I need some insight as to what is going on with the acceleration. I punch the throttle and whah-la nothing, can't get it to 4000 rpm. I've seen here is some topics that it could be the slides, the vacuum, the fuel filter, etc. Is this the reason that some just give up and go with the single gas guzzling carb conversion? This 83 Aspen came to me with the engine pickled and the carbs full of crap. I rebuilt the carbs with a set I purchased online, don't remember which one and got the bike to run. The acceleration is really nonexistent and disappointing after all the work put into it. Can I get a rundown of the main reasons that this happens? Is there supposed to have a vent on the gas tank? I went to put gas and there was a strong vacuum when I removed the gas cap. Just thinking that I'm missing some kind of venting and it was that simple. Otherwise the bike runs fine and wow what a smooth ride, love it. I adjusted the valves and synchronized the carbs a couple of times just to make sure. What's with this timing advance and vacuum thing? Can someone give me the scoop of how to test and eliminate the various possible situations that screws up the acceleration?
