    I may get them welded in yet, depends on my mate getting access to aluminium welding gear. I can weld aluminium but I'm in the same situation:D BUT when you consider how far the exhaust pipes go in I think I could get away just clamping it. Given:D that I'm fitting reverse cone megas I don't think the noise will be an issue:D

    i'd seal that off if i were you. you wouldn't want to have any air leaks there, resulting in backfiring and leaning-out of your mixtures (add to that the difficulty of tuning the carbs).

    I put Walter's exhaust nuts on my '89 R100GS over the winter when one of my exhaust threads was damaged. They worked perfectly but I think the nicest thing is that I can use an allen key to remove the exhaust now. That's nice when on the road...

    By the way, Moneybookers worked just fine.

    ... a quick bump for Walter's exhaust nut adapters :thumb

    I didn't have any problem getting through to Walter by email, and he always replied to my questions promptly. Also, I didn't have a Moneybookers account and didn't fancy setting one up but Walter was happy to accept Paypal.

    The only minor issue I've had is that it took 3 days from posting for the adapters in the father-land to them arriving in Oz and then another 17 days to traverse the land down under ... go figure :huh

    Good communication, quality product ... delivery within Oz via Pony "express"

    Have a good 'un

    How in the hell did that happen? Was anyone hurt?
    That will leak like crazy. and may cause further problems down the road/ keep in mind that the compression ring and seal ring are being drawn up to the face to seal exhaust. don't want to burn a valve.

    sorry to dig up an old thread, but i just installed one of these doo-hickeys and it worked like a charm. had to cut off my old finned nuts and looked like a previous owner basically glued them on with some kind of adhesive as there were barely any threads there once i got them off. researched around about getting new threads cut in and stumbled across this easy fix. for around $120 i'm back up and running, although they do look a little "odd." maybe someday when i do a restoration i'll get them properly fixed and new threads cut.

    anyway, ordered them from the UK and they were at my door within a week. http://www.motorworks.co.uk

    and they also make a "finned" version now, but i didn't want to pay the extra money for them.

    just wanted to bump this back up from the depths and leave my positive thumbs up to the original creator of them:
