I will have Accelerator Modules available for the LC in two weeks time. The problem is a common one caused by lean mixtures prescribed by EU emission standards. The accelerator module improves the air/fuel ratio in the acceleration loop only and greatly improves the situation.

Does the AM not quicken throttle response?

Two aspects are important:
1. The on / off nature of the throttle
2. Usable revs and smooth takeup

1. EU regulated lean mixtures causes an on / off throttle response. In slow technical riding touching the throttle makes the bike jump forward, causing the rider to close the throttle, the need for power again makes the bike jump forward again, and so it goes, with the bike rocking to and fro - not good for technical situations. The AM smooths out this On / Off tendency. It also curbs the sensation of the bike "flooding" on opening the throttle wide at low rpm - a typical tendency of e.g. the KTM 690 or BMW F800GS.
2. The AM increases usable RPM, with more torque available at the lower end of the RPM range than before. On some bikes riders report an 1500rpm increase of usable rpm at the bottom end of the rev range.
BoosterPlug, LED Spots, Tool Tubes, RustStop, Kappa Screens, Top boxes, Tank Bags, ATG Gear - whatever works for me.
