That pic looks like a plan to get tin foil, zip ties, custom polished rockers, and a tartan (aka "all things ScooterBob) into one shot.  Was there a glass of whiskey I missed?

That's not keeping the mice out!  It's inviting the Irish mice in!

  And pretty much a MUST when working on the top end of these bikes..... Is a nice  long reach magnet.  Those head stud nuts LOVE to fall down the push rod tunnels, on the right side, as your putting them on.  Beats pulling the head back off ...... just sayin'  ::)

I've seen more than a couple of those nuts "Factory Installed" on top of the lifters .......  :-\

    Besides keeping the Gub'mint at bay  ;)......  That foam/foil insulating wrap, works nice on fuel lines that come close to heat sources.





   Damn ScooterBob !!  THAT...  is some BIG lift on those Hotrod cams...  Gotta work some math now.... and figure out how many sections of head gasket I need.

  And some handy marks made on the rotor for easier valve adjustment......

What deck height did you end up with ...... I'm curious. I'm GUESSING about .015" down in the hole? A stocker is around .040". We don't any of those compressions to get out, you know!  ;D

   Don't think we have to worry about that Cuz..... NICE work I must say !  ;)  More like ....005  EXcellent !

  Sooo... all socked down with stock base gasket and three sectioned stock head gasket.. we come up with....

   65- 70 thou valve to piston clearance at TDC... And puts us in the quench band at 60 thou.. With a little wiggle room on the three sectioned gasket. Think I'll give it a go like this first....

  Whelp.... after a LONG cold 7 day work week last week.. I was able to get back on it today.  And i was able to button up the top end.  And it IS  a nice bump in compression.   And I have NO doubt that the that the AVL piston crown will look as clean as the stocker did, with ScooterBobs combustion chamber design  ;)

  A few more pics.... not comprehensive, but just as I go along..


   Copper sprayed head gasket...reused and in perfect shape.

   Sliding the head nuts down to the studs, using a long thin screw driver shaft , makes things easier.   There are TWO nuts under the rockers.... so if you don't see 'em? You need to take the rockers blocks off !  And.... torquing them down crosswise.  I like to sneak up on the torgue spec ...give the head a few TAPS with the mallet, then finish off torquing it down.   Let the head sit for a while.... then check the torque again.

I use the mag tool to start those.  If they thread then the mag pulls right off :)

   And something to be aware of when reinstalling the intake. Make sure that curved notch , on the insulator does not have left over material left on it from manufacture... And lines up WITH THE INJECTOR !   Head buttoned up and back to work.....
