Hey Chris, Gruff thanks for the props. As for your questions Chris, the race gears were a couple thousands of an inch too large of an I.D. to fit directly on my NU50 shaft. I don't know for sure, maybe mine were made for Dio or another Honda model still more obscure. I got them from Shannon Hall, and just thought they were the same "race gears" everybody else has been trying on their Urbans, so don't quote me on the name. Differences between them include 14t final drive (vs. 17t stock) and a straight cut gear bevel vs. the angled ones that came stock. Naz ended up welding the gears to a spare rear shaft I had that I had bought off fleabay for that purpose. If for any reason the modded gears blow up or separate from the stock NU shaft, I have a complete set of stocker gears to put back in. That said, everything feels solid and we anticipate no problems with them long term. To check for deterioration of the mating, I will change the final drive gear oil out a couple times here over the next couple hundred miles and look for shavings in the juice. I'll let you guys know if there are any issues but things seem fine for now.
As for the TJT plate- I'm trippin'- pretty sure it was made for Caminos, sorry for the confusion. In order to get that to work, we had to weld in a small washer into the hole in the center of the plate, as the inner hole was a bit large for the NU variator shaft. Naz machined out a hole the correct size for the shaft and, all is working very well now with minimal hang up top when decelerating, which was a huge issue with the notched variator.
