I have recently bought what I thought was going to be a good condition bike from a dealer in York (the delivered and I love a considerable distance away) who asssured me the bike was in good running order. At first I thought it was me getting used to the bike but having now done less than 600 miles in 2 months I have eliminated me from the problem. Symtoms Excessive fuel consumption 18 plus litres in under 100 miles not holding tick over Cutting out on low revs approaching roundabouts and junctions Smell of fuel in exhaust gases The bike has only covered 27.5k miles which is backed up by MOT's but has had the tank quick release changed to copper pipe and jubilee clips so a previous owner has done some work. The dealing is not wanting to either repair or take the bike back.
A local mechanic to me has had a look and cleaned all the co0nnectors but the following fault are being seen Hall 1 Hall 2 Lambda Valve sensor Oxygen Sensor Ignition switch open circuit (I don't there is a problem there as it turns over when swtich is depressed) Could the above faults came from a faulty ECU or engine management system?
Your thoughts wisdom and help is greatly appreciated.
Mention of hall sensors makes it sound like your bike is an older 1100 or 1150. My first check would be to see if the battery was fully up to the job. A faulty battery can cause all sorts of spurious running issues and fault codes though the fuel consumption suggests there are a few things going on here.....
Hello there, I’d look at the ignition switch fault first. The DTC is stored in memory until cleared, i.e it’s a historical event log rather than what’s currently working. It could be open circuit intermittently while you’re riding, which could conceivably lead to the other faults. The cat’s probably not going to be in a good state if unburned fuel is going through. For reference I took it really easy on mine for the first week and my trip meter was reporting 73mpg, they’re not thirsty bikes..
