Been a long time since we heard from you Doc.
What you up too?
I'm a trucker up here in canada and I'm trying to get this bike done to bring with me on the road.I have a sweet spot on my truck and I drive a crane,so getting it on and off the truck is not an issue.I stopped build for awhil but I'm back and am going to finish this beast!I'm hoping to finish by may-june.
Thanks for the info,I did do more research and decided togo with the 1.3:1
Nitrious just needs to be hooked up the end.Slow but going to be worth the wait.
