Wont exceed 4,500 rpm then stalls and wont restart - on route to MOT

<< < (4/13) > >>

I stripped the carbs, found a blocked main on number 2, a blocked pilot on number 4 and float heights a bit out. Also fitted a fuel filter, checked the timing with a strobe and fitted a working oil pressure switch.
It ran like crap at first then sorted itself out and was fine for an hour but lost all power just as I was arriving home - This was after sitting in a traffic queue for some time.

SteveD CB500K0:
The loss of power may have been caused by overheating (happened on my 550K3 many years ago queuing to get into Silverstone).

Keep an eye on the fuel filter - I don't like them and believe that Honda would have fitted one if it was really needed. My K2 had those little in-line filters (two) but they got clogged easily and then the engine stopped.
(Maybe you will say that that crap would have gone into the carbs and the engine would have stopped anyway...)

I'm hoping that's all it was, the queue was quite long, I'll see what it's like when I next ride it.

The filters easier to clean than the carbs :-)

UK Pete:
This seems to be a very annoying time consuming problem for you, i do hope you get it fixed soon as these problems can really put you off a bike, i had four months where i could not solve a problem with one of my kawasaki's it turned out to be an intermittent problem with the electronic ignition, it drove me round the bend, and i ended up hating the bike for quite a while

My patience is starting to wear a bit thin with it.
Once it's sorted it's going to take me a while to build up enough confidence in it to go any distance which is a shame as this was supposed to be my distance bike with the monkeybike staying in use for local rides.
