She started as a mostly complete non runner. Missing some bits, that I didn't think would be hard to find. Engine needed a full rebuild, but I ultimately decided to tear into it myself. Kinda rare machine. been a fun little project.
Heres the "before"

I bought a triumph front fender the same width and the broncs rear, to replace the last 9" that someone had cut off in its well used past. I had a buddy at a paint shop help with the backyard painting duties....and the metal came out pretty good. Its only a rear fender, stays and tank that is painted. Everything else was either blasted and painted black or powder coated black. The seat cover its a two tone grey. Not available. So I asked an eBay vendor that sells reg bantam seats if he'd make one up for me in two tone grey....the anwer was SURE! same price! Not may parts suppliers here in the US, so I had to get the new muffler can, piston and some assorted hardware from the UK. Ignition is going to be an Electrex unit (no lighting) and a Mikuni VM22. I keep the monoblock in the box. Its was pretty well roached anyway.......

two stroke engine with 3 spd. trans pretty easy to rebuild. Internals surprisingly good! primary drive very nasty though.

a few other picts. Interesting note on the Jone WM1 front rim "Not exceeding 250cc" engraved on the rim. I've never seen that note before. But then again, I've never had a small displacement bike with a Jones rim........

Looks the mutts nuts. I love these little broncs. Very rare! Had the chance of buying one a few years ago and wished I did.
