The 1st thing that I would do is check the Cold Cranking Compression, with the throttle Wide Open!
Regardless of when the valve tappets were last checked!
Many 2008-2009 units had an over-active KACR. A KLR650 does not start well in a cold climate with less than 80 psi of CCC!
Fresh gasoline starts better than old gasoline. Winter Blend gasoline starts better than Summer blend gasoline in cold conditions.
A 100% clean carb is required, whether the CCC is 80psi or 125 psi. Paying particular attention to the 3 little pilot outlet holes at the Bottom Edge of the throttle plate.
Remove the Phillips screw from the throttle cable bracket before dis-engaging the throttle cables from the carb, remove bracket with cables!
Remove the carburetor air duct clamps Completely.
Push the rear air duct off of the carb with your Left thumb & spiral the carb out of the engine bay with a counter-clockwise rotation. Installation is exactly reversed.
Modify at "YOUR OWN RISK"!
Still riding my 1987 KL650-A1. 85,000+ miles & counting
