I don't lose power when it happens, it always seems to happen on an incline for some reason but this might be unrelated. When it happens, I play with the petcock and it seems to bring it back to life but once again, not sure if it's related. It happens when I accelerate.
Please let me know if you have any idea on what it might be, thank you.
First, your idea of a vacuum isn't right. You don't have to do anything when you install the tank. The vacuum that we all refer to is the sucking power of the engine as it's working. The internal pumping of the piston creates a vacuum, drawing fuel and air into itself so it can compress it, blow it up, spin the crank, turning the front spocket and making you go down the road

Tell me this, when you get on the the throttle and really accelerate on flat ground, do you have the same problem with the engine cutting out?

Sounds to me like it's a fuel flow issue - probably a float height issue. The bike is starving for fuel on an incline because the float is too low.

Take the handle of a screw driver and whack the float bowl a couple of times. If this helps, then you need to run some carb cleaner through your tank... Come to think of it, do that anyway
