Picking up 08 KX100 for my kid this week. 1. Any major issues with this bike I need to know about? 2. I would like to change is clutch perch. Can you recommend any in-expensive on the fly clutch perch? 3. Also the plastic is just ugly, the shape etc., any recommendations as well? We will probably only keep this bike for this summer then move up to full size bike. Thanks tony.
