I'm starting a new thread here hoping someone can talk about what their intake manifolds look like when the carbs are pulled after running.
Mine are wet with gasoline. As if the carbs are just dumping the gas into the engine. and then when I lift and tilt the carbs back, gas pours out the airbox drain (this might have occurred when I turned them on side to remove the throttle cable but I think it happened when I just pulled the airbox drain hose with the carb set still pretty level..
Anyway, I've been battling a high idle issue on this bike I bought not running. Not to go through all my carb cleaning, trouble shooting, and results, but in short, this is a California bike with the pair system removed and T lines off the carb bottoms plugged (used to go to the evap canister). When I run it with the chokes closed, and idle screw all the way down, I get this 3000 rpm idle. and yes, carbs cleaned, pilots cleaned, orifice to pilots clear, pilot/mix ckt clean, mix screws 2.5 turns out, stock airbox, exhaust, jetting, carbs bench synced then mercury manometer synced... I've been doing my testing with fuel delivered via two funnels and extensions to the carb fuel lines..
I'm getting the feeling that there is some sort of vacuum pulling the fuel up from the bowls into the throat but that don't make sense either.
so does everyone's intake manifolds get a puddle of gas at the bottom from idle (or high idle>?)
