I'm not up on the current bikes, so look for some specifications on your particular bike. I expect you have the 2K3 flywheel/stator which puts out about 70 watts. The smaller 2K2 puts out about 35 watts.
The 2K3 will handle a dual sport kit, the 2K2 will be marginal. An estart bike has the 2K3 with a half wave rectifier and battery. It will be a split system with some DC output for battery charging and AC output for lighting. I believe a non-estart bike only has a voltage regulator and AC output for lighting.
