so I got my 78 running but I can't get it to go faster than 40mph pretty slow and slow responsive wise. I found two issue one being a vacuum leak at one carb boot and also one of the mixture screws is broken inside. I hope this is the reason for this loss of power. What do you guys think I will be going thru the carbs again to fix that screw and vacuum leak. The good thing is the bike idles all day long and starts easy.
