I bought my bike with a damamged cylinder and the top end was in pieces. One of the valves broke and destroyed a cylinder. Got a complete top end off ebay but since it wasn't stored properly it needed a lot of cleaning and prepping. Last week started on getting the replacement parts ready for the install. I'll try posting some pics, let's hope it works.

This is the original head with the broken valves. The LEFT valves were removed by the previous owner's mechanic.

My home made work bench with all the parts (original and replacement) laid out.

The replacememnt cylinders, just finished honing them out. They were very rusty when I got them adn managed to hone them out so they are in ok shape now. Check the ring end gaps while honing and its still in the middle of the spec.

Some more pics.



This is the old damaged cylinder and the old head. The second cylinder from the top is the one that has the damage from the broken valve. Tried to hone it out but the scratches are too deep. However it's a perfect candidate for a re-bore but the old head is nothing more than a expensivepaperweight (it can be fixed but it would cost way too much to do so)

It's nice that the previous owner's mechanic organized all the nuts, bolts and fasteners. It will make my life much easier during re assembly.

The filter box, radiator, coolant lines with the coil and wires. Plus the old head gasket on top.

A shot at the temporary work bench. The old parts are at the front and the replacement ones are at the back. In the middle is the electric drill with the brush bit int it. This worked very well for removing of the carbon from the head and the pistons.

Looks like quite a piece of work. I'm sure you'll be pleased with the final results.

 

Indeed he is doing a great job! can wait until he gets it running again!

 

That bike is worth the effort.
I'd like the name of the mechanic who removed the old valves so I can avoid him..............[X(]
Keep us posted, and good luck with it.

 

Sorry jsut realized I had a typo...it was the left valves that the mechanic removed, the right ones are the broken ones.

I do have the removed valves, spings and retainers. They were nicely put into the box that has the valve cover in. From the looks of things, he did a pretty good job at keepings all the parts in order. He even wrapped the pistons, that are still in the engine, to avoide any possible damage and on top of it all, he pulled the fuse to the starter (so no one can accidenlty bump it while the engine is apart). I don't know who the mechanic was but there are not too many of them in my area but since I do all my own repairs, I don't know any of them.

 

Pulling the starter fuse is a good move.
Seems like he did a proper job then..............
He can sue you later for the typo..........he he

 

Looks like you're have a good time with it. I'm sure it will be good to get it back on the road. I guess you'll have to wait til spring time for better riding weather eh ?

 

looks like your doing a fine job. you get the tentioners figured out?
