So my 18yo son wants to get on the track with me. He found a 2002 Ninja 250 put out by a shop because it was abandoned. We picked it up brought it home.

NO visible signs of engine damage, someone put clean oil in it. Chain is heavily rusted, swingarm and clipons also show signs of rust. Tires are very cracked. My guess is it has been sitting outside for a long time. 22K miles on the odo.

I took the cap off the stator cover and tried to rotate engine by hand. Wont budge. Pulled spark plugs and sprayed WD40 and some penetrating oil last night. Still wont budge.

I have torn apart my 2009 motor before to switch a crankcase with help from the nice folks here. I have a feeling I will have to drop the motor and crack it open to see whats going on. Anything else I should look at / try before I drop the motor? Thanks!
