Hi,

After lying for several years I went to turn engine over on my RD400 E and its locked up. Have tried Wd40 down spark plug hole but no joy.

Any ideas on how to free this.

Once I get if freed should I strip engine and rebuild crank ?

Take the heads off and have a look, only takes afew minutes and will let you see what's going on in the barrel. If that doesn't work lift the barrel off too

might want to leave it soaking for a few weeks in diesel oil. not too much though.

I think that you would need to strip the pistons down and free off the rings and check the bores for rust damage.
