After spending many hours working on a 1979 XS1100 SF it was pouring gas out the bottom of the air box. Did the usual stuff like rechecking float heights. Rechecking fuel levels. Replacing needles and seats with K@L then with OEM. No luck. Consulted with Brady from Merriam Cycle and he suggested checking the air box vents. Sure enough the vents were blocked for later years. I removed the brass from the vents in the airbox and it worked perfect. I was going nuts trying to figure this one out. Runs great now.
