    Repairing the chain adjuster

    My chain adjuster had been given a good dose of Bubba. A previous owner had used what looks like a screwdriver and lump hammer to adjust the chain. Half the teeth were butchered so badly the adjuster was jamming against the swinging arm.

    ​​​​​​I have removed the eccentric hub to recut the bubbaed teeth with files and a junior hacksaw. One of the teeth was so bad I didn't dare cut it back properly or it wouldn't have been anything more than a bump.

      The eccentric hub now turns in the swinging arm very easily even without any lubrication. I need to check with the manual to see if it's fitted dry or greased. The hole for the hub and the hub was full of black goo but that could be chain lube that's leached into the swinging arm.

          Nice work.

          Every time someone suggests using a screwdriver to adjust the eccentric, it drives me mad.

              One of the rear caliper mounting bolts had been got at by Bubba. For some reason the bolt head had been ground down so there wasn't enough to get a socket on. I had to use a Propane torch to break the green loctite before I could shift it by walloping it with a drift and a big hammer. I got a lot of anger out on that bolt.

              This is the two bolts side by side.

                  Geez... be very careful taking the sparkplugs out. Bubba is never a once or twice even. It's a lifestyle.

                      Holy cow that makes my eccentric look fresh out of the Honda factory. The proper wrench costs a few £$€ and a plastic drift costs pennies.

                          Oh the centre spark plugs were rusted in place I think they were the originals. The best Bubba so far is the tank mounting rubbers had been replaced with cardboard. Luckily eBay came to the rescue though they are slightly perished.

                              I think there are still some fresh new rubbers available from the group buy?
