CB72 - It lives!

I need to ride the thing to see if it's worth pursuing the advance
timing further I think. Being unable to adjust the front brake so I can
push the bike with it off and not push it when it's fully on is proving
somewhat of a challenge at the moment, so no test rides.

 

It's been a while but aren't they behind the points plate? I don't see why
you would have to drop the motor or do anything with the cam.

They're on the camshaft in the middle of the top of the engine, only way
to get them is to drop the engine in the frame so the top cover can be
removed to get access.

It's weird that I don't remember that and I'll be damned if I can think of
any reason to put them there. I'm not disputing your word, it's just plain
weird.

Hmm, ta, <watches> the left silencer on mine has been rechromed but
there are weak spots that are already showing through, mostly hidden by
the footrest.

New exhaust systems are $700 from the US.

 

The points bolt directly onto the head, removing them just reveals more
of the end of the camshaft, to get at anything else the top covers need
removing which means dropping the engine in the frame or removing it
completely. When the top cover is removed you can see the cam lobes, the
tops of the valve springs and the advance mechanism which I think is
around the same place the two parts of the camshaft are locked together.

 

If you don't need a genuine one, there's a chap near me (S. Norfolk) who
will make you stainless steel ones - pipes too.

 

A closer look at the one on ebay shows it's worse than the one I've got.
Definitely interested in stainless ones. Can you pass on his details
please? toastyhamster at hotmail dot com
