Sorry, if this is inappropriate here. Actually, I've been very thankful to this forum for providing the R125 Service Manual. I'm from India, and I ride an R15. I'm planning a 3000 mile trip to the highest motorable road in the world (Leh - Ladhak) and it would involve a lot of tough terrain riding through the Himalayan hills. I need to upgrade my headlamps before I can hit the road for this trip. Here in India, motorcycle with headlamps brighter than 35w are not road legal. I've had a dozen close calls with lazy cows, and agressive dogs cutting across the road. I have broken my right hand in one such occasion due to bad illumination. I was going through the service manual, and turns out, R125's stator assembly generates 200+ watts. That's enough for my R15 to decently run 55/60w headlamps. From the looks of it, even the circuit diagram looks the same: The rectifier/regulator unit seems to be a direct fit, but I'm not sure if the stator coil would be a direct fit on the R15. I found a guy on eBay who sells R125 stator for £39.99 Link: http://www.ebay.co.uk/itm/YAMAHA-YZ...UK_Motorcycle_Parts&hash=item3a6d7c8137#rpdId Since R125 don't sell in India, and R15 don't sell in most parts of the world, I understand that it becomes a little tricky to answer this question, but please share whatever you can: Can R125 stator assembly be directly mounted on R15 crankcase? Any replies would be appreciated!
