Keihin PWK carburetor upgrade on MZ Skorpion Sport

[uberloop]

Playing around with some cheap carburetor knockoff upgrades.
One is a single 42mm Keihin PWK on an intake adapter.
Another one is two carbs 40mm AND 30mm PWK on stock intakes. Had to add 90 degree cable guides to clear the bottom of the fuel tank and modify some throttle cables. It's a very tight fit but it works. Utilizes stock choke cable for ease of use.
They both rip!

Please tell us more about the intake adaptor for the single Carb.

Adapter shown in picture above was machined by a friend of mine who owned this bike back in the 1990's. I toyed with the idea of re-making them but it's rather cost prohibitive.
I'm now experimenting with fabricating an adapter for short Grizzly 660 intake manifold but I'm stalled mid-way in the project because these two bikes are so much fun to ride.

Come on you`ve got to tell us more about how they both run!
