At a minimum, you caught one in each cylinder.

Its nice to know I have friends like you Greg!

Yup, at least one valve in each cylinder. It's possible too that one or more could have hit hard enough to mess up a valve guide. Possible to that there is damage to a valve seat. So unless you know how take it to a machine shop to get it checked out.

The pistons you should be able to tell if one has a hole in it. But clean the tops of each piston. And look them over very carefully. Look for cracks too. You'll be able to see where the valves hit.

Found some time to work on the bike. I removed the right head. It appears that all exhaust valves are toast and am not sure about intakes. Also each piston now has two smiles faces. What do you guys think? Give me the good, the bad and the ugly!

[sgwilly]

Those smiley faces look like they were cast there and not a result of unwanted impact. I don't see any cracks but you need to look carefully with the light at different angles. From here they look ok.

Certainly that valve is bent. Maybe the slow speed of the starter avoided bad damage to the piston and valve guide.

Going by pics the pistons look ok. To check the intake valves. Set the head so that the intake runners are up. Then pour some rubbing alcohol into the runners. You can use water or gas but I use alcohol. I have it on hand. If the valves are still good the combustion chamber will stay dry. If the valve leaks you know you have an issue. If it pours out you know it's bent. This is an easy quick way to check them before taking the head apart. I would still take them out. Then hopefully just lapping the intakes is all it will need.

Exhaust seats could be damaged slightly. Unless you can tell for sure I'd take it to the machine shop. Have them check them out. Maybe just touch them up. And of course you'll need new valves.

Lesson learned there huh?

I don't know valk, but pretty sure those 'smiles faces' are suppose to be there. Some obvious valves that aren't seated, they're bent. For the ones that 'look' seated, fill the cavity with a liquid, blaster, wd40, seafoam, atf, whatever and see if they leak the fluid out. Might be easier from the back side of the valve.

The "eyebrows" are supposed to be there.

She looks to far gone...better sell it to Me!

Robin,

Is this what they mean by "Home Schooling?"

I assume that I can now turn the crank to clean the pistons? Yes the left belt is connected.

[rogue1000]

Good thread! I'm learning a lot here (of course, you're paying the tab,Pokadot). A valkyrie is next on my list (don't tell my wife!) and this is good schoolin' ! Hang in there, just keep at it...."Keep bungling on" (my favorite saying by W. Churchill)

LO, yeah, but sometimes home schooling gets expensive too. And yes, you can turn the crank now.
