Hi martinc, im about to sync my carbs on my 2000 r1. You stated in a thread to hook the hoses in the holes below the carbs. Are the holes located in the manafold and plugged with allen head bolts? I asume if so i need to screw in some sort of fitting for the hose to attatch to. Is this correct. One more thing. Do i leave the hoses that are linking 1 and 2 and 3and4 hooked up during the syncing.thanks for your help.
