Someone may of buggered up the rim sealing surface while prying on a tire, my Daytona has a rim that has a tire tool ding that doesn't like to seal.
I tried to ride my RZ to church Wednesday night. It didn't want to go cause by habit I'd turned the fuel cock to prime thinking I was turning it off. The fuel to air ratio was too much as the float valves seeped a little flooding the engine. When I expect not to be riding my twins I usually pull the fuel lines and plug them with a dowel pin. Then I run the engine a bit to open the float valves so they don't think stick to their seats. I fought a house fire once that was caused by a riding lawn mower's float valve that leaked about a gallon of gas onto the garage floor. The gas flumes got to an ignition source and went off. I noticed after we had knocked down the fire down that the sheet rock had the screw heads popped out. That told me there had been an explosion. I went over to the lawn mower parked there and found the concrete stained under the lawn mower. The owners lost their car in fire and garage contents. Since then I don't trust pet cocks or float valves.
OK I'm done with my safety rant for the day.
