After firing bike the other day and having it just fall apart at about 3000rpms i checked battery cables (last year ground was loose and that fixed it, but my clock was also resetting). So i decided since the bike has 8000 miles to just go ahead and replace plugs. After all the work getting plugs out i did wires too. Wow. What a difference. Id swear i picked up 10 hp! After all the posts on plug replacement i was a little concerned but after getting it done. it was a whole lot easier than my v8 s10!
