VK 540III won't idle

[dragerman]

my wife's 2011 VK540III will start and run but won't idle, I have to feather the throttle till it warms up then it is fine. Not sure but I am thinking of carb icing. Any thoughts???

All the old yamaha air cools ran this way. My enticer does the same thing when it is not warmed up. I usually just play with the idle screw to keep it happy but am thinking about using the wire trick my dad used to on his et340t

Wire trick????

It needs the carb cleaned...

My dad used a piece of blasting wire to hold the throttle open on the handlebar to warm the sled up at really cold temp's on a track stand just over idle.

Carb cleaning would not hurt. In my case it did not work. Might just be a piston port thing.

Does that have the Kein Butterfly carb?? Bigger pilot would help.

No it has that yeiknen (that is what I call it) 2 barrel single carb on my et. They only put it on the et410 and 340 ovations. Have not been able to find a decent breakdown on this carb yet. I always got a deer in the headlights look when talking to old dealer about it here as well.

His vk540III will have a single mikuni in it so a cleaning would help.

Btw merry Christmas all.
