I hate to be the bearer of possible bad news, BUT. I am pretty sure that the newer Honda Centrifical Clutches are alot the same. MY 2003 250EX did the same thing. I work on all of my own toys, However this one is waranteed so why do it myself?? I took it in to the shop they adjusted it for me. It ended up being a broken spring in my clutch. They had to take it apart and replace, basically the whole clutch. If it was not for my warranty, I would have been out big cash.
