Sandblasting - preparation & after

The Mid section removal

This was fun to do, but very slowly, not to scratch the cylinders, or to brake off the air fin's on the block. It well well..............

Engine being taking apart in pieces

This was the fun part, to see the interior of the engine. Once inside, the current condition would make the final decision to either abort the rebuilt project because of cost, or continue on!
It turned out that the two cylinders on the left side had a lot of carbon, however no sign of corrossion.

Once I was able to slowly remove the cylinder head and mid sections, i discovered that it was in a condition that was good. The only sign of concern, was one cylinder had surface rust a little on one area. However, depending on the measurements once a gauge is used, i will either hone it down, or rebore it completely.

The valves seems rusted, so will try to get them out with a closer look. Tried to remove them with a C-CLAMP, however no luck. Will need to bring to a machine shop to remove them i think.

Tomorow i will be sandblasting the top-end. Tonight i put masking tape on all exposed ports and internal points before the sandblasting starts.

Engine disassembly was quite a job

Because the engine had not been started for quite a few years, it was hard to get some engine mounting bolts to turn. The front ones i was able to turn after lots of WD40 and RUST PENETRATING GEL. However, the lower rear mounting bolt on the engine, after much frustration, i had to use a hack saw metal blade, between my two fingers, under the frame of the bike......and took me 1 hour of paintaking strokes to cut throught it!

However, i was only able to remove one  end of the bolt, the other end was completely rusted in the shaft of the DAMPER, which is a metal shaft also. The pics show the actual bolt head and damper that was affected.

After much WD40 and RUST PENETRATING GEL, i decided the solution was to grind the head down completely with a electric grinder........IT WORKED!

This is with the exhaust removed. Has two bolts that are broken in the block. I will need to drill them out and re-tread them.

The bike in my garage

This is the bike just before and after starting to disassemble it completely.
