I can source new valves, seals and carby rubbers from the states for just under $500.00 shipped, so probably won't bother with a used motor...I've got it all torn down ( looks very sad  :'( ) and cleaning up while waiting for parts.


How are the pistons looking? Wot thuh

I only ask as they are only bog ordinary alloy forgings and as such are quite soft, they don't need to be anything more. But there inlays the conundrum...any wack to the top of em usually results in a bruising which invariable results pinching the top compression ring in it's groove and occasionally the second and oil rings as well...quite common in motorcycle engines  :-[.

Anyway just a thought...and if you are looking...http://www.ebay.com/itm/1993-Honda-ST1100-ST-1100-Pistons-and-Connecting-Rods-/120882775607 :wink1

...hence my post on considering an engine replacement / refurbishment

Ciao the can :-)

They look pretty good. When I took the heads off, there was only the smallest of marks on the top of the pistons where the indents are that correspond to each valve. It seems that once the valves had bent, they didn't touch anymore, and it didn't run very far before I pulled the clutch. So they should be OK.

Thanks for the info though.
Cheers

Thirty bucks for 4 pistons, rods etc.  He's not out to get rich quick!

You're right about that Biggles. Even with the $60 odd dollar shipping.

Anyway here's a couple of pics of the heads and pistons after dismantled and cleaned up.









The carbon build up was minimal on both the pistons and heads. The valve seats on the exhaust valves were not the cleanest, but that will be remedied with the new valves of course.

Well all happy again. The ST back up and running. Purring like it never happened!!

Didn't get a chance for pics other than those already posted. Pretty straight forward job really. Only a few little odd bits here and there. Happy to help anyone who decides they want to get that deep into their engine (or needs to  :'( ).

Ya gotta love the engineering though.

 :wht11  (BTW we need a silver ST1100 here).

Well done on the open heart surgery.  A bit of a pioneering there.
Hope no one else has to pick your brains.
Just heed your experience and change the belt at 120,000 kays or live in hope.
Seems you can get away with it for quite a long while, but then...

Thought I better update on the patient recovery.

All running well and have now put close to 1000 kms on the rebuild. Things are settling in nicely and the slight ticking of the valves is reducing every time I ride ( I set the valve clearances at max to allow for the valves to seat in ).

Next job is to sync the carbs which needed doing before the rebuild anyway.

Now to get some more rides in and get it all back to normal. Love being able to run in at highway speeds  :runyay
