    BassCliff GS850GT Top End Refresh

    Hello friends,

    I spent a little time in the "man cave" today getting ready to replace gaskets, rings, and other assorted bits in the top end of my "Jessie".

    Here's where we start. (Pretty good looking old bike, eh?)



    The airbox had actually started to slip away from the carbs. I imagine I had a slight air leak as at least three of the airbox boots were loose.



    Tank, seat, battery, and side covers removed.



    Airbox removed. You can see one of Jessie's oil catching pads there on the base gasket.



    After removing the top two bolts holding the airbox it just fell out. I guess the boots were really loose. Oops.

    Next, the carbs came out. They were still really snug. You can also see the other oil catching pad at the head gasket on this side.



    Intake boots removed.



    After loosening up the jam nut a little on the cam chain tensioner, it was removed.



    That thing is filthy. I'll be rebuilding it too.



    Just a couple of shots to show you where the main spring sticks into the knurled knob and the body of the tensioner.





    A few more pictures in the next post.

    Thank you for your indulgence,

    BassCliff

    Hi,

    I'm trying to stay organized.



    I've collected a lot of Altoids tins and I find them handy for keeping all those little bits organized. Keep the clamps, screws, etc, for each sub-assembly all together. From left to right you see the airbox clamps and bolts, the intake boot clamps and fasteners, the cam chain tensioner and bolts, and the highway bar bolts.



    And here's where I left her until next week, if not sooner. I'll start on the valve cover and work my way down.



    I didn't bother to set #1 cylinder at TDC when I removed the cam chain tensioner. I figured since I'm taking the cams off anyway that I can get it all lined up and timed later during reassembly.

    This is going to be fun!


    Thank you for your indulgence,

    BassCliff

      Hey Cliff,

      What are you riding while Jessie is down?


      Life is too short to ride an L.

          This for fun or was she getting tired?

            Subscribed. I remember seeing your bike for the first time at Bruces and took a keen interest in your remedy for oil loss, I've shared that tidbit with many a new biker that I've met I'm guessing this one will be added to you site when you're done Cliff. I'm a fan of Altoids as well.

              Excellent. I love that you are doing this. I will have to do this same thing on my bike one day, but not today.

                Cliff, I echo what tkent02 said- I wanted to go riding with you guys this summer since we didn't do a ride last year. But it's good to get Jessie all fixed up.

                  BC- your Awesome and that bike looks great- but if those parts were in ALtoids tins where I have worked, other mechanics would have used blunt force trauma on me!!!!!

                    Hi,

                    Over the last couple of years it had developed a couple of oil leaks that just kept getting worse until I finally decided to buy a gasket kit and replace everything from the base gasket up. I'll also be replacing the O-rings in the carbs, clutch springs (there has been a little slipping), rebuild the cam chain tensioner, and just generally freshen everything up.

                    It's been running great at 65,000 miles. I was hoping to put this off for another 20,000 miles or so but I got tired of oil on my boots and pants. I ride about 10,000 miles a year so I want to get it all done right while it's down. I'm sure this is going to take at least a couple of weeks between my three jobs and family. But it will be fun. Stay tuned. Thanks for watching.

                    No, I don't have anything else to ride while Jessie is down. I've got a friend or two in the area who I'm sure would lend me a bike but I don't want to ask and I would not accept if they offered. As long as I'm not riding it will be incentive to hurry this project along as much as possible. Commuting to work in my Astro van takes over $50 a week and I can do it for less than $20 a week on Jessie. So there's a financial incentive too.

                    Thank you for your indulgence,

                        Hope he manages to submit it to that rock-n-rollin' librarian guy that maintains a "little website".

                        I wonder if he is referencing that "little website" during the rebuild?

                          What material are the oil catch pads made from Cliff?

                            I like the idea of keeping related bits together. My 1000's top end is in disposable sandwich-sized tupperware tubs while I wait on correct orings.
