Hi there, I'm new to the forum and I recently purchased a new to me 2005 Bonneville Black. The bike has 5,500 miles on it and I mostly ride it around town for commuting in Boise, ID. When I received the bike in early June, there was some gas in it and I topped the sucker off. It made it to about 120 miles until it had to be switched to reserve. On the next tank of gas, the bike began sputtering at 99-100 miles before switching to reserve. On my most recent tank of gas (fill up #3) it sputtered at 109 miles before I switched to reserve. Between the 1st and 2nd tank of gas I changed the spark plugs, oil & filter, and adjusted/cleaned/lubed the chain. I found it to be interesting that the mileage seemed to go down significantly. Since I'm new to riding the bike, thought I would ask if this sounds like a normal fuel mileage range? Should I be worried about the drop from 120 mi to 100 and 109 mi before reserve?

Other than switching the oil filter and plugs, the bike is completely stock.
