Speed Four Fuel Consumption Oddity

[-Monty-]

This seems to have already resolved itself but thought I would ask on here anyway to see if anyone else had encountered a similar problem.

I've had my Speed Four for a few weeks now and fuel consumption seems to have been pretty reasonable. Whilst out on the bike the other day, the fuel light came on after just 50 miles of riding since the last fill up (brimmed tank). This equates to around 18 MPG with pretty sedate riding. I filled up and rode another 50 miles (roughly) and consumption seems to have gone back to normal. Just to note, I didn't notice the bike running oddly whilst it was returning 18MPG so am a little confused as to what happened.

Any thoughts appreciated

PS: I am 99% sure that I didn't just reset the clock at the wrong time.

Not the usual place I go to but I have filled my CB500 there before and not had any problems.

Did the tank need a full fill up? i.e. Is the fuel light fckn with you?
Only time my Speed Triple used a lot of fuel was when the plastic tank connectors leaked. It was accompanied by a strong smell of petrol in the garage each morning, and didn't correct itself. Needed new tank connectors.

Do you think someone could have stolen petrol from the tank? Has it been parked up anywhere?

I would think even on a trackday you would get more than 18mpg.

Nah, wouldn't be that. The bike is kept in the garage in our back garden. If someone had gone to the effort of going over the fence and then breaking into the garage then they probably would have stolen the bike rather than just some fuel.
