Yoshimura Japan releases TMS Air Funnel Kit for Kawasaki Z900RS and for Suzuki KATANA.
It is a setting tool and developed to create ideal torque curve by modifying air intake system.
As it is said a setting tool, further adjustment is possible with changing air funnel location by different length ones.
The tests at Yoshimura Japan were done without fuel injection resetting and working on this area should bring further results.
TMS abbreviation for "Torque Management System” and this idea comes from our racing development.
The TMS Air Funnel Kit for KATANA is delivered with 2 of each L20 and L60 Air funnels, and L60-L20-L20-L60 is the recommended setting fixed with Yoshimura exhaust system.
