Need some advice:

The weather has dried up and warmed up enough at times in the last few weeks to get out and ride a couple of times. That's the good news. The bad news? The last time I was out the throttle seems to stick most of the time. That is to say that when I roll on it just stays there and doesn't spring back on its own. I can roll off just fine, but it spooked me a bit the first time it happened.

Do I just need to lube somewhere?
