EVO Shift Star and Shift Improvement kits

SHFT-PRO-HON-1  $139.95
(includes microbearing detent arm, F-Pro spring and clutch gasket)

Pro Shift kit -

Make shifting quicker and virtually eliminate missed shifts. Helps address missed shifts caused by poor shift detent "star" profile.
Note- This kit will NOT fix rounded gear engagement dogs! It will help damage NOT occur to good gears caused by missing shifts.
The same kit that most AMA teams used "back in the day".

It's budget priced, effective and requires somewhat more foot pressure to shift and is not quite as quick shifting as the Shift STAR kit..

Requires clutch assembly removal - including complete clutch basket's big nut. An air or electric impact wrench is "the way" to go.
A shop would bill 2-2.5 hours.

A great time to do this is when you are replacing clutch plates as you are "right there".

Hi Marc,

Shift Pro worked like a charm on the first bike.  3 day event and never missed a gear all weekend.  VERY impressed.  Even won a race.
BUT
Can you chase up the 2nd one I'd ordered as I want to get the wet bike running?

Cheers

Float bowl vents must be vented into the airbox with modified airbox - and probably should be with a stock airbox, too.

Still needed to advance the intake cam, but couldn't at the time. Estimated power would have been 56-57 if.......

Northern California's most unforgettable flying experience.  No experience required.  Open weekends!

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.
