I didn't get much done this weekend, what with Marsden Jazz Festival and the PCGB's Peak District run on Sunday in the 911, but I did get the front end on...



What we have established so far regarding the forks is:

There seems to be a difference between CB and CL yokes, probably different geometry as suggested by K2-K6.

To add to the fun they changed the CL yokes at least twice, my parts book shows the numbers change at 1012469, which is prior to my K2 number. We have established that my bike is a K2 in K1 clothing for some reason, which suits me as it looks much better for it.

My (sold as) CB450 K1 top yoke doesn't fit. Possibly its wrong on two counts, then, CB, and K1!

Although I have a broken instrument mount, what I do currently have is a matching front end which all came off the same low mileage bike. If for example I fitted James' K1 yokes, I'd definitely have a matching pair, but mixing K1 with late K2 may not work - the forks would (probably - there seem to be different fork tops too)) fit perfectly but would the front axle or the mudguard still fit?

I think you'd have to have the parts in the same room to be sure, can someone suggest an accurate way to measure between hole centres?

You see my dilemma, however I'm not too fussed for now. My project end date is next November, the bike's 50th birthday, I want her back on the road by then, someone will break a late K2 before that date, I will be watching the web.

For centres measure from the outside of one hole to the inside of the other

If using a vernier caliper,  you can just clamp it bore edge to bore edge then add one diameter to the measurement (as you are missing two radii) that'll give you the centre to centre number.

Just turn the clamp bolts on the yokes to set the diameter to that of the fork tubes first if they've been wedged open to get the stantions out.

James, would  it be possible to measure between the fork legs, and from the fork hole to the bar mounts?

If the top yoke measures the same (also stem forward to the forks), it’ll fit if the instrument mounts are the same, I definitely can use it, otherwise no.

I need to give my yoke a coat of measuring so we can compare what we have

Dave no problem, I’ll grab the tape measure tomorrow and pop to the garage and get some dimensions...

Thanks James, I appreciate it.

I fitted the front mudguard last night, it cleaned up nicely. a bit of dirt but no rust.





Menno's box is on its way from Germany, it should be here on Friday.

Dave,

I measure the following:

Fork spacing (centre to centre): 175mm

Fork offset (stem centre to stanchion centre): 55mm (need to double check this in the am - could be 60mm)..!

Gauge mount hole separation: 100mm

Mine are definitely also 175mm between centres, like you say the offset it hard to measure. I cant measure between the clock mounts as I only have one! The webbing looks to be the smaller type too.

It looks to be the same yoke James, I'll use it if I may. I'm guessing the one I bought was for a CB450K1, that's up for sale if anyone needs one. I don't need the bottom yoke, I've got the taper roller bearing on mine, and it would cost a ton to post anyway. Let me know by pm what you want for the yoke and where to send it, Ill send you my address.

I did some fishing in the bars last night, threading the wires through after starting with a string and a nut tied on the end. After getting that though, you tie in round your wires and pull gently.





So much neater than visible wires! Early switches are nice, like most things they took a few years to get ugly.



I thought someone had painted the stanctions silver, until I looked closely and realised it was the original finish.

Rather than change both yokes for James' K1 ones I am sticking out for a CL450 K2 alloy top yoke, so I know there will be no unpleasant surprises. If you see one on the bay of fleas or anywhere else, let me know.

In the meantime the box of wonderful things arrived from Menno in Germany.

It didn't take long for me to go in the garage to find the box with the badges in,



After that, you try stopping me trying it on!





As the bike is being built in a location officially described as 'in the way' I am forgoing fitting the back wheel and engine for now, just to keep the project managable as I move it around (and around it). You can imagine how tempted I am to put the engine back in and those lovely pipes on though.

Looking great Dave. Who did the seat re-cover for you with the metallic piping?

Another shot showing the seat with the tank, it came new from Texvina in Vietnam, James, its extra with the silver strip, if anyone orders, the cheaper priced version doesn't have it.
