The Pursang was first sold in 1965 as a 125cc two stroke. It was also sold as a 250cc and by 1974 as a 360cc. This 1975 360's engine has been replaced, but has been rebuilt with a new jug and piston as well as polished to an inch of its life.
The restorer seems to have sweated some of the details, the shot of the carb shows new boots and either new or re-plated clamps between the airbox and intake. Oftentimes, people try to reuse the original cracked and scabby ones.
The seat looks to have been recovered, however the Bultaco logo was left off. I'm sure you can get a stencil to put it on. Surprisingly, there are a few sources in the U.S. for vintage Bultaco parts.
The pipe also looks to be either a nicely restored, custom repro or NOS pipe. Often, these are replaced with something that works, but looks too modern or fabricated by Uncle Joe.
The only downside with this bike is that it is sold on a bill of sale, so you may have to do the "lost title" dance with your local DMV if you need a title to use it at an ORV area in your state.
