Is it any different if you have a boost bottle and you are sync. your carbs. *Does the boost bootle have to come off or what. *I know the procedure for sync. carbs with out boost bottles. *Just let me know.

Looks like a good question no one seems to know. *If any of you do find out let me know. *Because carb sync. measures vacuum from each side of the engine and balancing them to make sure you get the same fuel and air in each cylinder and a boost bootle helps equalize them so what do you think.

no it doesn't have to come off. you can set your carbs with it on. the boost bottle is basically for your reeds. thats what i was told by a dealer.

You do not have to remove the BB to sync the carbs.

Thats what I have been doing. *Thanks for the help just wanted to double check.
