OK,, You were right,, I have never had the tank off, so I pulled the tank, and that little hose was squashed flat between the tank and mount on the frame, So i squished it back out, blew and sucked through it a few times,,(hmm,, the air flows now) put it back together and took it for a ride around the block,, I could not belive the differance,, started right up without the choke, idles smoother, and a gain in acceleration,, all these things from one little breather hose squashed (im doing my own work from now on, I think the only time the tank has been off was when the dealer installed the tachometer)
