Does Honda still sell those valves?

That'll buff right out.

I saw them on ebay. Have to wait til I get them all checked out before I try to order some.

I liked the 900. It felt big, but not heavy to me, and it was softly sprung. That was great for me as canyon carving is alien to me. I liked the look. It didn't feel underpowered, but couldn't hope to run with my 82 1100EZ.

I got the valves out. Found another slightly damaged. You can see the little nick at about 1 o'clock.



Here's what the exhaust valve seats look like on cylinder #3. That's where the above damaged valve came from.



Typical valves, Intake on left, exhaust on right.

Holy Carbon! That thing must have looked like a 2 stroke going down the road...

Makes me wonder about the rest of the engine, as somebody obviously never changed the oil or engaged in any form of maintenance.

[JamesWhut?]

Yeah... that's not gonna lap out.

Start looking for a new head with valves. It'll be easier and cheaper than trying to restore that one.

update.... i just got this bike running last nite. haven't worked on it a lot cuz it's a pain to work on and it's depressing. i've taken to calling it "satan's honda". but it's running and i've ordered a battery and rear brake pads so that in a couple days i should be able to try riding it.

i really wouldn't have even bothered but it's in such nice shape. 17000 miles, looks like never dropped and new tires. and we got it cheap.
