i just put gas in my bike this evening. the dealer CLAIMED that they filled it before i picked it up, but i managed 98mi before my fuel light came on and not wanting to replace a 200$ fuel pump, i will not let this tank run dry. i put Shell Nitrogen Enhanced 93 octane into it and we'll see how that runs, but if the dealer did in fact put gas in, i managed a sad 36mpg. i have been doing a little bit of hot rodding here and there, but nothing insane, however, i think my bike is running super rich. the exhaust REEKS and dumps black smoke, the plugs were fouled to ****, and the bike has no backfires, yet it has a K&N intake and D&D exhaust. im guessing the people who traded the bike in did some sort of crappy engine tune before me? hopefully this is a resolvable problem cause im not going to be happy with MPGs in the 30s this summer. i bought the bike to save money and it wont be getting much better mileage than my Audi.
