I run plastic bushes in all my rebuilds since mid 90's. Even in my race bike. I use a plastic called oilon or Nylacast the green version as its impregnated with a type of grease.

Oh my word, I think I just had a trouser movement...

Get a good photo of the two cams you have installed on here for us to look at please.

Just for the record, the NA cam will not give you any more power, your best bet will be to get a Turbo cam back in.

The base circle on a NA cam will be bigger so the Turbo valve must have been moded or installed at a different height. The chances of now fitting a STD Turbo (Z650) cam straight into the head will be highly unlikely.

Either the valve will have been tipped (having a small amount removed from the ...

did you also open up the hole in the case to clear the thread??

Yes and no, I opened up the hole so I could tap the case so it was belt and braces.

I screwed the new boss into the case then tightened the nut onto the inner face of the case.

Do you have to split the cases to get to the backside like that? mines busted off but for now i'm just dealing with the slight harley oil leak from the cover

You do really to do a proper job.

I have used Q-Bond with good success but that's when I have the broken part to glue back on.

If you do ...

Do you want a drawing then...

Yes that would be great! I won't be doing it but the guy in TN that machines these cases will most likely be happy to have it. Thanks!
