Mike's CB550 Project

Looking very nice Mike. I gather that James came through on the ignition switch bracket then.

As for why the field coil isn't showing magnetism, do you have the rotor cover with the separate badge or the cast in badge? The separate badge could be masking the effect due to it being alloy, you could try removing it and testing again some time in the future, not worth doing it now as it's a bitch to get off without damaging it. Rotor cover needs to be off to get it off without damaging it TBH.

I could do with that number plate, half my forum name

It has the separate badge but it’s not fitted; still no sign of magnetism. Once I get it out on the road I will find out if it really is charging properly. Yes, James got back to me thanks.

That really does look a lovely fun bike Mike.

Nice job, Mike. I shouldn’t be too concerned about charging if it’s knocking out 14V or so.

I took the bike out for its first run today - a short trip up and down the hill apposite our house - maybe a mile and half max. the bike seemed to handle well, nothing fell off, lights worked, brakes worked too although the single front disc is not quite as effective as the Brembos on the front of my Triumph Tiger. 4 into 1 Delkevic sounded good and so far no oil or fuel leaks to be seen. However - major throttle hanging problem quickly became apparent.

When I got the bike I completely stripped the carbs, cleaned all parts in an ultrasonic cleaner, and carefully checked all jets etc for blockages. I have re-set the needle heights recently (2nd notch from the top/blunt end); carefully bench synched the carbs. Inlet rubbers are new, manifold rubbers are new. Original air cleaner box/plenum is fitted with a new air filter. Throttle cables are new and I have checked that there is not tension in the throttle cables when throttle is 'off'. Mixture screws are 1 turn out on all carbs.

Is there a routine to follow for diagnosing hanging throttle somebody can point me at please?

Thanks, Mike

This thread is worth a read Mike, a subject that crops up regularly.
Nigel started the subject with a view to gathering together thoughts on the subject, lacks Ken's input as he was not able to contribute at that time.

This was what stalled my project Mike, as yet I've not got to the bottom of it, partly due to winter but also my mum became very unwell.  Sadly she passed away on Wednesday.

Sad to hear about your mum, knowing what it feels like too only further ago. Try and think of all the good memories and times, but appreciate it's difficult initially to do so.

Thanks, I would have loved to have had one last summer with her but it wasn't to be, her chemo just wasn't working

[McCabe-Thiele (Ted)]

Sorry to hear about your Mum Dom.

[Oddjob]

From the bottom of my heart Dom I am truly sorry to hear that, my mum passed 18 years ago and it’s still an open wound.

Mike, I’ll post something in a day or so out of respect to Dom if that’s ok.

[DomP]

Thanks Ted and Ken.

Don't worry about posting Ken, I need to get that project up and running again

[DomP]

This forum really is the friendliest place I've ever known

Dom, sorry for your loss, that is a tough one! 😥

Mike on a cheery note, I like the fact that “nothing fell off” is like a win! (thought it was only me) 😂😂

My thoughts are with you Dom. I know it's really tough to deal with. Best wishes.
