I have a 2010 K1300GT which is running on 3 cylinders until around 2000 rpm then seems to run fine after that.
I have a seven mile run into work, and the bike must be burning fuel in the can as it is glowing red hot internally by the time I get there. Header pipes are fine and a fairly even temperature across the four.
I have had a BMW mechanic run a 20k full service and diagnostics with no fault codes, but he has been unable to source the problem
All injectors checked for resistance.
Throttle butterflies checked.
All spark plugs renewed.
No 2 cylinder plug cap was swapped for one of the others and then the adaptation values were reset.
Fitted booster plug which registers the air temp correctly and is doing its job enriching the mixture.
At a complete loss what to do next so any suggestion will be welcome.
