Hi Gabe,
Masking an idle problem by increasing the revs, is a good way to forget you have a problem. I don't remember, did you do Martin's air/fuel ratio test, warm, 1000rpm, press starter?
I was surprised when I did the maths on what was my typical ride (regarding idle/total ride time ratio) Half hour start to stop, two minute warm up, four, one minute traffic stops. I would have guessed that at one percent, but it's twenty.
Hi Dave,
Yeah, I know.... Sticking my head in sand won't make the problems go away :D
So just to recap, where we are now - idle is high - 1100-1200RPM, and I can not get it any lower, I have tried today, I am at the end of the adjustment. Whenever I am lower, the engine is cold and maybe that makes it stuttery
Bike needs choke, whenever colder than piping hot - e.g. driving for 15 miles in 20C I can restart it immediately without the need of choke. If left for 15-20 minutes, some choke is needed, otherwise bike stumbles or it is hardish to start
Rear disc is getting hot even without using the rear brake. In comparison the dual discs up front will not get as hot even though they have been used properly. By hot I mean hot as to be able to hold the rotor, so I'd guess 50-60C. The wobbly disc, I have showed in the videos were replaced by a straight one bought of a member of a local BMW club, no change, even though the rear wheel rotates a lot more freely. FD, DS I did not touch as of yet, so they are the same old ones.
I have not checked the plugs after a short ride as Gryph suggested, will do that next, as they are the same perfect colour after a day's ride.
The Martin / Lentini method does nothing to my idle, pressing the starter button, whilst bike is running makes no difference.
I checked again today, I have NO detectable air leaks anywhere. Spark plugs - correct range, correct gap, valve clearances correct, TB's synced, TPS set. People driving the same type of a bike in similar circumstances report some 20-30% lower consumption.
Maybe I need to
a) stop obsessing and drive the bloody thing (driving it is not a problem, not obsessing, well that's another story)
b) take the bike for a proper CO, fuel pressure, etc analysis and stop obsessing.
c) do nothing to the bike but visit a psychologist, who could help with my OCD :)
