OK, so here's what I found out.
Firstly, the fuel levels appear to be spot on.
Cyl 1 is getting a spark.
I tried running the bike with the sparkplug removed, first from Cyl 2 and then from Cyl 1. With the Cyl 2 plug removed the problem persists. This seems to rule out a leaking inlet valve in Cyl 2 since the pressure in the cylinder is able to excape through the sparkplug hole.
With the plug removed from cyl 1 something very interesting happened. The problem persisted, but also exhaust fumes were escaping from the sparkplug hole. I'm guessing that this means that there's a leak between cylinders 2 and 1? Possibly a failed head gasket.
Thoughts?
