Hey guys, Even with a fresh air filter, my CBR is really a thirsty little pony. My last fuel-up 20 minutes ago calculated out to 8.3l/100km. Now that's by far my worst, but I've had a lot in the mid-high 7 range. These tanks are pretty much all city riding with lots of stop and go, and I'm a big guy, but I'm still concerned. I've got new spark plugs waiting to go in, is there a chance they might help with this? I don't know with any certainty that the bike NEEDS them, but after seeing the state of the air filter I'm not going to hazard a guess on how long it's been since the previous owner did them. Any other suggestions on what I should check? EDIT: One other thing that occurred to me… I'm having the cam chain tensioner replaced tomorrow, and because the noise is so damned annoying I haven't really revved the bike much above 4000-5000rpm when it's warmed up, so maybe I'm opening the throttle a lot more in lower gears for longer times to get the speeds I want? Sorta thinking out loud I guess, but not sure what the effect of higher throttle at lower revs is like compared to.
