I recently purchased a 97 600 VLX as my first bike (and I love it)! Being new to bikes I was wondering if anyone can tell me why and how to fix the sputtering issue I am having. I have changed the fuel puny, and bike runs great. The issue is right before shifting from one gear to another the bike sorta sputters. It does that through all the gears. This week was the first time I went on the freeway and had to get off at the next exit cause I couldnĀ“t get it to freeway speed because of the sputtering. HELP PLEASE!
