Hey guys, I have a 400ex and I was wondering the best way to make my bike have more power for free. I know this may sound extremely stupid, but I'd like to know because I wont be able to buy anything until Christmas time. Another quick question, In order to adjust the valves, do I have to cut the old plastic rivets off and replace them with new ones? I know they are cheap but I was gonna do it tonight and none of the dealers are open today.
