Actually with the Jap bike you gotta be concerned with marketability if that is
your goal.....how many bikes are still out there and how many customers if you
advertise widely can you get to buy your product?    

as to making something like this relatively generic,       well I suspect bikes
are alot like cars in this respect......and the attendant air
cleaner/pipes/manifold problems are not any less....you need VOLUME 
here....fine if your Honda/Yam/Harley....but you are trying to do all 3 or
so....and with a very limited production volume...

I been there, did DPFI on my old Pontiac 455 engine....took an act of GOD....NOT
a marketable thingy...just an engineering excercise on my part...GENE
