Oh, I'll have to see if I can locate an O ring for that.
Thanks

Had some time today so I spend it on the chopper.

Motor needed to come out for gaskets and such.
Came out without much fuss, way easier then a stock frame!
Bunch of parts already here, bunch more to order.

Chopper frames are awesome like that! It's also nice to be able to tear down the entire top end with the engine still IN the frame!

Yeah, if it was just the top end I wouldn't have pulled it.  Would have been so easy.

Got the top end off.
Not a lot of good news...
At some point the motor kind of ate one of the tensioners...




Some oil starvation..


Very broken.



I assume Honda doesn't make these any more either.  So on the hunt for a replacement.
Also going to need to find the rest of the broken parts in the engine.

Yeah I planed to run a some sort of performance cam.
With the prices of 650 cams being what they are, I might just buy a web.

Need to sort the tensioner first though...

Honestly I don't know what happened.
Ran fine and didn't hear an issue.

No that's not the part.

I roasted a cam on my 750 due to oil starvation.  When you get it all back together, leave the valve cover off and kick it over until you see the top end getting lubricated properly.  Peace of mind...

New cam chain guide vs old one



And a broken valve guide...
Wasn't happy to find this, along with the bent valve that caused it.
Just more parts to replace and work to do.
Not 100% sure what the plan should be, or will be for this yet.

Yeah.

Replacing valve guides isn't really a DIY job either....
Was trying to keep cost down on this build.

Trying to price out parts now

But then again the cam bearings don't look so hot.
Anyone got a good head?

Why isn't it a DIY job? I did the guides on my 78F.  Really not that hard at all!

It looks like that chain slider was installed backwards- the chain shoulda been on the flat side, but all the wear marks are on the "humped" side!

Scored a replacement head on ebay a while back.
Stripped and rebuilt it so that solves one issue.

Need to rince out the gunk from the bottom end of the motor.  Also make sure no passages are blocked.
Then the motor can go back together and in.

As always I am behind the time frame I was hoping for, but at least im still having fun

Time frames shift. Did you get the new chain slider in the right way?

I do have a new slider, and will be installing it correctly.

Don't actually think it was actually installed backwards before, I think it was damaged and turned inside the engine.

So I'm still plugging away on this thing.
Graduated, now I'm an engineer!  Mechanical with an aerospace concentration.
On job hunt now.

Mostly been riding my 1100f.
Was mildly looking for a complete replacement engine as to not waste more time.

Got a timing chain, but I don't have a riveter.  Don't really want to spend the money on one, but unsure if there is another way.
