I found some NOS parts lately, so I can hopefully build a "new" Zinger.
Also got the parts for the rear disc brake kit done, together with some wider pegs (same like on my 4-Zinger).
Will post more pics when I get the disc brake parts back from zinc coating, it uses a Wilwood 2 piston kart caliper, will have excellent brake power.
If you need oversize Zinger pistons check out TKRJ from Japan, they have up to +1mm for the "Yamaha 36R Tree Well"
