I bought a pair of Sportsters this year, a 1996 XLH883 (13k miles)and a 2002 XL883 (2300 miles). The 1996 runs circles around the 2002. The 2002 lean sneezes occacionally, and accelerates better when backing off the throttle. It is a struggle to get it to 80 MPH. I got the manual and checked the carb operation and all appears OK. It still acts like it is too lean, or the timing is retarded (late). Otherewise, it sounds & runs OK. It does have the dealer installed freeflowing exhaust and breather (Screaming Eagle). Anyone know about this problem or have any ideas what to check next?
