3CL steering head bearing pre-load

Hi Tom

The oil currently am using is 15W ( a secret recipe from Proven products ). I bought it, well they sold it to me when I bought a kit to rebuild the Koni's which are in my shed at the last Barry as it goes.. so I figured would use the oil in the Ceriani's instead.
Reckon it runs around just under 1/2 a cup per shock ( 100 ml ), done two sets and still have a bit more than half the bottle left and its a litre bottle ..

Here's what I do, start by kind of  filling the shock bodies to almost the top then put the piston and rod in and slowly push them to the bottom, which sees the excess oil spill out Good to put a rag under or try to catch the oil..... Then I like to let a little more seep out as I  get the cap on and slowly tighten it down.  I know not really scientific but it seems to work asyou gotta try to get just the minimum out as you don't want an air gap.

Seem to remember another post about Ceriani rear shocks and oils so maybe if you search you can find it as there is most likely a better way to do it.  :o
 
Oh and another one thing I like to leave the head stock set up as top ball and lower taper... in fact when I rebuilt the Cico I did just that too. just got to duck now as am sure there will be those who like oil and tyres have their own idea's....................
 
My Ceriani rears are like OEM never been opened or rebuilt. I will put focus on getting konis rebuilt. need to buy the extended top for the extra length from Guzzi to Breganze. But, why would they be the issue? OK with original setup. Deceleration (the head shaking) does not use more than the 40mm travel with the current setup in the front than what I had before.

It has to be front end.

Interesting about tapered bottom, roller top. Paul told me the other day about that with his Jota, Said it was shit with tapered top and bottom.

Will take it for a run soon. Lord of the Lakes at Lakeside next weekend. Maybe not so soon.
