Ok so I drove less aggressively then I normally would on this tank of gas (14 litres) and got 250kms. So what can possibly be causing such a loss of gas mileage? I'm starting to want to sell my bike because it just doesn't seem to be much of a gas saver vs. my civic anyways.
I just need some advice on what to look for and what I could possibly look into doing (as stated above, ex. valve adjustment) Anything would be great, thanks.
Edit: What would be a reasonable price to get the valves adjusted?
