Make sure you get in touch with member, Elan, and pick up his Oil Pump rebuild kit. He has the NLA o-rings and internals (not rotor) that you will need.

Thanks for the info! I reached out to him and he directed me to his kit on ebay.

Here is the link for other: http://www.ebay.com/itm/162179190728

They really are gorgeous.  You have to be getting excited to put this thing back together. 
This is going to be one really sweet bike when it's rideable.  Looking forward to seeing it street-ready.

thanks, and yes, I cant wait to get it down to Racetech so they can start making my monoshock!  Then I just have to choose a color scheme, tank fab work, assemble the entire engine..  :-[ I guess I'm still a long way away haha

I did get plates cut out for the monoshock mounting to the swing arm and up under the tank  8)

Continuing to enjoy this thread.  Your beautiful swingarm hoop back on page 15 -- what tools / techniques did you use to bend that up? thx!

Just a manual bender using a 5" radius.  I didn't have a bender at my shop so I made a bunch of measurements and emailed it to my GFs dad (the one who is building that truck featured a few pages back).

Here are the plans I made and sent him:

I know right, Nils takes SO LONG to turn parts around  ::)

In seriousness I'm not sure how he get things done so quickly, but Im not going to complain about it  8)

I also just realized this build turned one-year-old last month  :'( My baby is growing up so fast.
