Anybody got a hot tip as to who could supply me some offset keys . I have struck out locally ( no bastard could be bothered even returning my e-mails ) and uncle Ian ( Gowanloch ) hasn't replied either . Im pickin that someone either in Aus or the US will know someone .
Thanks
Hamish

I got mine from Brad Black in Melbourne. I took them out when I got a set of adjustable pulleys, still have them in a box somewhere. From memory one was 5 deg and the other 6 deg. I don't need them any more.
What size are you after?

I need 4 and 8 deg as my lobe centers are at 111 deg and 114 deg . The thinking being that I can fit both and get 106/107 deg lobe centers , or just fit the 4 deg one and have 110/111 deg lobe centers. One thing bugs me is that I get 270 deg duration on the vert cyl and 272 on the horiz cyl. I have done the measurements several times and checked the method heaps ( zero lash , correct TDC , duration at 40 thou valve lift)..... beats me :wacko:
I would rather have adjustable pulleys but they aint as easy to find as you'd think . Epicycle will modify my own pulleys if I send em over the ditch , not sure I can be bothered with that tho.

Cheers

No probs, good to hear that Brad could help you out. :thumbup:
As for the difference in duration, you have come up with the same duration specs that I measured on my bike. I measured mine at least 10 times when I was playing around with the cams but I still came up with the same durations? :dunno:
Maybe Mr Black might chime in here and have an explaination for it.
Good luck with you're new career change as a movie star, break a leg. :lol:
