I moved this thread into the Honda forum, when you actually start the project, you can start a thread in the project room to document the process.
I always recommend Service Honda or Babbits online parts for good prices on O.E.M parts. As far as working on the machine, I know no one who has, nor have I. I do know that some parts may be hard to find. Although, most of these new knockoff m/c's and atvs use old Engines that are based almost entirely off of those old Honda motors, there may be some cross-compatability with parts, who knows.
Yours truly, sincerelly, love always, Josh aka The DirtDemon.
