Not on my 750 twin. The horsepower peaks at about 7000 and redline is about 7500 so it already peaks right at the top. Bike makers are pretty good at squeezing all the power out of these engines.I've read where four wheeler owners retard the exhaust timing as a mod to extend the power toward mid and top. If you make clearance at the piston to allow for collision, would there be an extended power band?

VARYING LOBE SEPARATION ANGLE

Moves Torque to Lower RPM ***********Raise Torque to Higher RPM
Increases Maximum Torque ************Reduces Maximum Torque
Narrow Powerband *********************Broadens Power Band
Builds Higher Cylinder Pressure *******Reduce Maximum Cylinder Pressure
Increase Chance of Engine Knock *****Decrease Chance of Engine Knock
Increase Cranking Compression ******Decrease Cranking Compression
Increase Effective Compression *******Decrease Effective Compression
Idle Vacuum is Reduced ***************Idle Vacuum is Increased
Idle Quality Suffers **********************Idle Quality Improves
Open Valve-Overlap Increases *********Open Valve-Overlap Decreases
Closed Valve-Overlap Increases *******Closed Valve-Overlap Decreases
Natural EGR Effect Increases ***********Natural EGR Effect is Reduced
Decreases Piston-to-Valve Clearance **Increases Piston-to-Valve Clearance
LOBE SEPARATION ANGLE
Above 114 Deg. = Extremely Wide
114-112 Deg. = Wide
112-110 Deg. = Moderately Wide
110-108 Deg. = Moderate
108-106 Deg. = Moderately Tight
106-104 Deg. = Tight
Below 104 Deg. = Extremely Tight
ADVANCING / RETARDING CAM TIMING
ADVANCING **********************************RETARDING
Begins Intake Event Sooner *****************Delays Intake Event Closes Intake
Open Intake Valve Sooner *******************Keeps Intake Valve Open Later
Builds More Low-End Torque ****************Builds More High-End Power
Decrease Piston-Intake Valve Clearance ****Increase Piston-Intake Valve Clearance
Increase Piston-Exhaust Valve Clearance ***Decrease Piston-Exhaust Valve Clearance
Changing one and not the other causes varying degrees of things from both lists!!! :laugh: :laugh: :laugh:
Best of luck.
