I would like to rebuild the motor myself. While I've never done a motor rebuild, I have serviced my own valves several times, and replaced a head gasket once. I'm confident that if I took my time and had plenty of research available, I could accomplish the task.
I'm still evaluating the cost vs benefit of rebuilding the motor myself. The benefit would be having a 0 mile motor. Then again, it might be worth spending the money to just by a motor off of fleebay, throw it into the bike over the weekend and be done with worrying about it.
So in order for it to be worth rebuilding, I need to really know what I'm getting into. Aside from gaskets, what really needs to be done to the motor?
-Rehone the cylinders??? Is this possible, or must the cylinders be bored over??
-Crank bearings and rod bearings??? Should they automatically be replaced, or should they be examined and replace the worn ones?
-Water pump bearings??? Probably not, never heard of one failing on this motor
-Oil Pump??? Probably not, never heard of one needing replacement
-Machine the head???
-Replace the head??? I've read the service manual for replacing valve guides, sounds like I need an oil bath heater... does harbor freight carry one of those (LOL)
-Cam shafts??? I've measured them with a micrometer, they have a bit of wear on them and seem to be half way through their service life, I could just keep using them and replace them on one of my valve jobs
Any thoughts on the things I've listed? Any other considerations?
While I want to do this right, if its going to cost more then $1500 to rebuild the motor, then replacing the motor with a used one will seem much more attractive to me.
