I am having an accelleration problem. warmed up choke off it idles fine,turn the throttle and it acts like it has a rev limiter. ride it around with the choke on for fifteen or twenty minutes backfiring and bucking and it will start running fine when it gets hot.let it cool down and start the same process over
things checked,timing,coils,carbs,plugs fuel lines and vac lines.no visible wire damage to ignition.hope i covered everything. any ideas would be appreciated

Welcome to KF.
First thought was a bad carb cleaning, float adjustment or a lack of a carb synchronization. Especially since you have ohmed out your coils, plugs, wires, etc. Keep us up to date.

 

+1 on the carb cleaning. If you havn't done it yet, grab a manual and give it a good cleaning
