Hi all,
Since a little while I have noticed the following behaviour on my bike (2004 1150GSA twin spark):
-fuel consumption going up (used to do 480-500 kms with a tankful, 30L adv tank, now 410kms). Riding behaviour has not changed. A lot of motorways.
-when hot, the bike kind of hesitates around 4500 rpm. The hotter outside, the more noticeable. Problem only noticeable with a hot engine.
-With a cold engine, idle is smooth, with a hot engine it isn't. It's like it sometimes misses a beat.
-The engine cut out twice when making a U turn
. Never had that before.-since removing the cat, the bike sometimes backfires (unburnt fuel?). I have noticed some air leaks at the Y piece junctions (black deposit leaking).
New plugs make the bike behave a little better, allthough that doesn't last very long.
I have read a couple of threads and the symptoms seem to point at faulty coils. Which ones do I have to look after (location, pics)? Can one see from the outside it is faulty?
Cost to replace? Other suggestions?
Tnx for your help all.
Cheers
Demito
