Clutch & cam chain repairs

[trosco]

Hi all. My 07 turned over 31,000 on the way back from Eureka Springs Ark Sunday. I plan to do the cam chain extenders in the next couple weeks as both are fully extended. I have the new pieces from Chuckster (2 for $35) and got new gaskets (2 @ $4 each) and O rings (2 @ $3 each) from Maw Kaw.
I was considering doing the clutch spring upgrade at the same time. Maw kaw wants $34 for the engine cover gasket and $31 for the early Mean Streak spring. Was going to grab new exhaust gaskets at the same time and Kaw wants $8 a piece for them. Used the part in our list for gaskets from Harley and that is not even close to the same gasket as Kaws. And the Harley dealer in town won't order the Barnett Spring for me cause they don't want to be liable for me using it on something other than a Harley.
So here's my question: anyone got any good sources for the Barnett or Kaw springs, engine cover gaskets and/or exhaust gaskets?
