hey guys i have a 98 cbr 600 f3 i have been rebuilding it after it has been wrecked by the previous owner got it running but after a month it starting stuttering really bad under load at first i thought it was the clutch so i replaced that didnt fix the problem then went to the fuel pump still no fix then i moved to the carbs last and cleaned and re jetted them and synced and now the bike wont start in need oh some advice on what i should do i dont want to get rid of the bike because its a great bike when it running but if i cant fix it i might just do a f4i swap on it and just call it quits
