NEW FROM BIG DOG MOTORCYCLE COMPANY............

- Kits are designed to simplify high-lift cam installation and increase spring force to reduce the risk of valve float
- Eliminates most of the complicated procedures and specialized tools required to prepare cylinder heads for high lift cams
- Sidewinder springs can offer high RPM capability with less spring pressure because they do not add as much mass to the valve train as multi-coil spring packs. Less mass means that the
- valve train does not take as much of a beating at high RPM, since the valve springs do not have to exert as much force in order to control the valves. Lower spring force results in reduced
- valve train noise, increased valve stability and longer valve train component life
Kit contains 4 valve springs with 4 top collars, 4 bottom collars, 8 valve keepers and 8 valve spring shims (4 each of .015 and .030)
Specifications: .585 lift, 1.800 installed height, 125 lb seat force, 332 lb force at max lift and 6500 max RPM

Chevrolet at Geneva
Mon, 10 Mar 2008By Guy Bird Motor Shows 10 March 2008 11:31 What’s new on Chevrolet’s Geneva Motor Show stand? There were more exciting show stands at Geneva but Chevy did muster up a small – in every sense – global unveil in the shape of the three-door Aveo supermini (the five-door was unveiled last autumn at the 2007 Frankfurt show). The smart-ish new exterior – all big grille and wraparound front lights – is a big improvement on the mundane Kalos it replaces but still a bit of a let down.
