Iíve been slowly working on this restomod when Iíve had time and itís pretty much done. 
Every single part was either refurbished to look new or replaced.  Iíve got lots of pics of the process but hereís one from today next to its much younger cousin
It runs and ride great!
Engine & Transmission / Re: Oil Pump Assembly
« Last post by oly507 on October 17, 2018, 01:52:16 PM »
Sorry.  Just realized the rotor assemblies are of different heights so they can only go in one way.  Am I to assume the arrows on the one rotor assembly point up?

I have a couple of questions concerning the re-assembly of the oil pump on my '73 TX500.  One rotor assembly has a arrow stamped on each piece and I understand they should be aligned on re-assembly.  Does this rotor assembly fit into the case or the rotor housing?  Also, the inner part of the assembly is machined out.  Does it face up or down?  The other rotor assembly does not have any markings on the two pieces.  Once again, does it fit in the case or the rotor housing?  Thanks in advance for any help I receive.  Rich

The base gasket and head gasket are different shapes. You'll figure it out.

Valves are on there way back, re-cut and vaccum tested so should be perfect and good to go. I finally got the right rings, both installed and will be getting this all put back together and hope and pray I did everything right. if anyone can answer my question below that would be great. thank you!

Okay, to make it a little easier, I have attached a photograph (I think) which I liberated from google of an OEM shock absorber for a TX500, 500A, XS500B, on which I have marked the two measurements I am chasing... If someone with with an original shock absorbers would be so kind as to quickly put a rule against theirs and give me the two measurements (A & B), I would be ever so grateful.

The pointer must be reset to align with the T left mark when the left piston is exactly at top dead center. You will need either a dial indicator or a piston stop tool to find TDC.

thanks you  for your reply,

 i bought the bike as it with a fresh head just rebuild.  the cranckcase dont seems to be allready open so i dont thin the breaker shaft has  been touch, but  The governor has been mooved i guess, because the paint-lock on the screw have been brock.
First should i try to time the governor ? don't you know how to?
best regards

Welcome Remi. Were the governor assembly and or the breaker shaft removed during this repair? If so are you certain that the breaker shaft was timed correctly and the governor assembly assembled using the locating pin?  If those are correct the can timing should follow just as you described.

hello, i'm Remi i live in canada and i just had a 77 500 xs.
I have always been passionate about this model and I was lucky to find one

 following a head rebuild it's impossible for me to time up the engine, i explain: i respect all the steps of the owner manual, put the left piston at the top, then go on the  "V" Mark and assemble the camshaft marks with the mark of the caps. but from the first turn of the engine (by hand) the left piston hits the intake valve. I do not understand what is going on, one of you has already encountered this problem.
please excuse my english this is not my first language
