As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

Hey all - I have a bandit 1200 powered 1100l bike. I got it running today but when I give it gas it stalls. I suspect vaccuum leaks and that im running lean. Can anyone advise the vaccuum ports that should be blocked and any other ideas that could help? Im running 150 mains, 32.5 pilots, pods and high flow exhaust.

Thanks
 
I don't know the motor but those carbs have a sync port on each diaphragm cover. Cap off any ones you're not using. I use the #2 carb port for my petcock and cap the rest.
I run 140's & 35's. Siamese K&N pods and a Kerker

What about the one on the outside of carb 4? When I cap it the motor stalls. Is this some kind of breather?
 

Leave it alone. From the casting it looks to be a bowl vent.

Put a Dale Walker Holeshot Preformance jet kit it is the only kit I would ever use for a Bandit motor. The DJ kit just plan suxs plus you can call Dale and he will personally help you if you have any problems.

Thays not my picture, but they look identical to my 1989 gsxr 750 bst36ss'
 
I had oil on plug 4, plug 1 looked good. Didnt check 2 or 3. Im going to retorque the head because im sure that oil is fouling plugs. Also, the motor is turning over super fast, like low compression. I dont think its piston rings, because I compression tested it when I bought it.
 
Did you measure you carbs? If not pop them off and measure them

there is also a number on the side that will match the numbers in the manual and you can track down exactly what bike and country they are from.
