I'm just about to buy a used dyna that worked on one valk but not on another. I'm worried its not going work very long or work at all on my bike. CA, if you talk to the c5 guys tell them others might be interested, especially if there is a way to retard timing for boost or nitrous.

"Right after we made the new Goldwing kit my co-designer passed away and we got incredibly busy. I am running about a week behind on shipping kits so most likely I will resume the 1500 project later this summer. The shaft needs to be completed and is fairly complex. The 1500 cam is hollow with cross drilled oiling holes that presents a unique challenge, but we've got it figured out (I think).
Hang tight until later this year and I will post news as we complete the project.

I suggest more inquiries be made, to let them know there is a major interest.
