5 ANGLE VALVE SEAT GRINDING (4 stroke) ............... $35 per seat

Reshape valve seats with the perfect configuration of 5 different angles to insure concentricity, improve valve sealing and increase air flow for maximum horsepower.

BRONZE COMPOSITE VALVE SEAT INSTALLATION .... $100 per seat

Remove OEM seats and install bronze composite valve seats found in many Factory heads.  Machine for optimum flow to provide more compatibility with titanium valves, prevent seat deterioration common with highly oxygenated fuels and dissipate heat more quickly resulting in a more reliable, cooler running engine (includes all seats needed for complete head).

BRONZE COMPOSITE VALVE GUIDE INSTALLATION ... $75 per guide

Remove OEM guides and install bronze composite valve guides found in Factory heads.  Size to valve to dissipate heat more quickly resulting in a more reliable, cooler running engine (includes all guides needed for complete head).

TRANSMISSION SUPER FINISHING.......................................$299

Debur and polish transmission and primary gears to a super finish.  This process is highest quality vibratory process involving abrasive media and chemicals that was designed by the military.  Superfinish eliminates much of the fiction between parts to lower the operating temperature and reduces drag to increase horsepower to the rear wheel.

VALVE TRAIN SUPER FINISHING...........................................$200

Debur and polish camshaft, rocker pins and valve buckets to a super finish.  This process is highest quality vibratory process involving abrasive media and chemicals that was designed by the military.  Superfinish eliminates much of the fiction between parts to lower the operating temperature and reduces drag to increase horsepower to the rear wheel.

CRANK TRUE & BALANCE ................................................... $275

True and dynamically balance crank to exact specifications for optimum performance and decreased vibration.

CASE MATCHING .................................................................... $80

Port intake tract, match cases to cylinder wall to decrease turbulence and maximize air flow.

CASE STUFFING (2 Stroke) ................................................ $175

Weld cases to reduce dead space.  Reshape areas of air travel to increase velocity and maximize air flow.

CARBURETOR BORING ............................................. from $65

Straight, step or taper bore carburator to improve air flow into a modified engine.

MACHINE FLYWHEEL ........................................................ $65

Precision machine flywheel for quicker rev.

*All prices above are labor only except for seat and guide installation.  Additional labor is required on some services to remove and install parts from the motorcycle or engine.  Worn parts will be additional as well.  EBR recommends race fuel in all modified engines.
