It might help if you stated exactly what model CB750 you have. From your description I'm thinking CB750F - F3, or K7/8. If the bolts...

That sounds really good. Is that a modern Yoshimura pipe then ? So now all I need is for some kind person to open one up with a tin...

I've already cleaned it up once, with a P80 flap disc on a grinder. Then I put it back on the bike to get it running, and left it on...

Does anyone sell an oil pressure gauge kit in the UK ? Looking for a small size guage that will fit at the end of the oil gallery on the...

Same thing happened to me with a scabby GS550 I bought a couple of months ago. I was so thrilled to get the thing and another bike in...

I'm in the same situation at 66, I'm wondering just how many motorcycle summers I've got left in me. I might feel a bit better if...

Any idea what make of pipe this is ? It was fitted to my US import K4, but the cylinder head fixing is the F model/K7 type, the K4...

Many thanks ! I thought that O'Reilly only operated in the US, but a quick Google search reveals apparently 500 stores in the UK. Well...

They will turn up eventually if you wait long enough. Just how long can you afford to wait ? Twenty years ? Of course after you have...

I just hate paying good money for cheap junk ! Only about nine months ago I bought new fuel pipe in order to get my F1 and K4 (ish)...

Maybe. Can you borrow a pair of coils rather than buying them ? I'd look at the condensers too, I've known them to do weird heat...

Thanks for that, I've screenshotted those pics for future reference. Those F2 brackets are absolutely enormous. The Errol Flynn of...

Sorry to hear that those K7 type headlamp brackets can't be modified to fit, as used ones seem to be going quite cheaply here, and...

I'm having second thoughts about my F2. I originally only bought the beast because it was local and cheap, and would make a good source...

I'm undecided about how far I want to go in making my CB750K1 as original as possible. At present I've gone as far as the correct...

I think that maybe you're out of luck with that one. The forks on the CB750A would seem to be related to the CB750F/F1 and also the...

I read recently that setting the idle speed too low is a major cause of cam bearing wear on these engines. I've no idea if that is true...

It does make you wonder why Honda didn't just uprate the studs in the first place, rather than introducing seals that would mask the...

That was the next question I was about to ask, because, yes, there's silicone sealant between the cylinders. Oh well, too late to weld...

Thank you ! I'll use those photos as a reference. I've already noticed something about the 72mm barrel. The "wells" around the cylinder...

Unfortunately, I only bought the cylinder. I appreciate that there's loads of research and planning (and spending) to be done before...

Getting bigger ! Now I've got 61mm, 67mm, and 72mm to choose from. The biggest bore barrels are going to present a significant...

Thanks for that ! I'm old, and I appreciate a fat torque curve more than big horsepower figures at high rpm. I appreciate that there...

Well TBH the bores on that big bore barrel are not exactly brilliant. No deep scoring, but plenty of light scuffing. It's going to...

Successfully uploaded at last ! But I'm not sure how I managed it

I was watching a clip of a dyno run of a 1032cc bike in the US. A reliable 95 BHP at the rear wheel, with an externally standard looking...

Thanks for that. They are selling on ebay UK, at surprisingly low prices. I'm glad that you posted that, because I until now I thought...
