* !! NOTE !! (THIS CAM MUST BE USED WITH STOCK HONDA VALVES) OR AT LEAST CHECK TO MAKE SURE THE AFTERMARKET VALVES CLEAR EACH OTHER WHEN THEY PASS EACH OTHER... (YOU CAN GRIND OFF SOME OF THE VALVE'S OUTTER OD SO THEY DO CLEAR IF NEEDED)

SETTING THE VALVE CLEARANCE AT .003" WILL HELP WITH THE VALVE CLEARANCE IF YOUR USING AFTERMARKET VALVES

THIS IS AS BIG OF CAM AS WILL FIT IN THE OLD TYPE HEADS

IT HAS SOME LIFT OVER THE STOCK CAM, BUT TONS OF DURATION

*

THIS IS THE MOST RADICAL CAM MADE FOR THE OLD TYPE HONDA HEADS

*

THIS CAM HAS 6MM OF LIFT.

Camshaft Calculations - Lobe Center / Duration AT .050" VALVE LASH

THE VALVE LASH IS MORE FOR CARS AND REALLY DON'T GIVE A

TRUE CYCLE READING,, BUT THATS JUST HOW IT'S DONE.

THE LASH IS ONLY .0025" ON THE BIKES COMPAIRED TO .050" ???

THIS CAM has an Overlap of 40.00 degrees and has an

Intake Duration of 255.00 degrees. The Exhaust Duration is

265.00 degrees. The Inlet Cam has an Installed Centerline

of 102.50 degrees ATDC. The exhaust cam has an Installed

Centerline of 117.50 degrees BTDC.

LIFT IS 6MM
