RE: Is this any good?
It looks slick, but I can't see what possible use it would be. Look at the size of that huge filter inside, then compare it to the size of the air intakes on the "blower". On an exposed engine like the 5b has, air flow into those intakes may not be too much of a problem, but I suspect that any model with a bodyshell that covers the engine might struggle to breathe properly; air flow under some bodyshells is slightly limited as it is and that intake being so high up might be a problem. But then again, RB Innovations are famous for making supercharging kits for valveless 2-stroke engines, which (from most comments I've read) seem to be about as much use as **** on fish, so, it's probably just another gimmick. And how exactly does it "allow for a cleaner and cooler air charge"? The pictured Baja can't be a running model anyway; did anyone else notice that the fuel line isn't connected to the carb?
