Nice job, I'm actually working on my project CR500 swap.
I have to deal with making clearance for the carb and changing swinarm geometry.
I have 2 swing arms I toying with, TRX450 and CR250, the TRX needs the main pivot changed to go narrowerand except the 17mm pivot bolt, the CR fits in with just a 0.155" spacer but unless I want to make it a 3 wheeler I need to graft on the bearing carrier.
Still along ways off from riding but I still have a couple machines to keep me going
