Just bought a used 06 ttr125, I got it cheap bc the guy said it was running bad. First test ride the throttle was VERY sticky, had to open and close it by hand, it was jerky and hard to control. Took the throttle tube off the bar and there was sticky residue everywhere, clean it up and put some gun oil on it. For good measure I changed the oil, cleaned the air filter, and cleaned the carb and jets. Rode it again and it was MUCH better, the throttle feels nice and snappy in my hand. but while actually riding it's still just a little sticky and sort of tricky to control. What else should I try? The cable looks ok as far as I can tell.
