Shift STAR

(star, arm and spring kit)

Make shifting MUCH quicker and virtually eliminate missed shifts. Helps address missed shifts caused by poor shift detent "star" profile. MUCH more consistent shifting!

Note! The H21 kit does not include a gasket for the F4i - You will need to supply your own clutch cover gasket.

Billet LH Engine Cover
(fitment verified by AHM)

LH $279.95\


Left Side Cover WITH Integral Slider! (patented!)
For race or street use. Absolutely the strongest cover you can buy. Highest strength / weight ratio available.
More clearance AND cover thickness than stock LH side covers.
For protection: When the stock left engine cover breaks, the rotor smacks the ground and bends the crankshaft - which destroys the engine cases. Totaled.
Can be show polished to a mirror finish.
Includes: Cover, frame slider, gasket  and replacement stainless steel allen screws.

Beveled for more cornering clearance - directly traceable to the  "Nicky" angle!

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.
