Hi,

I have a little problem with my xt660x. The trafic was busy, and i was driving slow. When i was shifting down to thirt gear the engine stalled a couple of times when i used the clutch.
Normally when i start the cold XTX the throttle is more smooth than when the engine is at his normal temperature.

Recently i changed the stock exhaust with a Leovince X3 exhaust, can this be the reason?

I think the problem is the idlle speed. What do you guys think?
