I am trying to change spark plugs for my 929...i cant get the tank off, cuz there are 2 big hoses seem like cant be disconnected. and how to shut up the gas? gas were leaking when i disconnected one of the hose. any help? thanks

 

Best bet is to get some wire and tie the tank off to your helmet holder on the rear. Don't disconnect anything. You have plenty of room getting under there to take off airbox, etc. Just take off front bolts holding tank and then the rear one under the seat and prop it up. I found that this is very simple when changing plugs. No gas spillage too!
