Have a 98 and changed tanks. Tank has a breather tube but the gas cap makes a whistling sound after a ride. I put the 98 cap on the tank that I think is from the late 80' or early 90's. Normal?

Blow out that hose from the cap opening with your compressed air and disassemble and clean your cap.
It can. It creates a back pressure in the tank that doesn't allow fuel to flow through the petcock into the carbs. If it's just enough to slow down the fuel flow, that would account for hesitation at that speed.Would it cause hesitation at 60 mph? The bike is losing power at that speed.
Heh, I removed that diaphragm too. Cut a piece of lawn mower filter and stuck in there just to make sure nothing could get it but it breathes perfectly now.mine did that until I ruined the rubber diaphragm in the cap and removed it....now it works fine without the whistle.
