so... marbled now, can i remove the Air Actuated Valve under the seat?

i plugged both reed valve hoses to the cyl and the little vac hose on the AAV, but there is one large one going up under the tank to the airbox maybe? do i have to plug that one as well or can i just take the AAV out??

thanks!

u can eliminate all that just plug the nipple on the carb or at the end of the lil vac line .... only things the carb needs is 2 in fuel line one vac line to tank and the vent for the carbs the rest can be removed .... i used bid vac caps for my reed valves and eleminated everything else (i also ear shaved)

the hose that goes to the air box is the air inlet in that system.. since the system has been blocked that hose is no longer needed

that was quick, i love this site.

what about the large hose that goes up under the tank from the AAV? plug or leave it open? (on the AAV there are two 5/8'' hoses to the reed valves, and one larger one that goes up under the tank)

thanks!

EDITED:

gotcha! thanks a ton!!!!

Block the hose going to the surge tank, and rear carb vac port.

hrmmm....

so, marbled now. and turned the fuel mix screws out to 2.5 turns, still backfires on decel. up to 3, still like a popcorn maker. 3.25, still (in fact, perhaps more backfiring)

any ideas?

EDITED: forgot to mention that the PO had installed V+H pipes and degoated
