hose on intake manifold

[goldwingrider]

ok all that must make sense. the bike was back firing when I would shut the throttle down. I changed the hose out and couldn't find any hose that was not connected so I put a screw at the end of the T connector. No more back firing. I was wondering if anyone else had this problem and what did they do about it? I am going to keep an eye on this part of the bike to see if I start having any problems. .
