hi guys i have an air leak on my intake mainfolds/boots on my 1990 cbr600.
when i start the bike it runs ok for a couple of mins but the the idle gradually increases, i have tried spraying some started fluid around the boots and this brings the idling back down for a few secs. the carb is pushed all the way into the boots and the screws are as tight as they will go, is there any type of glue or sealant i can use on them?

 

Just replace them and be done with it. They're about $9 each.
