Hi All! First post! Could anyone tell me where the pipe (pictured) goes? It's the top one by the water pump. I have checked a workshop manual but there is no mention of it. Also... I got the bike with an aftermarket carb (pictured), it seems to be an unbranded one but similar to a stage 6 one. Has anyone got any information or a manual for one of these? I am tempted to swap it back to stand but the bike did run well on a test ride with this carb, but it has lots of ports with nothing attached. Thanks!
vacuum - fuel - oil nipples on the carb. the crankcase pipe could be a vacuum line to presurize the fuel pump allowing it to pump fuel to carb, it could also be a breather, im not to intouch with the aerox motors, but i am sure one of the guys will pop in and cover that area for you
