Variatorfjäderset Naraku

The current version of the Naraku counter pressure spring uses a modified alloy spring providing better resilience and above average strength
Replacing the spring is necessary when tuning engines
Prevent the initial response from the variator therefore increasing the engine speed
Delayed engagement will increase the power at pull off
Markings on the spring help you identify the strength of the spring
