Idle

[angus]

Have had bike lying up for a while.Started her up and is idling to low less than 1000rpm(I have to turn idle screw up to get it to tick over).After driving for a while 30-40 mins when I let it idle and it idles at about 3500 rpm and I need to adjust the idle screw again and its fine.Any ideas.Conan

About how long was it "lying up"- did you stabilize fuel? Was your idle normal before? Might be running on 3 cylinders till it warms up.

lying up about 5 months,had the carbs off to replace intake manifold boots(leaking).New plugs,caps,air filter,oil and filter.All 4 downpipes are hot(all feel the same temprature.Conan

Sounds like you still might have an air leak.
Maybe one the boots got pinched when you replaced them? Did you change the manifold o-rings as well?
I would try spraying something like wd-40 in various spots around the carb connections and listen for rev changes.
