Erm... no haha. Engine is seized after standing for nearly 20 years. Found a decent rolling frame so the black one is likely to be a donor now

This is the new bike. The black one has been broken up to build this bike up. Time to start stripping it to a frame to get it painted

Looks like a fun project!
I'm sure it's the early one which is about 19bhp. The frame is now waiting to be blasted, tried cleaning it with a cup brush but still takes forever. In the mean time I can pull the head off the engine

I took the head off tonight to find this mess given in a soaking in wd and I'm hoping it will unseize itself. The pistons are scrap, a piece of the ring has smashed into the top of the right piston at the top

Forget WD-40. Use a 50/50 mix of acetone and ATF, it will penetrate past the rings eventually, where the WD-40 won't. It may take a while, I think it took 5-6 days for it to pass the rings when I was rebuilding the XL350.
Was the plug on that RH cylinder left out? Hopefully none of the moisture made it past the rings.

Will try that and hopefully I can free it off, yes the plug was left out, it had sand, dirt and rust in there 
I don't have another pic at the moment. It's the right cylinder in the picture, at the top of the piston between the studs, there is a hole the same size and shape as a piston ring

Frame has been blasted, I have welded the rear hoop on since this picture and it's going to be blasted again to give an even finish and remove the small bits of rust and dirt I missed the first time

Few brackets added, the rear hoop added and a coat of primer

The frame is looking good now, shame I can't say the same for the engine :/
