Its an XS 650 site, but this falls into the "other brands" category. Moderators, tell me to cease and desist if this thread is inappropriate for this site.
Many moons ago when I bought my son's first bike (a Yamaha PW 50), I got a Rupp minibike sorta rolling chassis thrown into the deal. Thoroughly trashed, but still straight and in many ways largely complete. I needed a small-scale project with fab work, so decided to have a go at doing a Rupp restomod. Looks like this, with some new rear shocks of dubious origin on it:
Then there was this B&S 5 hp engine floating around the shop. It got a full rebuild with a new piston/rings, new guides and valves, a ported block including "shaving the eyebrows", a heavily-milled cylinder head (on the lathe) and a Mikuni knock-off carb on a custom-made stainless intake manifold. Looks like this:
The engine runs very well on a test stand; lots of compression and very responsive.
More installments to follow if it amuses the readership here.
