The 5 valve motor is rock solid.
There are guys that have gone thousands of miles with no clearance problems.

As far as the process goes, my best advice for the first time is to read the manual a couple of times and go SLOW! From start to finish, with a lot of other jobs going on with the bike, it took me about 7 hours, including the trip down to the shop. The next time I do it, I can probably handle it in under 90 minutes. Make sure you have a full set of the Motion Pro feeler gauges, a bottle of assembly lube, a quality 1/4" or 3/8" torque wrench in inch-pounds, and a clean workspace. I also found a good set of universal joints for the wrench helped immensely for the tight spaces. I also did one shim and bucket at a time. The manual said to pull them all out at the same time, but I didn't want to start mixing things up, so I never had more than one shim and bucket out. Lastly, make sure you stuff something in the timing chain area so nothing drops in. Have a good extendable magnetic probe handy just in case.
The whole process seems intimidating, but once you've done it, you'll see it's a very straight forward procedure. If you get into trouble, you can always jump on the message board and we'll lend a hand. Buena Suerte ...SC
