LukeXF Posted January 22, 2019 Share Posted January 22, 2019 Bike has been not used in 8 months (I’ve been away). Kept in a dry underground Carpark.Turning on the ignition about 2 months ago wouldn’t work. Recently I’ve been on a mission to fix it.Here’s where I’m at; I’ve replaced the battery with a brand new Halfords one. Taken our the spark plug and tested it - it has a good spark it turn over fine, but doesn’t start Tried bump starting it in 2nd but nothing Turning on the key, the engine light comes and pump primes (the sound) for a second or so, then they light goes off indicators, brakes and the front light are all functional when the key is turned on there’s 3/4th fuel in the tank, the petrol smells like... petrol YBR 125 2010 model. Full service history up until this year. Any suggestions? I think it might be a fuel problem now. Next attempt is to look at the fuel injector.

rennie Posted January 23, 2019 Share Posted January 23, 2019 YBR's are difficult to start!Has it got a choke To start Sue's (06) full choke, no throttle, use kick start if battery flat.once it starts do not even breathe on the throttle for ages, then turn choke down slowly,then try revving it.All bikes are different though! yours might be completely different!

Next attempt is to look at the fuel injector.To check the ECU is earthing undo the electrical connector to the injector connect a test light between the two wire on the harness side, crank the engine and see if the lamp flashes ( if you have a noid lamp do it with that) Quote Link to comment Share on other sites More sharing options...
Old-codger Posted January 23, 2019 Share Posted January 23, 2019 If you have a decent battery and spark I would drain all the petrol out and put half a gallon of fresh petrol in. If your bike has a carb drain the float bowl to. Petrol goes off after a month or to, once you are up and running mix the old petrol with the new stuff to use it up.
