Hello, I posted this in the Sportster forum a few minutes ago but was unsure if it was the correct forum to do so for my topic. So im going to repost it here. So here you go, any help would be appreciated. Thank you.


Hi, I recently purchased a 1987 883 (punched to a 1200) which ran like crap so I had the carburator redone at a reputable local shop. After installing the carburator I discovered it didnt run any differently, it sputters during acceleration from a quarter throttle to a 3/4 throttle, do you think this is just carb related or could it be electrical?
