Question about 1999 Yamaha TDM 850
When starting back fires sumtimes startes sumtimes not rectifier gets hot
Offhand, may I suggest that you have the battery externally fully charged. Thereafter start/run the bike with the voltage regulator (rectifier) disconnected. Shorted diodes or transistor inside the regulator maybe responsible for the abnormal heat buildup and likewise the backfire and/or the intermittent engine run. The CDI may be cutting out if the voltage is higher.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
