Pulled the plugs . put up on center stand put it in 5 gear and turned the motor backwords with the rear wheel. the motor turns free now with a small drag. Drained the oil on debrie in it but a small smell of fuel.

You may need to check the floats in the carbs as this happened on my 82 the other week was full of gas in the jugs

If the needle valve(s) on any of the carburetor float(s) get stuck open, then the associated cylinder will fill with liquid gasoline as soon as the intake valve opens up, if the associated intake valve with regard to the leaking carburetor(s) happen to be in the open position when the engine is stopped or stalls, this happens immediately as the bowl overflows and the gasoline pours down the intake pipe into the cylinder.

This is called hydro-lock. The same principal of how a brake system master cylinder works. Liquids are NON COMPRESSIBLE and the force exerted on the liquid will be transmitted through the liquid to anything that can be moved or compressed. In a brake system that is the brake caliper's piston, which is moved by the fluid being compressed inside the master cylinder by your brake handle, you push the fluid with the piston in the master cylinder, and it in turn pushes the caliper's piston in the brake caliper against the brake pad.

In an engine under hydro-lock, there is nothing to take the transmitted pressure of your piston trying to compress the liquid gasoline inside the cylinder, so it "stops" the engine from moving as soon as the liquid tries to be compressed by the piston. If you remove all the spark plugs and hit the starter in quick short bursts, the hydro-locked cylinder will be revealed and a cloud of gasoline with some liquid is usually seen shooting up out of the spark plug hole(s). After the cloud disappears and the engine will crank normally, you can usually just put the plugs back in and start the engine up with no problems.

When doing this remember that this cloud is COMBUSTIBLE and PLEASE hit the kill switch, to keep any spark plug wires from creating a spark and igniting this mixture, and also DO NOT SMOKE or have any open flames or ignition sources anywhere nearby... doing this outside in the fresh air would be preferred.

Leaking carburetor floats are the main reason many of us keep out fuel tank petcocks turned off when the bike is not being used, this limits the amount of fuel that can leaked into any cylinder and can prevent hydro-lock.

If you haven't already done so, and if this was your "Motor Locked Up" problem, consider rebuilding your carburetors ASAP to prevent leaking floats again.

Just my $0.02 worth....

I pulled the heads and all looks good cylinder and velves. With the heads off I turned the motor over and it locked up can turn it over by hand jest fine but when i use the starter it will lock up. so i'm thinking there is someing wrong in the starter system some were. The starter will run good if i pull it out.
