANYTHING your bike might need to have done to it. Just take your time, read, and ask questions if you get stuck. You will save a TON of money, and feel a huge sense of satisfaction when you're done.

                      I dread the day I have to dig into the head and cam area (and I am sure I will end up in there this winter if not sooner), but I know the advice from this board will help greatly!

                        I mentioned the fact that I was working on a 79XS1100 to a younger guy that was working in a bike shop and I had to look over my shoulder real quick to see what he was looking at. Then it occured to me that the thousand mile stare was because he didn't have any idea what motorcycle I was talking about.

                        If I really had to rely on one I would stay away from the bike shops unless the guy has a good bit of grey in his hair. Even then......

                              paint is a good thing...

                              but please keep in mind that you need to get it running good, First.

                              if you rebuild:
                              carbs, fuse box, Forks, brake master cylinder and caliphers,
                              pick-up coils, coils, TCI resolder, and all is 100% running condition.

                              then is when you want to tear down for paint.

                              because then if (when) you have an issue with the bike it will be a minor one.

                              not 12 things all ganging up on you frustrating the hell out of you.

                              so please, use caution and look through tech tips and see what issues
                              your model is known for having.

                              there are lots and lots of hours of reading here all containing alot of very helpful information.

                              so please use the search option to see what's allready been covered.
