Question about Yamaha Motorcycles

1 Answer

I have a 1990 yamaha RT 180 dirt bike. I bought an aftermarket headlight and would like to know the best source for supplying power to the light. I also bought a 12 volt battery in which I am running the light from. I would like to use the bikes generator as a means of recharging the battery. The bike has a low oil (2 stroke) switch which also acts as a neutral switch. It is 12 volts. I was looking on line for a diagram but had no luck

SOURCE: Bike won't start, battery bulged

Chances are it is the rectifier/regulator which is a sealed unit that has to be replaced if faulty. A bad one can cook your battery as well as your light bulbs and wiring. To check this connect a VOM across your battery terminals while the bike is running. If normal you should see about 13.5 volts. If your voltage climbs up to the 18 to 22 volt range or higher you must replace the part before you do further damage. Also be aware of the dangers of over charging a battery as it can explode and cause personal injury. If your battery has been cooked you will have smelled sulfuric acid and the battery will become hot to the touch. If that is the case you will also have to replace the battery as well as it will no longer hold a charge. When this happens the battery will bulge and this is called plate bow. By replacing both the battery and the rectifier/regulator you should be as good as new. In very rare instances it could be the stator which could cost a lot more but chances are its just the rectifier/regulator. I've seen them for very cheap prices on Ebay.

SOURCE: Honda CRF 230 dirt bike will not even begin to crank

Check for a good ground from motor to frame and from frame to battery. And if battery is more than 1 - 2 years old (on a dirt bike) replace battery with a known good one. - if this does not fix it check the start switch for dirt and corrosion

Maybe the voltage rectifier has gone bad. I would try getting a new one.

SOURCE: i bought dirt bike for husband! is 2005 yamaha

Congrats on the purchase! easy way to tell look at the exhaust pipe. if it is just a thin tube that is tight to the engine and goes right to the muffler it is a 4 stroke (250f). the four strokes have a square-ish head. Deep/bass-y engine sound. If you have a large (probably black) exhaust pipe with a large bulge in it (5-6" diameter) that wraps around the front of the frame, its a 2-stroke. They have a more round cylinder head. Beautiful pingy sound and a little smokey at start up. DON'T FORGET TO MIX YOUR GAS!!! there should be a serial number sticker at the very front of the frame (behind the number plate where your triple clamp/handlebars connect) Probably on the left side. Hope it helps! rate please :)
