Ok, so hello everyone, I'm Nikko. I am new to the forums here, and to Harleys. I recently bought a 2006 Sportster Custom XL1200C, it only had 7800 miles on it when I bought it. Up until this morning, I had no issues aside from the primary chain being a little loose. I took it back to the shop for that and they tightened it up for me. However, just this morning, while on my way to work, My speedometer and odometer stopped working. The light is still on, and everything still works, except for the speed/mileage. The blinkers still self cancel and all. THEN, after about a mile without the speedo, all of a sudden the check engine light comes on. Does anybody have any idea what could cause this? pictures, or diagrams would be a big help, as I still don't know my way around a bike too well, But I am somewhat mechanically inclined. Thanks in advance guys.
