Take its head off??

<< < (2/3) > >>

JonnyB:
Be carfull when removing the head, there are a couple of oil seals under the cam carriers

SteveD CB500K0:
If you take the head off you will have to do the barrels too (they'll never reseal once slackened).

Get a top-end gasket set - they're all in there.

Bryanj:
+1 on the set as you will need new "pucks" and "O" rings

Seamus:
Thanks folks, I will order from DS tomorrow.

You might also want to think about investing in a thread repair kit. 

I dunno how common this experience is, but I've found that some of the threads in the head are incredibly fragile, and it doesn't take a great deal of effort to strip them out.  Simply retapping the holes doesn't work, and it's a pain in the ar$e to get 95% of the rebuild done only to find that some of the bolts don't torque down.

The upside is that drilling and tapping in the new threads is pretty simple and doesn't require any special skills - just a steady hand with a drill.

And if you take the barrels off, pay particular attention to reseating the large O-rings that fit round the bottom of the cylinders.  If they go in wonky, they'll leak oil.

Hope that helps

Neil
