V-Rod Camshaft Specifications
Special Notes on V-Rod cam specs
|
There is no accepted standard for measuring duration on
V-rod cams. The table provides the manufacturers lift at which duration was
measured. |
|
It can be very difficult to compare cams measured at
different durations. Even minor changes in lift can have a significant
impact on the duration. Grind profiles can vary greatly and provide major
differences in how fast the valve is lifted . |
|
Intake and Exhaust grinds are generally listed separately.
You can "mix and match" the various grinds to create your own
combination. |
|
Opening and closing degrees are generally not provided.
Durations are provided at the measured lift. By altering cam timing, you can
create your own specs based on the needs of your engine. |
