I love my Pioneer 500! This thing is awesome and it will do it all. However, I have a question and some concerns. First, My pioneer when new and out of the box so to speak, shifted really rough with a loud clunk and a jerk with each shift. Now, after about 90 miles, it shifts smoother but it seems to slip slightly going into gear when shifting up as if a clutch is slipping or something before it grabs. I am wondering if anyone else has experienced this type of thing. The salesman said the shifting is supposed to get smoother as it breaks in but I am concerned something has been damaged. Also, would downshifting under throttle causing a rev and then it not shifting into gear damage anything?
