Honda CB750K5 Restoration by Royhall
royhall:
Thanks for trouble shooting guys, There are a couple of issues to address before I move forwards with it.
Johnny. Your right about the big washer, the parts book shows it as fitted to the other side of the shock. I will address that when I drop the swingarm again to take all the powder coating of the frame around the bushes. The swingarm works just fine as it is but I'm not happy with it.
Lobo. You must have eyes like a shit house rat. I didn't notice the short of one thread on the nuts when I was assembling it. The problem appears to be the new genuine Honda nuts. They came in four bags with the correct parts number, but when I compared them to the old rusty ones just now they are about one thread thicker. So that's the issue. They can stay like that as all the threads on the studs are used correctly. The other issue you mentioned was an O Fu**ing Hell moment. Yes, I have forgotten the earth strap, and worse I haven't removed the powder coating either. I will see when the swingarm is out if I can open up the frame a little bit so I can get a thin file in there. Failing that, can you post a picture of your fix.

Roy,
the nuts that came from Mr Silvers for my ear sprocket were short a thread too. They're on and staying like that but I had to do the same and check them against the OE ones that came off it.
Bit odd? they were in sealed factory parts bags also.??
Lobo:
…interesting how thicker nuts are now supplied; guess accountants involved and using a one-size-fits-all approach?
Wrt the earthing, I genuinely submit that leaving the frame pristine in the original frame-engine earthing area will save you possible corrosion issues down the track - this area is pretty inaccessible once the bike buttoned up. (Of course you will still need to strip the frame of ‘coat immediately under the battery earth strap)
Through necessity (😬) I used a front mount, and as said, am much happier as now I can keep an eye, and better still, easily fettle any bared paint corrosion should it start. The powder coat has been carefully removed under the head of the marked bolt. You can easily guess, I don’t intend to have this bike apart anymore within my life!
(Comment… we ride in different climates; my bike never gets wet and this bolt is obviously more exposed. Otoh, the ‘OEM’ area may be wet at times too I guess.. just less seen!)

Thanks for the feedback, those small issues will be sorted further down the line. In reality I don't have much choice about that as the bike is way ahead of the forum write up, so some reversing will be required. It will get done though as it needs to be right.
Before I turn my attention to the front end I have got some of the back done. As I always do, before fitting the mudguards I sprayed the insides with a liberal dose of cold galvanise spray. I'm not intending to use it in the rain but sometimes you get caught out whilst out on a run so thought I would give them some protection. It can't be easily seen from the outside but looks fairly neat anyway.

The back mudguard fitted. The chrome looks a really good job even covered in greasy hand marks.

Turning now to the front end a problem soon became apparent. I had previously bought a set of fork ears from Silvers at just short of a "sack of gold" as mine were badly twisted and dented and more than a little rusty. When test fitting the rubbers gaiters it was clear that the trim ring would not fit. I tried the gaiters on the old ears and it was all perfect so clearly the problem was with the Silvers ears. As usual Silvers disputed this and said they tried all their stock and they were okay but they would accept a return and refund so happy days. These are the pictures of the silvers item and genuine.

So not wishing to order the same again I thought I would give the Dutch suppliers a miss and order a set from Yamiya. After parting with "two sacks of gold" they arrived. The quality of the Yamiya parts was way above Silvers items and guess what, they fit perfectly. They have added to the bill but at least that problem is now solved.

Quite annoying! It beats me that when some of these replicas are produced that the manufacturers fail to get dimensions right.😡
Coming along nicely Roy! On target for a spring time road run?😜
