Hey guys, Back again for my quarterly+ "my bikes being weird". Street Triple 660. My fuel efficiency randomly decided to drop about a week ago. Previously I'd get 2 commutes (130km per commute) before a fill, generally the second commute the bike would start in the mid-200's "range" wise, which felt a bit optimistic, but I'd fill it with around 70-100 "range" remaining at the end of the 2nd commute. It's now reporting that I'll be super super close to running out of petrol 1 commute in. 140km range. Last time it did something similar, although a bit less "risky" (160km or something). Reporting way less than it previously would after the same distance. I figured it was an ECU thing that would sort itself out, but it seems to be getting worse rather than better. Still possible it's just that, but I'm really paranoid I'm going to run out of petrol proving that right/wrong. Is there anything obvious that could effect fuel efficiency quickly? I've checked: Clutch lever. It was maybe a little tight (still had slack but under recommended), loosened that up a bit. Fuel quality.. kinda.. in that I use the same petrol every time from the same station (BP Ultimate) General once over bike checking chain etc. Tyre pressure (check it every night out of paranoia, always run the same 40/34) I've heard air filter could cause fuel efficiency problems, but I feel like that would be a slow death, and it had a major service 3300km ago. Any other ideas? Thanks!
