You're pretty good at locating parts Teddy.  Looking forward to seeing how this turns out.

No kidding.

Thanks for the support. Yes and also about 1200$ has so far been invested in parts, with a lot more to come. Now i need to get the engine checked soon, to see if I also need to source an engine.

Update 31st of October 2021


Found a pair of okayish gauges. I think these are 1974 period correct? With some rust removal, polish and paint I think they will look okay for a decent overall cost.


There is a bracket that makes it quite easy to seperate the pieces of the gauges. Somehow I think not all years had this?


These tripple trees are not easy to find. This one looks ok with no cracks, but there is a broken bolt in the top, which I need to extract. It was accompanied by two re-chromed brackets which look quite good.

Look OK for Swedish K2 that was actual between 1972-75.
Probably same in Denmark

USA got other gauges from 1973, model called K3 and look like our K6 except for petcock still as K2.

Update 3rd of august 2022

So finally I got some work done to replace the wrong components to make the bike “almost correct”.
Note that the bike is a K4, but in Scandinavia this would have US K2 specifications.
I replaced wheels, forks, shocks, fuel tank, triple tree, front brake valider, seat, fenders, headlight, rear light, gauges, mirrors, side covers, ignition and some smaller stuff. Still have a set of indicators to mount, but am missing the seat bracket. Still a long way to go… Look forward to sort out the wiring and see if it will start.

wow, nice work!

That bike reminds me about the first version of my CB750 K6 (avatar bike) at its comeback on the road 2014
A really nice feeling to ride it again after 24 years. (parked 1990)

The upgrades continued  after that and still coming. This forum is a dwell of knowledge, good ideas and other good builds!

Yes this was parked since mid 90's...
This bike seems to be Japan produced 1974, which is not the model sold in Denmark during that time. So it must be imported. Also first registration happened in 1978 in Denmark, so somehow it was imported then.
I am a little in doubt if I should go for correct K2 or K4 specifications. K4 would be easier, but I like the look of many things from K2 better actually.

K2 speedo and tacho plus the upper triple tree are not cheap.
You need kmh speedo too that is not that common for sale either.

K2 version has different battery holder with additional electrical stuff. Only 1 fuse.
K4 different, as K6 in Europe.

But the K2 look might be tank graphics only, right?

I wish I had seen this sooner. I know you are trying to get back to something closer to original spec, but you could have retained the superior twin disk front end and still used the wire wheel that you have on it now. With the forks properly installed with the calipers in the back, you can use CB500/550 rotors with the standard wire wheel (the hub is already set up to have 2 rotors) and then just need to shim the calipers a bit to get them properly centered. I upgraded my single disk 750F to dual disks this way. Here is a picture. I have Lester rims, but the spacing is exactly the same as the wire wheels. Strip the black paint off the lowers and they would look very similar to the original fork.

Which year 750F is this one Danny ?
