winter jetting woes

[volcrano]

Looks like i should be buying a lid, chances are ill need one anyway as we ride in the creek alot. What ports do you pull off of for a sync? Ive got a vacuum sync from our 4-carb cb750 honda days...

lids are nice for riding in muddy/wet conditions.you shouldn't have to pull your airbox to see the carb slides,pulling your filter should be fine,thats all i do,you can see them.as he said,just make sure with the slightest touch of the throttle,you should see them both move at exactly the same time.the stock carbs also have little windows up in the carb body where the slide goes,you can check by adjusting them as stated,then open the throttle while looking at the windows.you'll see them turn black i think around 1/2 to 3/4.thats the little indents in the slides matching to the windows.they (carbs) should both turn black at the same time,hence showing you the slides are in the same spot on both carbs.the most accurate way to sync,is to get the vaccuum guage that fits on the back of carb body with airbox off that measures the vaccuum its pulling.you adjust both carbs to where they are pulling the same vaccuum as im sure you know from your 750 4 cyl.
