Hoping this is done by spring, we'll be moving soon and I don't want to lose any pieces.
I never have time to post on the forum so bear with me!
Trying to get my valves out today, have the head at work with me here at Napa. Sadly don't have a spring compressor that can reach into the head. Hmmm.
Sorry for lack of forum effort :ambivalence:

Good luck! I'm only a step ahead of you at the moment. My head and cylinders are stripped and at the machine shop.

Nice! I local vintage bike mechanic (and a good one) might have something to get the valves out. None of these here would do it!
 
Yeah, go with the set that Roger posted. I didn't see that one when I was doing mine. I was a nervous wreck using an O2 socket and giant C clamp. It worked, but you have to be careful that the socket stays in line with the bucket and the C clamp doesn't wobble off of the end of the socket.

I got the valves out and today the top end is getting blasted so I can get them painted and ready for assembly. Then I have to paint to lower block, hoping the remaining paint won't make the new coat look ****ty.

At this point I have two weeks to get this bitch back running and on the road... Woo!
 
A C-clamp from Harbor Freight and a piece of PVC with a window cut out of it is all you need to remove the valves.

Hope your media blast guy is plugging all the holes so grit stays out of the oil galleys. If you study the oil path you will mind numerous blind passages that must be kept clean.

Good luck.

I used to do that, in fact, there is even a video of me doing that on BassCliff's site.

I have switched to something a bit more solid. I have a 24mm deep socket that I have cut one side out of. No more bending of the plastic when compressing the valves now.

.
 
I just got my top end back.... Still caked with grease. The guy blasting said he couldn't get them clean with whatever fluid his brother has in the parts washer.

So instead of painting in the next few days, I need to find someone to hot tank them asap so he can blast them for me. Exactly two weeks to moving time and I feel like I'm losing already
 
I've used spray engine cleaner and a high-pressure soapy water nozzle at a car wash to clean lots of GS parts.

Bring a bunch of quarters and blast away.

Of course, this is considerably less than fun if it's below freezing...



And in case anyone's watching and is getting a brilliant idea, don't try pressurized water with an assembled engine -- it will blast through gaskets and get into the engine.

I used the gunk foaming degreaser, several plastic brushes from Harbor Freight and a lot of elbow grease. Once I got most of it cleared, I brought my life savings in quarter form to the local car wash and used the degreaser there. rinse then repeat. I worked on it over several evenings, but I was trying to get it to a paintable surface on my own. I did end up sodablasting the fins on the head and cylinders, did not sodablast on the inside. After that A LOT of washing with dish soap and compressed air
 
Just a quick update!

I have settled in to my new home and workplace, bike filling the basement like I've always dreamed!

AND I NEED AN EXHAUST VALVE.

Cleaning them up getting ready to lap them and..... Exhaust valve 2 is toasted, cracked and all.... Can anyone help me?? I will post pics later

They're still available from Suzuki. About $60, IIRC.

Sorry, I don't have any extras, but post in parts wanted and you'll likely scare some up.
