a lot of spit back from carbs ,, got that almost fixed .
? ? ? question the vacuum line on the #2 carb goes to some type of mechanical timing advance ,, if I pull the line off the carb side and SUCK on the line ? should I be able to suck air through the tube ? or would / should it be plugged and NO AIR is pulled through the tube ??
I have owned it from day 1 1991 and it does have a vacuum advance under the faring ,,,, I just do not know if it is working correctly .
Thanks Speedy Gramps
It should seem plugged. It help flash off fuel when you chop the throttle to meet emissions standards. No performance gain with it.
