Bead blasting is best. It can get into all the crevasses on the cylinders and the head. Here is an example of what it will look like.

Gotta be careful with glass bead because it can get into the blind oil passages. My preference is soda for that reason. Or maybe get it hydro blasted from that sponsor of ours. That looks pretty killer when done.

A 50lb bag of soda cost just under $50 at HF. Good thing it's water soluble. Does a great job of cleaning aluminum.

What do you use to shoot your soda media with Steve?
Also
Looks pretty close to flat what's the tolerance on the surface?
The jug is still stuck on to the cases pretty firmly. Pull it and replace the base gasket?> Yes, or no?
Not looking forward to trying to compress the rings and reset the pistons if I don't have too.....

Nessism do you clear coat it when it's been blasted, or leave it naked?

Wow it's made here in Nashville! Or at least the Kano Labs is here.

I have a cheap sand blaster attachment. It works great. How many miles on the bike? If you disturbed the base gasket it will leak. You MUST get all the carbon out of the cylinders. The tolerance is .004 using a straight edge across the deck and head surfaces measuring in an X and cross pattern.

Hey Steve, not to be argumentative, but wasn't there something said in the past about leaving the carbon ridge alone at the top of the cylinders if you weren't going to take the cylinder block off? I could swear I recall someone mentioning that fact. The only reason I bring this up is that it sounds like Greybeard doesn't want to take the jugs off so therefore he may not want to mess with the carbon ring. However he must be certain he hasn't broken the base gasket seal. When I first started my KZ-1000 project I was trying to avoid removing the cylinder block, but I did remove the carbon ridge at the tops of the cylinders. Someone here said that wasn't a good idea and to leave it alone if I wasn't going to pull off the block. At least that's what I remember, but could be wrong. In the end my block came off.

The odometer has 28,000 and change.
Once my valve spring compressor arrives I'll pull the valves and have the head media blasted.
I'll ask a friend to run the valves through his ultrasonic cleaner and see if that doesn't get all the rest of the carbon clear.
Guess I'll be pulling the block and have it media blasted too...

Have fun removing the old base gasket material! It was a real PITA to scrape off. Found it's easier when you remove the studs but not required.

yea I already ordered APE studs.
I beat the crap out of my impact driver. I was using a 5 pound mini sledge and hitting it as hard as this weak ass old man could muster with one hand on each tool.
Seriously ridiculous how hard it was to get the cam caps and the head caps loose.
Going deeper than I want for sure.
Both $$$s and into the motor.

That was me. It looks like he disturbed the carbon on the pistons and it seems the rings are leaking. Could wash the bores with diesel by filling them then vacuuming them out but it has to be done until all of it is gone.

Don't blast the valve seats. I leave the valves in until I'm ready to lap them. At that point a little cleaning can be done being careful to not hit the seats. Maybe if the compression comes up the rings will seal.
