    F650ST Warning warning: New regulator from Motorworks Fitted the new ODYSSEY battery and new regulator, -The instructions say to fit the power output of the regulator directly to the battery. Looking at the HAYNES wiring diagram, this moves the power in from the regulator to the other side of...

    Anybody familiar with the regulator requirements for the F650ST? I have measured the charging voltage at 4000 rpm, at 14.7 volts with the lights all on, and about 16.5 volts lights off. I think it should be a steady 14.7volts and the regulator might be dodgy. Any recommendations here? I...

    Hello, There is a voltage regulator made in Greece. Those people from there say : According to the widely adopted design of similar products, the alternator works always in full power so the engine has always the load of the full powered alternator. The regulator rectifier we manufacture...

    Hello everybody, I had problems with my voltage regulator. The voltage on the battery was over 15,5 volts with the lights on. I bought this voltage regulator made by a Greek company. They say they built if differently so that it doesn't get hot: After many years of developement, the...

    Just popped round the block to see if we had cured the terrible mis-fire by changing the coils plus stripping and cleaning the carbs. A big fat no. Just popped the seat and happened to put my hand on the Voltage reg, hot enough to burn i'd say. Checked the connections to it and the plug with...

    Hi all, I have just changed my voltage regulator and has solved my '95 Funduro running/charging issues, hurrah! I have seen the mods for relocating the VR to a non under-the-seat position. As I'm a bit of a PC geek, I had a different idea. I had an odd motherboard copper heatsink lying...

    Hi, I have a 98 F650st. It has recently been very difficult to start, when it does it refuses to rev over 3000rpm, on the few occasions I have got it to run almost normal, I can see the battery bubbling away. It will rev a little better when the cooling fan is on. In my limited experienceI think...

    Prologue: After a year in my garden (was travelling), I had to install a new battery to get my F650 GS working. Fine. Chapter One: My battery was bleeding off acid, and the damn leed came off and ruined the paint. The bike would randomly stall at lights randomly, and she eventually stalled...

    After a lot of research on the net have decided that this RR might be the best solution to our woes: http://www.shindengen.com/resources/content/1/1/1/1/documents/FH012%20Data.pdf Rated at 50 amps, this should handle the power from the F650 stator easily. This is a FET unit unlike the normal...

    Hi all I renewed my regulator not so long ago but I am very curious about how many ST and Funduro owners had to renew their regulators once or even more and with what sort of mileage on it. I want to know if even without changes that the regulator keeps failing due to the heat below the saddle...
