Stalling
 

Hi all, i have an option to purchase an xt660r.
The only thing putting me off is! The guy told me the bike has a tendancy to stall untill the engine gets hot. It has non standard exhausts, also fitted with a kev mod.
Will it need a power commander to sort it out?

You need to ask the the seller when it last had a good service - valve clearance, plug, idle speed etc all could be causes.

Also what is the Kev mod set at?
