2012 DL1000 Airbox Backfire
I picked up a new to me 2012 DL1000 yesterday with just under 5000 miles on it. I've rode about 80 miles on the bike since yesterday and have noticed that occasionally there seems to be an airbox backfire of little "pffft", for lack of better words, along with a brief loss of power while increasing throttle after decelerating through 3,000 rpm in 1st, 2nd, and 3rd gear. Other than that the bike runs like a top and pulls hard. Now, the previous owner said he hasn't been able to ride it much the past couple of seasons and that it has been sitting for a while. There was barely any gas in the tank when I picked it up, but could this be caused by bad fuel or other fluids? Or is it something more serious to worry about?
