Cool bike. For sure a high quality European player. I have a Hero from India, 2004? Completely different carb, clutch, castings. Only thing that really changes over is the manifold and possibly that air box. I’m liking the pedal shaft in your swing-arm. Hero Puch has a provision for it but without pedals. Where’s your petcock?
Took mine racing this weekend. The stock jug has a 45mm treats kit piston in it. I’m rocking a 19 del carb because that’s as far as you should push the stock opening on the Hero 65. Piston pulled to 45 mph with little effort. 14 tooth is on the front only after grinding out the case, a bunch.
