Billet Superflare EX650 Velocity Stacks

Boost the EX's upper mid and topend by 2-3 hp and lowend by 1-2 hp.
(as shown on the below chart)
and
improve low speed running and make throttle response crisper and more responsive
(not shown on chart)
and
give your EX a crisper, more solid intake sound at high rpm.
(hmmm..... is there a "grin factor" chart for that?  :-)

Our testing was done with:
stock engine, stock exhaust and stock air filter - and NO fuel injection tuning at all.
See dyno chart below.

Installs into the stock airbox  (with modified stack entry hole)-
The above picture shows the airbox lid removed, to show installation of stack.
 

Note:
The EX650 stack Installation requires a bit of extra work.
Grinding - Enlarging 
the original plastic airbox holes need to be 2mm larger in diameter.
Relatively easily done with a Dremel hand grinder or large rounded side of a file.

Most all of our other model stacks drop right into an unmodified airbox.

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.
