Boom.... A new throttle cable is cheap insurance. I would at least pull the insert out of the cable housing and look at it. Check the throttle grip for wear as well...

Boom,
all what Tom said, plus another cheap insurance - a dual return spring. Not only that it is stronger pulling at the throttle plate linkage - it will safe your life in case one spring breaks...at spring break...hahahaha

I bought this one:

What happened to Rock would scare the shit out of me. I therefore installed the dual spring even before I did the first ride on my bike.

What they all said, but also look at the throttle linkage under the tank and see if there is anything there for it to catch on such as misrouted wires.

Shane,
That's what happened almost to me. The linkage of the secondarys hung at wide open throttle at the fuel hose (petcock to fuel pump). That was after some carb changes, and I routed the hose too close to the carb. I tested if the secondarys opens all the way and found out they did - but they didn't close....huuuh...fortunatly I found that out with the bike on jackstands and the engine off. Could have killed me if I were riding. Good idea to test everything precisely after some changes.

Another problem I saw were secondarys which stuck wide open at a customer's bike in Andy's shop. We found out that the guy installed some of these very thin rubber base gaskets which are supplied sometimes in cheap kits instead of the thicker 1/4" base gaskets. That thin gasket caused the carb to get closer to the manifold and the secondarys got caught by the aluminum rear edge of the manifold opening.

I remember a while back Adrian or some one said do not use WD 40 to lube your cable, but for the life of me I can't remember the name of the right shit to use, Somebody here will know. Steve

and it works.
