Maybe I missed it somewhere but are you going with Flat side carbs? are these TMs or PWK?
I cant wait to see this thing run. I will have questions on how you like your carbs, your megacycle cam, and the rs125 forks.
Its a general consensus that these bikes are not worth putting money into but I love seeing people put time, effort, and love into making these little machines better than they were ever designed to be. Great build.
