  1. Hi there,
    I'm relatively new to netrider but have been around bikes a very long time. I've recently bought a zephyr 750 as it fits me and what I want to do on a bike these days. However it is totally stock, and while that is nice in its own way I really would like to personalise it a bit. It will soon have Promecha tweaked suspension front & rear and a few entail bits too. What is proving difficult is finding a 4:1 pipe for it. I started road riding in the early 80s so although this bike is a 70s throwback I would like and 80s style muffler. Anyone got any good ideas where I might source one?

  2. Might be worth seeing what the shipping charges would be from the UK on a pipe as the Zephyrs were much more common there than they seem to have been here, and UK rust problems have always ensured a plentiful supply of aftermarket pipes for most things, even quite old stuff.

  4. Megacycle engineering 0402 905 523 there in Summerville, the last of a dying bread, makes a good product

  6. I had a look Pat, but I think the delkevics look best so far. I did find cafe style mufflers from Voodoo in the US that look good too.

  7. Ok so I bought the Voodoos and although they look good I'm not sure they suit the bikes style as well as I'd hoped. So I got a Delkevic shorty cafe style 4:1. It looks good, all stainless and fitted up reasonably well. The best bit is that I can retain the centre stand. Unfortunately it is VERY loud. Too loud for me. I then purchased a Db killer that I inserted down the muffler. This has shut it up a bit, but I think I can get it better. Once I get the noise level right I'll send it off for jetting on a dyno'.

  8. Cool bike, I had a Zephyr 750 & just put on slash-cut harley slip on's in place of the std exhausts, was a bit loud, but heaps lighter & neater.
    There's a pic of it out on the internet from like 2003, lemme see, here:
    zephyr1a.
    Alpine way Victoria somewhere. Oh yeah, I had ace 'bars on it too & that tail tidy was a backyard job - I bought a rear fender/plate holder from the wreakers & hacksawed the whole bottom half off. Phuck that was a good bike.
    ...Oh yeah, a cheap little handling trick: if you look at my rear wheel cam-axle adjusters (for chain tension) you'll notice in this pic that I have them spun 180degrees so the off-set axle centre is towards the bottom - this picks up the rear end slightly & makes is handle a little sharper than stock.
