Is their any machine work needed? I got a old 440 kit for a xr400 and the sleeve is too large. my 400 cyl with no sleeve isabout 90mm and the piston is 89mm that doesn't leave any room for a sleeve HELP!!!!

I can only tell you what we do for the 440 kits we have to have the cylinder bored to fit the 440 sleeve and then have the sleeve matched to the new piston.

for the 440 stuff we use the Ross piston and I believe it is an LA sleeve.
