750 K7 Exhaust Collets / flanges
« on: September 25, 2021, 03:43:20 PM »
A long shot I imagine but on fitting a new set of 4:4 repro pipes I have found that I need the eight split collets that fit at the top of the pipes at the manifold.
I had some which I was given together with the collars however they are way too shallow - so obviosly not the right ones!

Does anyone have some spare or know of a place to get them? I have seen them on Silvers website but they are pretty expensive when you need eight!
Maybe there is an alternative that would fit this exhaust that someone might be aware of?

Any suggestions? Thanks so much.

Sorry you are stuck with Honda for those as earlier 750 had spigots

It could be worth getting the part number and trying your local Honda dealer, frequently same price as Silvers but no postage

post a pic of the ones you have. i once (and someone on here) fitted them the wrong way round and didnt fit, obviously.   also, do you have the copper rings in there first?

Thanks folks... all advice happily recieved. I'll definitely try my local honda people as well.
Ive included a pic of the ones I was given but they are definitely too shallow! Oh yes, I do have new copper rings but thanks for checking.

I'm also happy to offer these collets to anyone who might be able to use them!

Thanks Bryanj for the tip on a supplier. I had wrongly thought that I would ONLY get them at DS but after reading your advice, I tried my local Honda dealer (Fowlers, Bristol) and lo, they had them in stock, same price as DS and free postage! So, still extremely expensive for what they are but a good result nontheless!
Bits arrive tomorrow so back to fitting the pipes now!
All good things

This appears to be the correct collar and the correct way round!
Correct me if I'm wrong please!
