    Believe it or not, aluminum foil does a great job at removing rust. A bit of oil on a sheet of aluminum foil and pour on the elbow grease. After that, some #0000 steel wool then follow with turtle wax chrome polish. Worked well on my Jardine exhaust.

      Not sure what I have.

      The serial number on my xs11 is 2h7100904.

      The frame says it's a 78 but I'm not 100% sure on the model.

      Any help is appreciated.

        Stan, if you lookin the FAQ section of the site, there is a htread on identifying your XS11 by the Vin/Ser number.

        link

        looks like you might have a 79 Standard.
        Life is what happens while your planning everything else!

        When your work speaks for itself, don't interrupt.

          Hmmm...interesting.

          Thanks for the link.

          It seems I have an interesting thing going on here! I agree that the serial seems to say it's a 79 but the manufacturers sticker says January of 1978.

          Could this be a date of manufacture and Model year difference of information? That is to say, it was built in January of 1978 as the model for 1979. Could this be what I'm looking at?

          Thanks.

            Model years for bikes are different from cars. The date of manufacture does not always indicate the model year. Always go by the serial number.

              The serial number 'break' between 78 and 79 given in the link may not be right; I've got two '78s, but according to the link one is a '79. The latter was built in 4/78 (still well within the 78 model year) and is equipped as a '78'; it has the 'tube-type' wheels (with the rear 'bead locks') and the sealed-beam headlight. My other '78 was built in 12/77 (one month before Stan's) and has the 'correct' serial number.

              In either case, Stan's bike is a 'standard', not a special.

                  Actually cars are the same way. Its a vehicle thing. The model year generally starts at the end of summer or early fall. My 89 Camaro was actually born in late 88, but it's an 89 model. I almost bought an 80 model chevy brand new back in late 79, but changed my mind when they decided they wanted $600 more in down payment on it. I'm glad I did, it was one of the ill fated x-body's that they had nothing but trouble with.

                    What year is my XS1100?

                    Hi guys.I'm confused over the correct year for my bike.The engine and frame numbers are the same (3X1-000264).
                    But when I was having trouble with my valves I got some inlets for an 1100G 1980 but when they arrived they were too big.I discovered that my engine appears to have the smaller 1978 or 1979 inlet valves.
                    It's registered here in nz as a 1980 G but now I am not sure.

                    Please enlighten me

                      Here's a link to ID your Eleven:



                      Looks like you have a 1980 Oceania model and as far as the smaller valves are you sure the head is original to the bike ?

                      1979 XS1100SF (stock-euro mods planned)
                      1984 XV700L Virago (to be hot-modded)
                      1983 XJ750MK Midnight Maxim (semi-restored DD)
                      1977 XS650D ( patiently awaiting resto)

                      Sometimes it takes a whole tank of gas before you can think straight.
