Can You Run A Gen 1 Motor Without An Airbox?

3WheelerMod

Registered
I am using a Gen 1 Haybusa engine with the following mods

- ECI
- PC III
- 1397 kit
- New valves, spring etc
- clutch mod

Because I am using this in a custom vehicle ... I was thinking just running with velocity stacks/K&N filters something like that... Pro/Cons?

Thanks

yes the Kawabusa ( ZRX Kawasaki with a Gen 1 Hayabusa engine ) has no air box just stacks with screens
 
You should run a wideband O2 sensor, to tune it, with ECU reflash.

And turn off "ram air compensation", which is what it sounds like.
It adds fuel to compensate for the calculated amount of extra air coming into the engine with ram air at high rpms and speeds.
