Kit Oversized Exhaust Valves by Gabro Racing Team

Special Kit with Stainless Steel 27 mm Exhaust Valves (26 mm Standard)

Product Description

This kit solves the upper revs flat power curve in race motors: the more the engine can breath adding airbox, stacks, cams and all the usual add-ons, the more its power curve looks flat at top revs.
Cooking point is stock exhaust valves size: fitting those valves the un-choked engine will deliver an astonishing top end power.

The kit includes:

• 4x 27mm exhaust valves
  4x Specific super-finished springs.

Who This Product is For

It’s a race product, it needs a proper assembly and valve clearance check.
