Not to throw gas on the fire, but the Buell 1125 badweatherbikers.com forum has hundreds of pages of discussion on shunt vs series voltage regulators. Comments span a cross section from very knowledgeable electrical engineers to bush ignorant traditionalists. Overheating and resulting stator or regulator failure are problems with Rotax engine Buell, BMW, Aprilia and many Ducatis and Japanese bikes. A 2016 or 2017 Consumer Reports article notes that about 30% of modern motorcycles have charging system faults. As other forum members have noted, inadequate/faulty grounds, exposure to water, vibration, heat, lack of heatsinks or ventilation can all cause problems. I switched the Ducati-labeled shunt-type V/R on my 1125 to a Shindegen 847 series type rated for 50amps. The Shindegen 775 series type is rated for 27 amps and is good for bikes with a max 9000 rpm. My 847 never gets more than warm, even though it is mounted in the same location the OEM V/R was in. I will be installing a 775 in my 2001 Rosso Mandello soonest. The problems caused by the Ducati-labeled V/R, and the inept electrical Band-Aid which H-D offered in an attempt to solve the problem are legendary. H-D had to replace a lot of heat-damaged stators, rotors, and V/Rs during the warranty period, and those of us who arrived late to the party had to shell out for our own solutions, once the flaws in the H-D Band-Aid became known. Jack at roadstercycle.com has a lot of experience and expertise dealing with motorcycle charging systems. He offers lots of options and quality wiring kits at decent prices. I am not affiliated with Jack or roadstercycle.com in any way.

Hello Pete. I'm a new owner of a 2001 Rosso Mandello and would like to install one of your sump plates. If you still make them, please let me know how to order, pay for, and ship one to the USA. Regards, Araignee
