Question about 1992 Yamaha FZR 600
Every time I put the positive wire to the battery, my regulator start smoking, the bike is running fine it's just start smoking
Common problem with poor quality parts, the regulator is the problem, the generator is working other wise you would not have fried the wiring, you answered your own question. someone telling porkies to get more money from unsuspecting client?
The regulator controls the voltage not the generator, the generator only supplys the voltage it cannot overcharge unless the regulator is not working properly, simple!

your voltage/reg. can be tested in a couple different ways check ground res. check res. then revs. bias on diodes you have ac in dc out it sounds like you may have a diode gone bad allowing ac curent to flow causing the wires to get hot

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.

i had a similar problem on my 1998 honda superhawk. I was down in Daytona Beach, Florida, and it was really hot and my battery went dead. It turned out that the heat of being down there along with the frequent short trips and idling we were doing down there fried my regulator/rectifier. It actually melted it was so hot. I bought a new regulator rectifier from a guy online who was really cool about it. Rick's Motorsports Electrics was the name of his store.
I looked up the part for you. check it out: http://www.ricksmotorsportelectrics.com/proddetail.php?prod=10-417&pmc=OTRZYW1GWlI2MDA=

If you're going through regulators that often I would suggest going after the stator. Make sure it's not grounding out on the chassis. Find the 3 yellow or white wires that are connected to the regulator. using a meter in OHMS ( looks like the horseshoe ) with the bike off check wire one (red ) to wire 2 ( black ) then wire one ( red ) to 3 (black ), then 2 (red ) to 1 ( black ) and 2 ( red ) to 3 ( black ) , then pick one ( red ) and black to the chassis, motor, ground. somewhere metal on the bike. The first series of tests you should get some sort of numbers, ( which should be somewhat close in numbers ) When you go to ground, Chassis you should get no numbers, OFL, OL, or the horseshoe sign if you get numbers there, the stator is bad and your transmitting ac voltage to the chassis.
