    Those looks like nice tools. A regular tap should work too. With a tap you have to be very careful not to cross-thread it. The linked tools look a lot safer to use.

    Screws sourced here in the US (ANSI/ASME/SAE metric) may have different head sizes than other screws of the same nominal size on the bike. I'm not sure what you'll find there, or if it matters to you. For a "stock" bike, I hate the idea of a wrong screw, and I didn't want to have to carry another size wrench.

      OEM Exhaust back on my GS1000G

      Well after 30 years with the O'Brien 4 into 1, I now have the OEM system in place and she looks like she is supposed to be.

      All new gaskets and half shells on 2 and 3.

      The original jetting wasn't changed and the bike seems smoother and has more grunt from 2,000 rpm and beyond.

      Much nicer to ride around town and highway roll ons in top gear are considerably easier.

      Sorry no photos at the moment Photobucket seems to have an issue with my uploads.

        The 4 into 1 exhaust was a cheap replacement when the original rusted out. It was considerably lighter and had a deeper note.

        The OEM system looks right with a muffler on each side and the manufacturer obviously designed it with the best compromise between performance and the legal noise requirements.

        When I bought the bike new in my 20s I understood little about motorcycle performance or the long term desirability of an original bike. At 60 I'm still riding and enjoying it. I've dismantled just about every part except the engine and forks. New fork seals and maybe fork springs are next on the agenda after the current tyres and front wheel bearings are replaced.

            Not that I don't like a good ass picture... but how about a side one. Great picture though, nice rack and all...
