Suzuki GSX-R 600 K4 Dyno Graph

Before and after for a 2004 gsxr600 suzuki.

This engine competed in club events during 2005. Due to the well known problem of the titanium valves failing in stock k4 engines, we replaced these with aftermarket ones. These have proved reliable well beyond 1,000 hard race miles whereas the titanium ones would crack at anything up to 100 miles and cost £800 to replace! This spec of engine is good for a season of club racing without any expensive maintenance and includes:- Kit ecu, kit loom, kent cams, gasflowed head, raised compression, blueprinted, powercommander, yoshimura full system. Notice how long the engine holds peak power. Extremely useable and very torquey.
