Turbo for carbed bike?

[hollycow]

Does anyone offer a turbo kit for carbed bikes? Someone on here said KMS was building a turbo kit for their 570 ktm which sounds like a carbed RFS motor.
Seen a lot of blow through systems on cars, but with a single barrel carb seems like you would not be able to add enough fuel. Maybe you could use a dial-a-jet or intellajet kit with two nozzels. I guess you could also add an injector with a tps signal, a/f sensor, fuel pump and control box but then you might as well remove the carb. Was interested in a RFS application. Thumper Racing has built a turbo RFS with modified CRF injection. The 07 Sherco RFS comes with injection you could probably pilfer parts off that. Just woundering if anybody has turboed a modern carbed big bore with any success. I know in the long run it is probably just cheaper to start with an injected bike.

You could make a carbed bike to work with a turbo but it's not as easy and tunable as on a injected.
If you're about to put that much $$ into a bike for a turbo system I would start with a fairly fresh injected bike instead of an older carbed bike.

Doing a carbed turbo would be pretty straight forward with the right carb. We all ran turboed Rx1s and Vectors for years and they ran great. All that is needed is a boost reference line to the carb which will pressurize the float bowl and drive in the additional fuel as well as a fuel pressure regulator controlled by boost and likely an electric fuel pump. I had toyed around with using one Rx1 carb but I never looked into it any further. Nice thing about the Rx1 carb is it has both an electric heater and a coolant line heater built right into the carb.
