Hi guys, need to find a quick fix as I'm booked on the Santander ferry on Monday. My 2005 75k 1200 GS has been very mechanically noisy on idle ( NB. Valves and end float are in spec. ) for a while and I was expecting a throttle balance to sort it so just had it done.
When I collected the bike it was started from cold and sounded spot on. By the time I got home and the bike was properly warm it was back to a bag of spanners. Whipped out the plugs and the right hand pair looked fine but the left pair where black and sooty, they where due a change so replaced all with new ones and went out for a ride but no change to noisy idle when warm. Got back and let it idle on the drive and disconnected the left hand stick coils and it still ran on right pot only, tried it the other way round and and it cut out. So something defo not right with left pot.
BTW, it seems to ride fine and pulls well through the rest of the rev range and it has Nightrider AF-XiED units fitted. I have had a quick search and usual suspects seem to be TPS, Idle Control(is this a different term for the stepper motors) and Lambda sensors.
Is there anything else I should be checking?
I'm aware that you can get a non BMW TPS units at a better price, is this the same for the other units ? If so can you point in the right direction, please.
Need to try and source the bits tomorrow.
TIA.
