Hi all.
My KTM 690 2012 drive me crazy.
I was on a trip recently and suddenly it back fires at low rpm in 1st gear. It was hard to start again but after some trying it starts up again BUT! When I turn the throttle it dies immediately, I can manage to turn throttle slow, but when it hits 4000 rpm the Rev limiter sets in. No matter what, it can not go over 4000 rpm. It starts fine and idle fine.
it change spark plug and cap, change fuel filter ( all of them ) adjust valves, check injection and it is also fine.. have any one and idea of what is going on?
