B. The, "extensive research" you claim to have done that made the use of an aluminum baseplate, "unacceptable" seemingly didn't include any findings nor recommendations on efi mapping nor jetting... none, nor included the realization that your product shattered with heat and vibration...and pretty much flies in the face of 90%+ of the entire countries race teams who construct their air filter mounts out of aluminum.
C. You made the bottom plate out of plastic because, employing the method of connection that you do to the KTM's plastic carb intakes, metal would wear these due to the motor's vibration exacerbated by your design's loose method of connection. Plastic is not better than aluminum nor did you use it for reasons of heat soak, which is easily counter balanced with $2 worth of thermal tape. You used it because you had to, because using aluminum would wear through the carb flanges.
D. That said, I congratulate you for making a good piece of hardware and doing so profitably. I only mention the above as corrections to what I think are exaggerations you've used in this thread to sell your filter. I give away my design, I've given away baseplates, and have been mailing folks here on ADV the templates, custom grommets (that secure metal to plastic firmly while isolating vibrations) and directions on how to make their own baseplates out to of aluminum. I have absolutely no commercial interest here. Take it for what you will.
Wow, you should probably start to make your own shit, after all, your jetting was contributed to someone's Baja bike. I bet those jets cost upward of $8.00 or so. Does your engineering degree cover aluminum and all it's thermal/wear/manufacturing properties too? It's funny how you make these public assumptions about this guys parts, have you ever owned one, or are you picking this all up from the internet? Or is it all because someone you know, knows someone who knows someone, whose brother in law bought a spark plug for a Bultaco once, and Rottweiler also bought a spark plug once, and, and, and........
For not having any commercial interest here, you seem pretty sure of yourself when burning down this man's product.
