to all out there with rotten exhausts. I've just purchased a set of stainless steel downpipes for my 750 from delkevitch.co.uk
the 1988 CBR100 F-K ones and after a few modifications they fit. Firstly you have to remove the lower brkt then weld a piece of stainless approx 140mm to the underneath of the bracket even out the distance from each side, then the headers have to be taken down by approx 1mm, I did this with a small grinder and removed enough material for them to fit into the cylinder head, next bolt the exhausts up to the head and then fit the bracket to the original mounting point and then you have to form the plate that you previously welded to the bracket to make it fit onto the collector box. You can then either weld the bracket on in situ or remove the downpipes and weld the bracket on (much easier) after this you can fit the pipes. as for the silencer I have fitted a venom silencer from a FJ1300 to the rear hanger and then made a template and then I got a transition pipe (2" stainless) bent up (thanks to the guys at work) and at the same time get a small length of 2" stainless approx 50mm long and get a cap welded on it. Fit this blanked pipe into the L/H outlet and fit the transition pipe into the R/H outlet and into the silencer and that's it job done, you now have a nice new stainless system fitted to your 750. you can use any silencer you want but you will just have to get the transition pipe made up to suit. I hope this helps??

Well done, that is one thing you won't have to worry about for the overseeable future :zaehne009:
I do have such a Delkevic headerset myself, as I have an '87 1000 I only had to reposition the rear brackett, tacked it on in situ :uptosomething: and welded it proper after taking the lot off again

I've been looking, but my old pics of that operation aren't on the site anymore, thanks to some 'updating' by our webmaster (who's now on holiday, so I can say what I think of him without fear :lol: )

I came by just 1 pic, while cleaning up my harddisk, here it comes

I can't remember 100% but i think you're right. I did look through the main site thoroughly but it's not there. Maybe it got lost when i added the youtube button that crashed the site long ago and made me do everything all over?
Anyway it's there now.

hi,
I got my exhaust from Sandy Spares. it's a 4-2-1.
I've had to cut off the original bracket and weld a new as it was in the wrong position.
it's ready to fit now, and I'm just wondering if anyone has any tips for keeping the gasket rings in place when fitting??

cheers!
Barry

Those rings should be a tight fit, and stay in place if you properly push them in, if not you can put some grease on to 'glue' them where you want them. Nice looking pipe it is, it's better to weld a brackett in place then having to weld holes shut in a rusty pipe! :thumbs:

They ARE wider than the exhaust port I hope, or you'll have found another way to restrict your bike :uptosomething:

they're wider all right, but not tight like the ones I had to remove with a sharp chisel :smashfreak:
biggest restrictor on my bike is me! hopefully one of these days I'll put the bike back together again :grandpa:

Relax, I suppose I'm the  :grandpa: one here, and when I started riding in the early seventies, the bikes were the restricting factors, with their elastic frames and wooden tyres.
Today the bikes are so much better, as are the tyres, that they can handle more than I dare trying out, and that is a good feeling!

ok, well I was only a glint in my dad's eye in the early 70's :schilder034:
I'm a '74 baby :birthday:  though just back from table tennis tonight, and my knees are feeling 74 :grandpa:
hey, ever see the film 'the world's fastest Indian'??  classic! gives a whole new meaning to growing older!
