Is this included in the XS400 Athena 27 peice complete Gasket set?

My mechanic said "yeh if its top and bottom end, it should". but OldBikeBarn says no.

Already bought one off partsnmore.com for other gaskets, but not sure about that one i need.

If the gasket set doesn't include it, anyone got a link to get 1978 XS400 valve/rocker cover gasket.

Thanks,

Ari

there isn't any.

think about it, you have the camshaft running in two halves and with gaps measured in the thou'. why would they ( yamaha)stick a 1-3mm gasket in there which squishes to whatever the gasket wants?

you even have to ensure the top cover and cyl head have the same machining numbers or you'll have a seized camshaft.

there are 2 schools of thought on sealing this;

1) use nothing and ensure all surfaces are spotless and true

2) use yamaha herme seal/wellseal very very sparingly ( as in official yam service manual)

i have done both and ATM have the wellseal on with no probs

drewps

use Yamaha 3 or 3 bond, same stuff just without/the yamaha logo on it.

This is the actual specified sealant.

Wellseal is best used with paper gaskets - it the best stuff for eliminating misty base gaskets.

k thanks guys!
