hey i got a 300ex a couple months ago and i was over at my friends ridding.
his dad said i needed a valve adjustment since it sounded like a wind up toy.
i don't really want to tinker with it myself, since i dont want to screw anything up(unless it is easy enough-if so could anyone tell me how), so im wondering how mutch would bringing it into a honda shop cost(estamite), and if it hurts ridding a lot with the valves off.
