Hello all. I have been peeking on your forums over the last few months while resurrecting my dad's 69 sandcast. Lots of useful information on here. Decided to join in on the fun.
Nice! If that is a real sand cast, you would increase it's value significantly by bringing it back to stock. That's not a stock paint color, exhaust, seat, or carbs. The sand cast MH300 exhaust will run you $2K+, but I've watched sand cast models fetch $15K and up.
I think it was originally red. I already plan on replacing the seat with a stock one. I'm not a big fan of this seat at all. I'm fine with the RC 4-1. Also need to source some bigger jets, she is lean. Rides really nice though.
