The only thing that seems non original is wrong brake levers and muffler. @Ajf has been helping me with a few things and I am forever grateful.
First thing is to clean some of that rust. A little soaking and came out great
Can you explain the chain orientation better? Actually I was just rolling the bike around and the chain fell off. The master link had no clip and would not except a new clip so I installed a new master link.
On my previous Rupp 2 speeds the link and it's retaining clip on the inside chain needs to face the engine and outboard chain link/clip need to face the chain guard. If the clips are installed on the chains facing each other the chains could bind due to the lack of space between the 2 chains.
Hope this helps.
