This bike has a rather serious problem when cold. The front brakes apply themselves and the engine reduces its power. It seems to shut off two cylinders and the brake lever goes hard as a rock.
If I apply a 8mm spanner to the rh bleed nipple to release the fluid pressure all becomes well.
This usually happens just once within 5km of starting out, but sometimes she does it again after abt 20km, then we are OK for the rest of the day.
While warming up with the choke on the ignition timing seems to wander all over the place. Cylinders come and go, and sometimes that brake lever locks on before taking off.
Lights behave normally. The amber warning lights correctly extinguish after 2sec and the red lights extinguish after moving off.
I have cleaned the TCS unit connectors and checked and cleaned the fuses.
The TCS OFF switch has no effect on this behaviour, or anything else, for that matter.
The TCS unit has a PCB that has been "potted" in clear epoxy. I can't see any burning or other mischief there.
Anyone had this type of insanity before??
