Website yg penuh info pasal camshaft
More duration - Power band moved higher in rpm range
Less duration- Increase low-end torque
More Overlap - Improved signal to carburetor, lower fuel efficiency
Less Overlap- Improved low-rpm responsiveness, better fuel efficiency
*Effective Lifting 1/3 of valve diameter [A Graham Bell]
*Maximise cylinder filling for lifting = 37%-40% of valve diameter
*Standard 135lc cam intake lift 30% = 4.57 mm lift , exhaust 37% = 4.923mm lift
*Best cam profile: quick opening and closing rate (high acceleration and high lift), moderate duration and overlap. this type of cam will give pickup top end power with less sacrificing of mid range power.
