CB500/550 / Re: 1977 CB550f parts questions
« on: January 15, 2019, 06:07:09 PM »
F2 came with blue faced clocks the same as the ones fitted to the 550K3. The F1 had green faced clocks. If it has original paintwork the F2 had a flash decal on the tank and metallic paint , the F1 was a flat paintwork model with no decal.

I have a V5 with my L reg 500 on it. It's not been on the road since at least 1980, well before SORN was introduced. According to the DVLA the last time I checked I was not entitled to the reg number as they no longer have any record of it, seems they converted the old records onto the computers they use now and as it wasn't in use at the time they didn't transfer it across. They did say I could ask if I could reuse the same number but I had to have permission off the HOC first, no idea why the HOC has got this sort of power. The number is not in use by another vehicle as it doesn't show any result when you try the site. You'd think the fact I have an original V5 would give me the right to the number wouldn't you?

No idea Bryan, not stamped AFAIK and no stickers attached, remember going into some bike shop somewhere and buying a set and they asked me if I was interested in buying all the remaining parts for them as they were no longer interested in selling them for the 500/550 (most likely because the model was no longer in production, was the later 70s) I bought around 3 complete sets and a few of the link bars which go under the carbs along with some other bits. I sold most of them but still have some loose bits to this day.

Tower doesn't ring a bell though, might be wrong though, seem to recall they made carriers etc.

This is a better pic of the bars.

Got me wondering this question so I dug out a old photo of when I was restoring the L reg 500 and as you can see I went for the long angled red NGK cap on the outside cylinders with the straight ones on the inside. This pic was taken in the very early 80s so I could have had original caps with no problem but as you have said they were frankly awful and shorted out in even mildly damp weather, I took this bike out in torrential rain and never missed a beat.

As an aside, anyone recognise those crash bars, I had them and still have them on all my 500s but no idea who made them, still have a few pieces of them somewhere but not a complete set.

It's shown on the PDI for the 500, it's on the site somewhere.

You have to be on the left as that's where the stand has it's foot lever.

I see what you mean oddjob, you mentioned drum out of line?

Possible the drum retaining bolt was missing or very loose, this allows the drum to wander slightly. As it moves it would alter the angle the fork is presented to the gear facing, you'd then get the wear marks being at the same as what the fork I was describing. If that was so though, I'd expect to see the same marks on the other 2 forks which aren't really there.

When the centre fork arrives check for distortion and if the top looks bent.

I should have most if not all of those. I'll have a look.

Those doggies ( Forks) look pretty good to me Oddjob. I think you have been looking at too many NOS parts for too long  ;D ;D ;D

I'm not saying they are trash, I'm saying that when you look at the original auction pics in exploded view you can just see a mark starting to appear on the circular part of the centre fork, right where you would normally see a rubbing mark from the gear, the bottom of the tips have black marks on them, it looks like they've used a black marker pen to conceal something, there appears to be a slight gouge sticking up on the very edge of the black marking on the left hand fork, when you look at the reverse pic the marks are now at the very tip of the forks and again look like marker pen has been used. The fact the marking is at the bottom of the tip on one side and the top on the other may mean the fork is very slightly bent OR the selector drum was very slightly out of position.

As CL350 forks aren't that hard to come by in the USA I'd have waited for a perfect one to come up BUT saying that they were quite cheap foe all 3 even though of course the 2 outer forks are of no use to Safo, he could always sell them on I suppose and recoup some outlay.

Saying all that it's possible the marks are shadows although I doubt it, we'll have to wait and see when they turn up.

I presume you bought the forks in the link as they are no longer available?

If so wait until you get them in your hands as sometimes things look worse or better than in pics. It's not the worst centre fork I've ever seen, in fact it's not that bad but it is starting to go looking at the scrape mark just starting to show on the arm, if you've ever seen one completely gone you'd know that it's that area and the tips of the fork that show the wear the most.

The oil should be the one thing you don't skimp on with the Honda fours, as the gearbox shares the oil with the engine unlike cars any contaminants will wear the box out faster especially the fork selectors as they are constantly in mesh with the gears, contaminants act like grinding paste on the tips so changing the oil and filter on a regular basis is essential.

I'll see if I have a good second hand right hand selector fork just in case, I do have some spare forks, no centre ones though as they seem to be the 500s weak link n that area.

Typical of Haynes not to get the terminology right, a layshaft by it's definition is "an intermediate shaft within a gearbox that carries gears, but does not transfer the primary drive of the gearbox either in or out of the gearbox" as there are only 2 shafts and both are involved in transferring power from the engine to the rear wheel neither can be called a layshaft. They are common in rear wheel drive car gearboxes but not motorcycle engines, it's what you get when car mechanics work on motorcycle engines, it's easier to call the countershaft a layshaft than look up the right expression.

You do realise that there is no such thing as a layshaft on a CB500, there is a main shaft and a countershaft, I'm presuming your referring to the countershaft but by not getting the terminology right you risk asking for the wrong gear.

Looking at the pics I'd say the selector fork controlling countershaft 4th gear is badly worn, this meant that the gear became less engaged over time and eventually resulted in the dogs on that gear becoming excessively worn and eventually to start to chip bits out of them as is clear in one of the pics, it would have eventually resulted in 3rd jumping out of gear all the time. Some of the other gears are also showing the same type of wear, most likely because the oil doesn't look to have been changed too often, it's pretty rank in there. The right hand selector fork is quite difficult to get hold of these days(in good condition), especially NOS unless you want to pay a few hundred for it. The 350 gearbox only uses the centre fork and the link posted I'd personally avoid as it looks like the centre fork was starting to go on that, there is a scrape mark starting to show on the arm of the fork and there are what look to be burn marks which looks to have been disguised by the seller on the tips.

I have the left and centre forks NOS but no right NOS. I don't have countershaft 4th, countershaft 1st or countershaft 5th. All the other gears and shafts I have NOS.

Sorry can't work this out. Problem with 3rd yet your looking for 4th gears?

I have almost a complete NOS gearbox for the 500 including 2 NOS selectors but not sure which they are, one is certainly the centre one but the other could be left or right. I could look if your interested.

If you have a parts book list part numbers instead of descriptions as it avoids confusion.

I can find the ignition switch Bryan but can't see where Emgo just make the plastic part, can you post a link I'd like to refresh my memory on how they clip onto the barrel.
