Fyi 81 gs400l gaskets from a gs450 kit

[Mekanix]

Hi, This is just for information as I rebuild my engine for those out there doing the same and not finding parts very easily.

In a 81-83 gs450 gasket kit you can use :

head gasket

cylinder base gasket

cylinder base o-rings

mag cover gasket

ignitor cover gasket

clutch cover gasket

intake o-rings

exhaust crush rings

lower oil drain cover gasket

cam chain tensioner gasket



Things you cant use from the kit are

valve seals

valve cover gasket

valve cover breather gasket

various head bolt washers


And that's about it. 450 kits are allot easier to get than the 400's which I havn't found to exist yet.

All you would need now is :

a valve cover gasket

breather cover gasket.

5 case seals ( crank x2, gear selector, sprocket and clutch pushrod )

8 valve seals


hope this helps someone

Hi,

That is great information for the 400 owners here. They're always complaining!


Thank you for your indulgence,

It is a lot easier to find the 81+ 400 kits from euro/UK ebay sellers. I got one for 15 bucks shipped.

Only problem I have found is almost ALL the kits use the 1981 (maybe 82) valve cover gasket, and they changed it a bit for the later years (and of course that is the gasket I needed.) not sure why all the kits have the 1981 gasket when it was the same from 1982-1986

Yeah I got one of those from an 82 kit and it has 6 extra holes, so I just trimmed it and it fits all the existing holes and the gasket works fine but I have the right one on order.

And I've been all over e-bay looking for anything for this bike, so far nothing really stands out , but there is allot of 77-79 parts out there.
