CB750 / Re: Major problem fitting exhausts.

There aren't words to explain how embarrassed I am right now. And relieved!  Yes it fits fine now.  THANKS SO MUCH!!!

Thanks for the quick answer. I've attached a photo of the problem.  Believe me there is no way the rear mounting point is going to line up. I started this project about 10 years ago and memory is fading now. But I do remember getting a new cylinder head (and having it blasted and painted) as fins were broken on the original. Now I'm wondering if I ended up with a cylinder head from a K7? Could that be the problem? If it is - it's out with the engine again and I'll be looking for a new cylinder head.

Regarding the rear footpeg - I can just drill that out to the larger diameter to fit the supporting bolt so a relatively easy fix. But a new cylinder head! Damn!!!

CB750 / Major problem fitting exhausts.

So - feeling quite depressed now. I couldnt seem to make the new exhaust system for the K6 line up with the rear mounting point once the end was in the cylinder head.  Have just checked the part numbers and two of the pipes supplied have different part numbers to the K6 drawing / parts list (the two without the decal that screws on). Checking part numbers the system I have is for a pre-K6 model. But the question is - is a K6 exhaust system different in terms of dimensions to a pre-K6 version. Or should the exhaust systems be interchangeable?  The photo shows the part numbers I have.

Also, the main supporting bolt at the rear is too large a diameter to fit through the rear footrest brackets. However I bought the footrest brackets new from the K6 page of CMSNL - so this is all getting very strange.

Hopefully I'm doing something stupid. That wouldn't be the first time. But has anyone got any ideas?

Oh thanks. I put those in ages ago so didn't recognize them. I wonder why DSS supplied those as part of an exhaust fitting kit? Anyway. Mystery solved. Cheers. Phil

CB750 / Where does "bush rubber B" go on the exhaust?
« on: July 14, 2020, 11:41:12 AM »
Hi. So I'm back with a question. In the David Silver exhaust fitting kit I have two rubber bushes part no. 40548-268-000. However on the exhaust system drawing / parts list (from CMSNL) I can't see that part.  Any ideas where those should go? Photo of mystery part attached.

Thanks. Will post a photo once done. Cheers. Phil

Hi. I'm at the very end of my K6 project (10yrs!) And about to install the exhausts. I bought a brand new set of factory pipes from Honda when I first bought the bike plus a fitting kit from David Silver Spares (all Honda bits but they put everything in one bag). See photos. Everyone has been so helpful as I've put this together I just so here's if there are any "top tips" or things to be careful of before / as I install.  I guess they are worth quite a bit now so don't want to mess them up. Any help much appreciated as ever. Phil

That's really helpful thanks. Looks like it will be relatively easy to make something that will do the job while I look for the real part.

That's so helpful. Many thanks. Anyone have one of those brackets they would like to sell me :-) ?

Cheers.  Phil

CB750 / CB750K6 crankcase and cylinder head breathers
« on: July 11, 2020, 07:21:31 AM »
I'm having trouble working out where the crankcase and cylinder head breathers route on my CB750K6. The parts list has a breather on the crankcase (12mm dia x 185 long) with spring clips on both ends - but not obvious where the other end pushes on to (the K6 oil tank doesn't have the pipe on the oil tank the earlier models had). Similarly I'm not sure where the cylinder head breather should route (and not sure how long that pipe should be). Any help much appreciated. Phil

CB750 / Re: CB750K6 restoration project. Disc cover fowls on disc
« on: July 05, 2020, 05:03:46 PM »
Yes. Bought from CMSNL. There was no cover on when I bought it though. I'll check the disc diameter. That's likely to be the problem. Cheers. Phil

« on: July 05, 2020, 02:46:40 PM »
Yes there is. It came with a twin disc conversion - I've left the RHS disc off. So I guess it must be a set of 750 forks. Maybe the disc is non standard and diameter slightly too large? Anyone know what the diameter of a standard disc is? Thanks again. Phil

Yes - that's where I'm trying to fix it. The more I look at it the more I'm thinking I've got 400 forks on it. Does anyone have a measurement from the center of the front axle to the point where the rubber gator starts on the the LHS lower fork section?  That would be really helpful. Thanks. Phil

CB750 / CB750K6 restoration project. Disc cover fowls on disc
« on: July 05, 2020, 01:12:03 PM »
Hi. Hoping someone can help me. I'm at the very end of a restoration project on a K6 and tried to fit the disc cover - but it fowls on the disc. The disc appears to be the right size as it just reaches the top of the pads. I'm wondering if I have a pair of CB 400 lower fork sections - which could have the mounting brackets for the cover in a slightly different place?  Or am I missing something easy?  Everything else appears to line up / bolt on perfectly.
