I recently got a 2006 CR125R, and I absolutely love the thing. problem is, when I start to accelerate and move into higher gears on the street the engine seems to "pump" for a moment, and then it'll return to being smooth as ice. it does this a lot, and I'm not sure what to do. I'm new to 2 strokes, so I don't know much. the bike only has 6 hours on the top end. any advice would be appreciated, thanks!
