does any body know, if you can get different thickness base gaskets, like the yzf kit ones, or has anybody used 2 or more standard ones together on there motors. 3tj by the way ?

They can do a base gasket for the yzf whatever thickness you need. I'm about to order a 3.5mm one for the 727cc engine i'm building.
Only problem is the postage from America

Hey Steve ... is the thicker base gasket reusable ???
If not would it be better to get an alloy plate cnc cut and use 2 gaskets ... that would give you some rebuildability.
Otherwise - How about we buy a few between the interested parties (I'm in) and share the total costs ???

Well evil my pistons should turn up tomorrow, though I wont be able to measure them until thurs as I have CCS tomorrow

then a leaving do to go to. But as soon as i've measured i'll put a post up and order a few then.
They are made from copper, so are softer than ally but can take a higher temp. If the head is torqued up correctly i think you could use them again but measure them first

maybe add a normal base gasket if it has contracted slightly.
You seem well up for the 727 Boris, think they could be a monster, maybe as fast as a new 600.

Definately up for the 720 ... I've got a 4JH in the garage as we speak. Do your pistons raise compression too ??? Let me know how much the gaskets are + postage
Did you get the pistons from TTS ??? I'll try and see them at the Excel Show and order them there.
On a similar subject ... I finally got a set of versize pistons for my SB6 1146cc and a bit of a raise in compression to 12.9 so a bit like you I've got bits of engine in different places of my flat.
