I....It doesnt gharge below 2000 rpm.

That is a problem. In fact, at idle your bike could actually be producing more voltage than say at 3000rpm. This is because below a certain rpm, the voltage regulator is bypassed (per the service manual) and the voltage comes directly from the rectifier. That concept sounded strange to me but I tested it on my 2000 busa and at idle, the charging voltage was ~14.3. When I reved the bike, the regulator kicked in and the charging voltage went down to ~13.7. If you're not getting any charging voltage below 2000 rpm, something isn't right.

If you don't already have a Battery Tender, I STRONGLY recommend (IMNSHO!) that you look closely at the BatteryMINDer.

Amazon.com: BatteryMINDer Charger/Maintainer/Desulfator - 1.3 Amp, 12 Volt, Model# 12117: Automotive

The basic concept was developed by a friend of mine for the Army to condition batteries in the M1A1 tank. He was formerly Chief Scientist for Exide battery. This uses an electronic pulse technology that can reverse the formation of sulfate crystals in lead acid batteries. It also has electronic sensing to form the proper pulses and to stop charging at the proper level. I have had used my BatteryMINDer to rescue many old batteries and would say it has paid for itself ten times over.

Thanks MVANSOMEREN. I been trying to find this information for years. + 1
