prime is definitely not for running the bike but priming the carbs, like if you have had them iff for a good cleaning 😅

Wow, that's what my bike sounds like. I just got my first street bike, a Bandit 600s, and it is almost un-rideable. I assume that pri is a primer function. I'll try leaving it open for a few seconds. Thanks for the video.

No, the final solution is to buy a cheap manual fuel tap and replace your crappy old vacuum tap, then block off your carb vacuum port. That will fix both the vacuum leak and whatever fuel leak you have going on in the tap. Even if you block off your vacuum ports on the fuel tap and intake manifold, you'll still have a fuel leak from the tap. The prime function is not designed to be used for daily running so you won't be able to access all of your fuel if you run low. The other option is to buy a shitty petcock/tap rebuild kit on EBay and fix your old tap, then it will need to be fixed again in some time, so the best way is to do what i say and switch to a manual fuel tap like you'd have on a little 125cc. That's the only permanent fix

Replace petcock with one you can turn on and off, original petcock sucks and will flood your whole engine with gas.

@@lewisfirth6502 My motorbike's been off the road for 8 months. I started it. When I started it, the fuel valve was Pri. The engine barely started. After a while, it continues to run unstable in neutral gear at a thousand revolutions and sometimes stalls, but it is still driven. Then I start riding it. There is no problem around 3 4 thousand revolutions, the engine flows, but when the engine slows down in 1st gear, it stalls directly. I start it again with choke and then it stalls again. I can't find what the problem is. Also In 1 st gear throttle is so unstable. Sometimes I just touch throttle very softly and then the motorbike rushes forward fastly.

1. test the vacuum pet cock . you can do that with a small hose and vacuum pump. with 1 hg the fuel should flow. if it does not flow remove the 2 screws that fasten the pet cock. check for clogged strainers.
