Hi there, everyone.

I'm just doing some info gathering, so I know where to look first etc etc...

My '98 R1100GS is getting roughly 11km per litre of fuel (Which is about 9l/100km).

I notice when I start in the morning, it does smell very rich (I can smell the petrol).

I don't have the tools to balance the throttle bodies, so I can't check that.

Beyond that... what could really cause the mileage to be so poor?
