Re: Well I got the head pulled off!!!
A note of precaution.
By the looks off the pistons, I would say that the top end may be fresh. Old, but fresh. This may indicate a failure of some sort right after rebuild. Not knowing the history one can only assume. Due diligence may be in order to validate the true condition overall.
I am saying this so that if you go just so far and upon start up the true nature of the beast becomes known you won't be kicking yourself in the ass for not going where you had to when it was available to you. I am also not saying that you have to split the crankcase, but the timing train and related item have to be gone over.
How does the head look. The head is so critical and should be considered a hobby in itself.
A lot can be done without the big split or engine removal. You can check the cam and lifters, pull the gearbox, see if the swing arm spindle will take oil and check for free play and freedom of movement.
The lubrication system requires a level of intimacy and study to fully understand.
These bikes, simply put, are an assembly of assemblies and for ease of servicing and to save yourself the feeling of being overwhelmed, should be thought of as such.
