Allan,
This is the first time to hear that a machined yoke was ever available.
Here's some information that might require research to get to where I think your going.
I purchased a frame for the purpose of understanding what tripple sets would fit the Baghira for the use of upside down forks.
What I found was that 1999 through 2003 YZ Yamaha head set races were the same OD as the factorys. The only differents was the longer stem for the YZ. A simple washer was made on a lath to space the upper and lower clamps apart, the bearings and tripples then bolted on as if factory manufactured.
The upper and lower clamps including stem that I used were manufactured by TAG as a set. And I'd note that after market goodness is very cheap these days.
After much thought, while considering explainations shared by others on this forum, I chose not to use the YZ fork assembly as the forks really gained me nothing when compared to stock. I've saved the tripples and forks for an older XT build for some time in the future (I'm guessing that they'll work or can be made to work with little effort.)
As stated in the beginning "...to get to where I think you're going". I've thought at times of finding after market tripples that would fit the Baghiras forks and go through the same process ending up with better bearings and using a higher quality after market head set assembly. And the best part, not expensive or difficult.
Hope this is of some value,
Robert
