ok....replaced ccts with manuals....bike winds to about 3500 rpm then acts like its out of fuel .... if i give alot more throttle it will pick up speed but lucky to hit80 mph......also if itry n keep it at a constant its kind a like morse code rata tat tat tat if that makes sense ......also tots of back fire on decil.......also fifth n sixth i gotta give it lots of fuel......also it will wind out btr with choke on,,.....any ideas?

 

have you got the vacuum pipe for the fuel tap on the correct spigot? It goes on the one at the back of the tap that points to the left of the bike, not the one that points downwards

 

Sounds like you've gotta do the CCT's again. Skipped a tooth doing the job.
