Is this fuel efficiency just because of E20, or is there something wrong with my bike?
Hey club! So I got my CB in March. It's at 4.2k kms now, and up until the first 2000 kms, I used to get normal fuel efficiency (37+ on highways, and ~30 in city) even when I would ride with normal aggression(letting a bit of the throttle go every now and then). But ever since the last couple of months, I have been experiencing massive drop in mileage. Now even if I ride super conservatively, constantly in 5th, I get approx 29-30 kmpl. I get less than 24 in city traffic now, which is comparable with a hybrid car. So I checked the instantaneous mileage in my odo, and whenever i give like 50-60% of throttle in 3rd gear, instant mileage drops immediately to <10. But I do not 100% believe this is just due to E20. I have also felt that the engine is a little bit unrefined and some amount of vibrations do get to the handlebars, and it heats up quite quickly as well.
Has anyone else experienced this, and what should I do?
