Here you go, my husband put a bunch of model #s on this thread.

After all that hoopla, if it fits, it runs, then it works;) also check the hose is clamped properly.

BMW ST800 Cutting Out Solved!
 

Dear Friends,

My ST800 always cut out after a long blast on a motorway.
This afternoon I poured half a bottle of Red-Ex in the tank and went for a long ride with a long fast ride on the M11.
After coming off the motorway the bike didn't cut out no matter how much I tried by riding extremely slowly and speeding up, slowing down, speeding up.
It even runs sweeter after the dose of Red-Ex.

Regards,
DaveTee
