This is info from S&S: S&S Cycle Complete Gear Drive Camshaft 509G Cam Kit
• The S&S Camshaft Gear Drive Kit increases valve timing accuracy in 1999-2006 Twin Cam 88 engines by eliminating timing chain lash and the loosely fit stock cam gears
• This is accomplished by replacing the stock cam drive sprockets and chain with light press fit S&S gears
• Because the chain, chain guides, and tensioner are eliminated, there is no longer a possibility for these parts to fail and damage other parts
• The S&S Camshaft Gear Drive Kit reverses the rear cam's direction of rotation, providing additional operating clearance between cam lobes
• As a result, higher cam lifts are possible with the gear drive kit
I am wondering that with the lift of the cam, and rest of engine stock, the advance that the cam creates is it possible????? That cam advance is to cause power under load which would alleviate engine breaking on decel????
