Thanks Mike.

@2Steve-thanks for the info.  I will give it a try when the that time comes up. 

Opps.  These pics didn't show up.

I finally got them both out. 

I started with evaporust for a few days.  I then switched to PB Blaster.  After a couple of weeks I began the beat down on the pistons.  I got no movement with a rubber mallet and a piece of wood.  I ended up using a hammer and a heavy-duty mason chesil to strike the top of the piston.  That combination seemed to move the pistons a little.

I then decided to put tie straps around the jugs to lift the front part of the engine a centimeter or so off the worktable.  As I struck the pistons, the pistons and engine went down and the jugs came up.  This method made it easier for me.  It still took forever and was not fun.

I am hoping I didn't damage the crank with the beat down??? Anyone know how tough these cranks are??   I did find a little rust in one of the bearings, but the crank turns and is not frozen.




During the process I accidently struck the top of the cylinder/jug.  Picture attached.  Any idea if this jug can still be used again??  The two dings are about a millimeter deep.

Thanks to everyone who chimed in with advice.  It is always greatly appreciated.  I hope the pics show up.
Thanks again,
Russell

Hawaii-Mike, actually the Daytona engine with the stuck pistons is from another Daytona.  The Daytona that I bought from you still looks pretty good.  That engine is currently out of it and has been rebuilt.  It should be back on the road again soon.

Thanks guys for the info.

I'm going to start with evaporust.  I'll be able to pool some on top of one of the two pistons.  The other piston is at the bottom of the cylinder.

Any idea how much it's really worth?  It looks like a fun bike!

I am breaking down a Daytona engine that sat for two plus decades.   Apparently moisture got into the cylinders.  The top of the pistons are visibly rusted.  it looks like the rust is just at the top where the rings are located.

Any ideas on how to free the pistons?

Thanks

I am thinking it's a typo too.  I couldn't imagine anyone selling it for 1,000. 


RDFL-I agree.  That tail section makes the rz look terrible.

I just got my rebuilt crank back today.    John Ritter did the work. 

I am not sure how busy he is.  He is a member here.  Check out the "General Services for Hire" section of the forum home page.

It was easy conversing with John about the process.   

Apparently it sold.  That was fast.

I guess I should post the link.

It is all about timing.  I have been to Havasu four times this past year.  Going to be near there again in July.   Never the right time.

Doesn't look to bad at all.

Nice bike.  At 60 hp, must be a blast to ride! 

I wonder how much it will go for? 

Hey Mike.

Thanks for the suggestion.  Next time I am at City Mill, I'll buy one.
