it is not all that difficult a job to tear down the motor. I would strongly recommend getting the Hayes manual and read thru it. also Dinqua's web site is very good on the tear down. On the reassemble I would make a few changes his cam chain guide procedure (but minor stuff)but it will get you thru the whole thing (make sure to have beers as indicated).
Take your time, be organized, label everything, if it is going to be apart for a long time, take pictures and make notes so you don't forget what you were doing.
the ratnet has a number of well documented motor threads, some very good 'what not to do' examples there, all good reads.
