Thank you all. As a noobie to the KLR, what is the cold start cable? I assume the choke, but wanted to confirm.
Yes, the "CHOKE" cable (more accurate nomenclature, the "starting enricher" cable).
Not to be overly pedantic (I hope), but . . . a warm KLR650 on idle will DIE if the choke (starting enricher) cable is perturbed, even ever so slightly.
Handlebar risers sometimes stress choke cables, removing slack available with stock-height handlebars; then when the handlebars are moved to their extreme left and/or right positions, the cable may inadvertently pull the starting enricher from its closed position, STALLING the engine.
SOLUTION (in this case): Re-route, and/or re-adjust the choke cable routing. A simple re-arrangement of handlebar cable bracket (changing angle and/or position) may restore the needed cable slack, or . . . the cable may be more dramatically re-routed.
Summarizing: After installing handlebar risers, the choke cable may be binding at extreme directional (left and/or right) handlebar stop movement, perturbing the "choke" (starting enricher) and stalling a warm engine running at idle. Fixable by restoring slack to "choke" cable.
