Please see: http://www.sohc.co.uk/index.php?topic=2586.msg7389#msg7389Also: I posted this on another site : Back to the clear covers. Please don't mock the following  Bought a child's skipping rope which had PVC outer tube for 2 GBP. had it analyzed as well as a '69 Honda terminal cover and basically the same PVC except that the skipping rope one had a child friendly plasticizer in it. But the OD and ID were too big. Heated it up whilst stretching it to achieve a narrower OD and the right wall thickness, then quenched in cold water. Cleaned the bore with isopropanol and dried. Then used my daughters old hair crimpers and managed to fuse the sleeving end to a piece of old Honda loom cable (the temperature needs to be just right to soften the PVC but not degrade it). I just need to make the right heated aluminium platens on my lathe to give the correct profile. then they will look just like Honda 'fused to the wire covers' (female bit of bullet). I will post full details and pics when I have finished it. I was born in the early 50's you know and we had a 'make do and mend' philosophy drummed into us in the UK !! Ash D

I have these but not sure if they are F1 type. they have 392 on the Skirt and HONDA ( approx.1.1mm top ring)
Also, see

The piston in the background is also a 392 but has the thicker rings and different top profile - pretty sure its off a K7

Yes just the sleeve.
The Babyliss straighteners get far too hot and the other temperature controlled ones we have are kn*ckered so I am going to adapt the elements from the kn*ckered one onto a temperature controller and try that (I run a small electronics design and manufacture business so I have plenty of parts). will post my findings.
I am setting myself a weekly targets on the K0 and this week's target is to refurb the wiring loom without spending a hundred quid!!

Hey - just looked on CMS website at the feedback on a new K0 wiring loom (actually a '341' loom) and someone complained that the twisted and soldered wires inside the loom (i.e. under the tape wrapping) were found to be twisted together but not soldered. Imagine having to track that one down. it was described as manufactured by Honda but a repro and had Honda P/N Just tring to modify an old pair of hair straighteners ( as you guess I have teenage daughters  ) to make a rig to fuse together plastic sleeving to get the original look on the connector sheaths. Anyone know where you can get transparent sleeving from of the original size? Also worth remembering on looms where connectors are tinned that you can clean them up and then dip them in the dip type tinning solution used for PCB manufacture (Printed Circuit Boards) to replate. I did this on my 400/4 loom back in 1986!!

Anyone know how many dark green wires are in the main loom which going into the headlamp bucket on a K0? I suspect two, which each go into multi way female bullet connectors. found this which is really good http://oldmanhonda.com/MC/wiring750K1.htmlAnyone got a hi-res picture of an unmolested K0 loom? As you can no doubt guess I am currectly rebuilding my original loom

I have had a CAD drawing done for an oversize caliper pivot pin for the CB750K0/K1/K2 if anyone is interested. I am getting on made in Stainless Steel and reaming the hole in the arm and brackets out to 11mm. the standard pin is NLA from Honda and I don't even think Yamiya sell a repro one See http://forums.sohc4.net/index.php?topic=30553.0

See my earlier post http://www.sohc.co.uk/index.php?topic=2398.0
However, for rusted bolts in the frame then probably heat and penetrating fluid. Be careful not to crack the engine mounts as I got a parts bike (K7) and a spare set of cases which had damaged engine lugs. I was lucky, as most of my engine bolts had been replaced with studded bar which did not seize (had to buy new bolts though!!).
You probably know already Jock but the sister US site has a wealth of postings on it. I just wish that 'Hondaman' on it would get his book finished!!

The best think about your bike is it's a Genuine (Oval rear lamp) CB750 or if a later one a genuine rare K0. Sandcasts were never sold here so I can't really see why people in the UK wax on about them (unless they are treating it as an investment). Think of the history and stories of that bike. Some guy and his wife using it for their sole mode of transport for years on a Scottish Island. I bet there are many tales to be told about it's history. Imagine in 1970 it's appearance there, where it would have been admired by schoolboys but told it was 'Jap Crap' by old A10 riders. Maybe, we should have a 'Who do you think you are' TV program' for vehicles.
Enjoy the restoration in your retirement and take your time. Then when it's finish go back with it on holiday to the Island it came from.

Over to you on frame number Jock. From what I remember of the Ebay listing it was later in 1970 ish.
My advice would be to strip down to the bare frame, have it blasted and see what the corrosion damage is.
And throw NOTHING away!!!
It looks pretty much standard to me? Does it have a 'wrinkle' tank? Mine is Oct '69 and does not although I am sure it is the tank it came to the UK with in Jan 70 and had the Alloy filler cap and early badges.
Guess you are going to need new shocks!! - Just got mine (Honda K0/K1 version) from Silvers for 250 quid. Ouch!!
Good look and we will help you as much as we can!

It also looks like it has the Sandcast Oil filter housing which was a recall issue. Yes the shocks were wrong too - Just bought mine from Dave Silver - my Christmas present to Myself
