I have a 2001 Honda XR80R. It's a nice little bike, but gas comes out of the overflow tube pretty bad and when you pull on the gas it sticks bad. Also when I'm going down a hill and i pull on the clutch and push on the brake it starts to rev up really bad, so out of reaction I let off the clutch and then I start to fly. I think it just needs a good carburetor clean, but I'm not sure. Any answers will be appreciated.
