Freaky, the bike is all totally as it came from the factory except for the DT175 barrel. The engine # is 402-185406 so it's the real deal. Even the 2.75x18 Yokahama front tyre is original equipment. Even the frame paint and tank don't need any repainting. All the bike needs is a good detail a set of tyres and a new 125 top end and you could feasibly race it. It's legal for pre '75 as a flow on I believe.
It may just end up on eBay to help offset the cost of the new Hindall. I've got a NOS Vintage Iron pipe to suit a YZ that'll fit and I've been offered a chrome bore YZa barrel and head or a stocker for when and if I get to doing the little bike up .
