My buddy has a FB. Had a Yamaha in it and he just converted it to GXR power. The chassis itself is a clone of some kind, I don't remember of what.
With the Yamaha the air intake comes in through the roll bar opening, looking similar to a Formula 1 car. It just dumped in to the engine compartment.
Right now he's using the stock GXR air box. The air comes in and dumps into the engine compartment. The air comes into the engine through the stock air box openings and through the air filter and to the engine.
He kind of likes this because, being in the North West and our rainy weather, the rain can't get to the intakes. At least not easily.
I think the motor would run better if we basically took the top off the stock air box, glassed a 'scoop' to catch the incoming air from the roll hoop opening and ram it into the motor.
His concern is the rain water getting into the intakes
Is that a concern?
If so how do you get around the problem.
Thanks in advance !
