    The Banshee yfz 350 carb recal kit was designed with as much care and attention to detail as we give to our EC997 dynamometer and test routines, our Shift STAR shift improvement kits, our Billet Engine Covers and all of the other products that the quickest road racers in the USA and World used to collect a total of 9 WERA and F-USA national Championships - along with the Suzuki Cup World Champion, Rob Jensen.

    We've now entered the off-road arena to bring some new, exciting, well proven concepts, such as our easily tuneable "HDJ" style jet kits and several other things that we've picked up along the way.

    One of the improvements was dyne systems design and test routine design - We have been saying for years that inertia dynos were misleading and now, these new "HDJ" carb kits show how much better the EC997 load dynos are than inertia dynos when it comes to developing any performance products. Sounds a bit egotistical? Perhaps it sounds that way - but, I think that we've got quite a few local Norcal racers that we've done fine tuning work for that would agree with us.

    We really aren't egotists -  We are just passionate about fine tuning.

   The Factory Pro HDJ kits, designed by Marc Salvisberg, will run more evenly over a wider temperature and altitude range than any other carb kit and will produce 3% to 8% better power than another carb with the "best main jet" in it, when properly tuned and tested under a real load. This does not mean an inertia dyno - though, power will be better with a dealership level dyno, also.

So - Here's the power - Buy it!

Thanks!

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
