- Also, when used in conjunction with the additional part TPP031 LP30, clutch work with a normal ratio of about 40% is actually alleviated. (. By installing VPC, clutch disconnection gets better.When you replace with LP30 lever push rod, it will be possible to reduce the amount of cut and close the position of the lever when the clutch is connected.).
- One of the less desirable byproducts of increased power is the need for a clutch spring upgrade, and the additional lever effort it requires. By adding the Variable Pressure Clutch (VPC) devise, clutch plate holding pressure is reduced at lower RPM’s, and increased as RPM rises, reducing the chance of clutch slippage as power builds. The VPC system reduces initial pressure.

AIM strongly recommend VP Performance Kits to upgrade '98 and later Harley-Davidson stock clutch for any performance engines, even a Screamin Eagle Stage 1 Kit (Exhaust pipe, Air cleaner, EFI tuner). Because as you know Harley-Davidson has reduced clutch lever effort from 2006 Big Twin model by reducing clutch spring pressure about 10%. Even though clutch performance is 10% less than before, the current engine size has been increase to 96ci. That means clutch performance may not be enough when you do any engine performance modifications.
VP Performance Kits are the best product to upgrade Harley-Davidson stock clutch and eliminate unnecessary heavy clutch pull (not like a regular heavy duty spring), but add up to 40% additional pressure to clutch as engine RPM increases (Centrifugal Force) to make very strong clutch clamping force. VP Performance Kit is including VP92T and Clutch spring.

Note: In the Chart, The clutch will not slip when there is your engine torque curve below the clutch pressure curve. These pressure and handling torque in the chart are calculated with stock primary and final gear ratio. These numbers will be change by primary and final gear ratio.

The Variable Pressure Clutch (VPC) by Tak's Performance Parts is not 'just a lock-up clutch'. The VPC is a system that reduces spring pressure at idle, and as the centrifugal force increases in line with rising engine rpm it provides the clutch with the required pressure to match engine torque. Adjust the clutch cable. Ensure free play of 1/8in or more at the clutch lever pivot between the clutch holder and lever without pulling ths cable. Install derby cover gasket (Parts#AIM003-003) and derby cover. Tighten bolts to 84-108in-lbs (9.5-12.2 Nm). Tech Note: You can use 18mm spark plug socket to.
