Top End Rebuild

After compression testing cylinder one was 65 and two was 80 my thinking is to re grind the valves fit new valve stem oil seals and check the piston rings in the barrels for ware. 



New base gasket.

 

Big ends are fine.

  



Fit barrels.

   

Ring to barrel ware was well in tolerance.



Pistons came up nice.

 





Fit valve clamp (with price sticker )

Position on first valve.

     



  
   




Exhaust valve out.



Start grinding.

   

Compress inlet valve.

      

One down three to go.






New stem Oil seals.



What a difference old and new.

  

All looking just like new.

Drop on the head..

   

 

 



 

 Bolt the cam in the correct orientation

      

Tighten head bolts slid in the chain tensions.



  

Fit oil seal, charge reservoirs with oil.



Blue Hermitite the head.


  
   
    







Tighten rocker cover bolts to the correct torq.

Adjust valves, job done.




 

Compression has gone from 65 on one and 80 on the other to 145 and 160. I feel this will increase with a few miles bedding in.

Wiring

The old loom is in good shape.

 Loose fit to check all connections are in the correct place.

Battery box next to fit.

Fit turn signal relay, starter relay, regulator and rectifier to the box.

Engine into Frame

Frame back from the powder coaters. Nice job by Paul again.

Add some padding around the frame to avoid scratching the new paint.

First fit the swing arm but need to fit the rubber shock mounts first.

Rubber shock mounts/Bush and press in with my trusty vice.

Grease on the swing arm top hats.

Ensure swing arm contact point is free of powder coat, again Paul knows his stuff.

Swing arm in next step on with the rear shocks.

One shock on

Both on and looking good. Engine next.

 Half way in with the engine need to move one inch at a time now.

Nearly in place.

Start bolting up engine mounts.

Centrer stand ready.

Foot rest rod next.

 Fit the centre stand pivot pin. (copper grease not rust honest)

New Split pin to hold sideways movement.

10mm Nut and bolt on each side holds the pivot pin in place.

Centrer stand return spring fitted.

Engine in place and up onto centre stand for the remainder of the build.

Starting to look like a bike.
