Missfire troubles
I have a 2009 1200 Nightster that I purchased recently...The bike has 7,500 miles and within the few last week's I noticed a few missfires. Rarely happens but I want to fix the problem before it turns into something worse later. Happens in the first minutes of riding, I had it happen at idle and had it happen in 1st gear with low throttle. For a split second it just stumbles and picks up right away...Anyone know what to look at?
