Choosing a cb550 donor bike

Plus the 550K models have the raised fuel cap, something you said you are looking to avoid.

Doesn't a k3 have a concealed cap though?

Yes, the K3 has the concealed cap, same as F1 & F2, it's the same tank. The tanks with the flap look nice on Custom bikes, gives a nice clean line.

I thought so, yes I really like the shape of that tank

I used a 500 tank on mine as I had it already but if I had needed to find one, I think I would have been just as happy with the flap type.

Yes the K3 does Dom, but the 550K0, 550K1 and 550K2 had the old style raised cap, hence why I said they weren't what you were looking for.

You can easy use a CB550K0, k1 or K2 and buy a F/ K3 tank . I have a 550K1 with a F2 tank fitted.

No you can't, it doesn't fit. The seat isn't compatible with it, it's been discussed quite a few times and I tried it on my own 500, I seem to recall the tank is longer and the seat fouls it. I'm sure someone else will confirm. If you have an F tank on you have to also use an F type seat. Or even a K3 seat

DOM has said that he wants to do a cafe racer so, a cafe racer seat a different seat 

[DomP]

Yes that's a good point Trigger, any 550 will do in that case although finding one complete with the right carbs and tank might be the most straightforward option

My 550F is still for sale , look in member sales 

Thanks Dave, I've looked at your bike but you've done a lot the bits I wanted to do so it wouldn't be much of a project for me except stripping the engine paint back.  Who knows I may change my mind
