hey guys it me again i have a 94 f2 and i am a little worried that my bike is not as healthy as it should be... when i downshift i hear a pop...pop...pop in rapid succession coming from the exahust, also i have trouble starting it cold and it sounds like the starter motor is fine and i just replaced the battery. I also think it is a little jerk sometimes when cruising at high speeds. I seem to remember someone telling me it could be something to do with the fuel system so i was wondering what can a rookie do... because i dont have the dough to take it to the shop again, I just had my carbs synched and it sounds like they are coming out of synch again, i read something about what causes that but i didnt really understand how to fix it... thanks any advice would be appreciated.
