rev counter diagnosis

Hi guys
Can anyone help.Took the cat out for a ride today,went well until i stopped for a pit stop.Bike then refused to start,we bumped it and it ran fine but the rev counter kept going from 0 to 8 then down to 3 then 0. It just kept repeating these codes. It now won't start. I know its trying to tell me something but I can't find a list of codes. I've looked in the Haynes manual but unless I'm missing something I can't find any.

any ideas Dave

Alright Dave

You got an owners manual cos it's in there.

One is definitely fuel sensor related. You had the tank off recently and didn't plug the wires back together or just not quite enough, and the other I think is something to do with the throttle??

yeah i've just found some info on another site.something that calls itself tps. but why is it not starting. once i bumped it it ran fine.

Tps is the throttle position sensor ( the 3,000rpm fault)

If this is faulty the ecu could be altering the ignition to suit the fueling it's expecting. Try starting with a light twist and see if that helps.

The 8,000 rpm is saying that there's an issue with the reserve light on the fuel tank

Sorry if I'm telling folk how to suck eggs

Hi Guys

Thanks for your posts.It turned out to be electrical.I cleaned all the connections on the earth side and that seems to have sorted it.
I knew it was not fuel since I took the tank off just before last summer,gave her a service, and we spent a great summer terrorising the good people of Wales she never missed a beat.

Alright, if the revs aren't dropping back as well and you've balanced them you might need to adjust the pilot screw/mix screw.

I've just been though the same today with the missus Ninja, adjusted the mix screws and it's bang on now.
