Accidentally left on PRIME

[Guest]

I've accidentally left both my bikes on "Prime" on the sidestand and yes they leaked.
I have since left one of my bikes on "Prime" again but this time no leak, the only difference I can think of was it was on the centerstand.
So, I'm thinking the level of fuel in float bowl being at an angle while bike on sidestand might not allow enough height to completely shut off the fuel resulting in a leak.

I'd like to update this, yesterday I left my 1000 on prime for a couple of hours, it was on the centerstand, and it did leak. So, with the two bikes I have one leaks on the centerstand and the other one doesn't. Oh well, so all that mumbo jumbo about the float bowl being at an angle is probably just mumbo jumbo.

On gthe leaky one..raise the float heights 1/2MM and see if it stops.

Sticking float/needle valve or wrong float height surely has to be the problem I would think how else can the fuel rise to the overflow? I ran a gs850 for two years with the vac pipe to the petlock blanked off. So on was off and every other position was on never had a fuel leak.

reserve relies on vacuum as well so the only position that would work without a vacuum line would be prime. the other 2 would be "off"
