in the middle of getting a 74 BMW R90S going again after sitting 30 years.
details here if anyone is interested http://www.advrider.com/forums/showthread.php?t=730033
BMW is equipped with a 240 watt alternator. which will not support heated winter liners without reducing current running loads. or upgrading to a higher output alternator $500+. would prefer to stay with stock alternator. if running load is reduced to 50 watt range then current charging system should support heated liners. which is 77 watt for heated jacket and 30 watt for heated gloves.
rear tail lights already switched to LED (1/2 watt low, 4 watt high) H-4 halogen 90/100 watt can be replaced with HID (35watt)
what's the best HID replacement for 74 BMW R90S motorcycle with H-4 halogen?
