Aye. The only thing in the kit I've found useful has been the spark plug tool. a regular 18mm one won't go down in the hole and reach the plug. Like a lot of other folk, I've got a "Heinz 57 Varieties" tool box... some Snap On, some Williams, some Craftsman, some Mac and a lot of no name tools. If they work, I'm not impressed by the name on them.
I've got a rather extensive collexion of tools, but ran into a problem today for which I had no tool. Somewhere along the way, my right side bar end weight went away taking the long screw with it.
I tried in vain to get the shorter of the two rubber plugs out of the bar. Just inside from the weight, there's a rubber sleeve about 2" long with a steel sleeve inside it.... I got that out. Then there's a short rubber plug about 1/2" long with the locking nut behind it. The nut had fallen off the end of the screw and down into the innards of the handle bar. I tried to get the 1/2" long rubber sleeve out so I could fish the nut out with a magnet... couldn't budge the bloody thing.
I ended up taking the other bar end weight off, removing both plugs so I had a hollow bar... Then I took enough stuff loose to tilt the end of the bar up and proceeded to fill it with lead BBs to serve as vibration dampener weight.
Then I fashioned short rubber plugs inserted them and then ran large self tapping screws in their center holes to stretch them and seal them in place, then I went for a ride to see if I had a buzz problem.
I couldn't tell any difference from when both bar ends were in place. No buzz at 60, 65, or 70, so without bar end weights, I'm good to go.
