For more information, search the group site http://groups.Google.com/group/nighthawk_lovers?hl=en. for electrosport or alternator or regulator/rectifier. Note the response from Electrosport at the bottom.
There are ongoing discussions on the group, often by new members, regarding the low charging output at low RPM. Also a lot of questions about powering additional accessories: coolers, ray guns, sound systems, etc. I have related several times my improved alternator performance since switching out my regulator/rectifier from OEM to Electrosport. Like this one from 1/02/2009: Recent experience with my 84' CB650SC: Intermittent starting problems, sometimes after just riding and shutting down. Battery condition questionable. Charging system typical low output. I have a multi light voltage indicator from HarborFreight installed so I can see the voltage/battery/charge condition. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=46972 Replaced the battery with a new Honda/Yausa(?). Much better. Replaced the regulator/rectifier with one from Electrosport $100 http://www.electrosport.com/products/product-detail-581.php This made an enormous difference in charging voltage levels. Immediately after startup, when the (good condition) battery is slightly discharged, I get 12 to 13 volt. charging levels at 1200 RPM. At 2500-3000 RPM I will get up to 15 volts. After riding, the battery is at +13 volt., dropping to a fully charged 12.5 after turned off for a while. Am I recommending everyone change out their regulator/rectifier? No. If suspecting problems-or if you just want to know- put the Harbor Freight voltage indicator on your bike, temporarily at least. After determining your actual performance, then decide on the regulator/rectifier. Ride with full power, Hawkers! ----- Original Message ----- From: Info - ElectroSport To: Gene Henry Sent: Monday, April 18, 2011 5:17 PM Subject: Re: Honda Nighthawk '84 CB650SC Reg/Rectifier Hi Gene, The voltage readings your receiving off of our ESR210 is right where they should be. The rectifier side of our unit has upgraded diodes, front controlled rectifiers and the solder we use is rated at a much higher temperature than the OEM regulator/rectifier. The regulator cutoff voltage is also higher on our regulator circuit so if a customer has a healthy stator then they will see a voltage increase at the battery.

There are often discussions regarding the limitations of the electrical generation systems on the older Hondas '80 to '90. I experienced the same a year ago and replaced my regulator/rectifier with your # ESR210, and got a whole new system, beginning 12 v + at about 1200 RPM up to 15 v at 3000 RPM after starting discharge. Can other users expect this performance? The discussion is ongoing, and I would like to recommend your regulator/rectifier but would like to be sure my experience is not an anomaly. An email that I could post on the website would be appreciated. I guess my real question is: What kind of performance can a Nighthawk user expect if they change from OEM to your design regulator/rectifier. My experience was unexpectedly good.
