Hi Guys
I know there are a few threads on the Kawasaki kit cams but I haven't seen one on the Kent cams used in BSB??
I'm trying to understand how the Kent cams used in BSB work because there duration is shorter and so is the overlap compared to both stock and kit kawasaki cams.
Kent cam specs:
Intake Duration is 262.00 degrees.
Exhaust Duration is 258.00 degrees.
Inlet Cam Lift 11.20
Inlet Valve Lift 11.00
Exhaust Cam Lift 9.40
Exhaust Valve Lift 9.20
Installed Intake Centerline is 110.00 degrees ATDC.
Installed Exhaust Centerline is 110.00 degrees BTDC.
LSA is 110.0 degrees
Overlap is 40.00 degrees.
Kawasaki stock cams 2011-15 specs:
Intake Duration is 296.00 degrees.
Exhaust Duration is 293.00 degrees.
Inlet Valve Lift 10.30
Exhaust Valve Lift 9.10
Installed Intake Centerline is 112.00 degrees ATDC.
Installed Exhaust Centerline is 107.50 degrees BTDC.
LSA is 109.8 degrees
Overlap is 75.00 degrees.
Kawasaki kit cams 2011-15 specs:
Intake Duration is 301.00 degrees.
Exhaust Duration is 306.00 degrees.
Inlet Valve Lift 10.50
Exhaust Valve Lift 9.10
Installed Intake Centerline is 113.00 degrees ATDC.
Installed Exhaust Centerline is 108 degrees BTDC.
Kawasaki stock cams 2016-18 specs:
Intake Duration is 301.00 degrees.
Exhaust Duration is 306.00 degrees.
Installed Intake Centerline is 105.50 degrees ATDC.
Installed Exhaust Centerline is 104.00 degrees BTDC.
LSA is 104.8 degrees
Overlap is 94.00 degrees.
FW Developments D1660:
very vague info but I've been told
Inlet more duration (greater than 301) and lift (greater than 10.50) than the Kawasaki kit cam
Exhaust less duration (less than 293), same lift as stock (9.10) Kawasaki 2011-15 cam
