The piston rings were replaced about 3000 kilometers ago (~1860 miles) so I guess they shouldn't be the problem. I will check for compression.

I've also replaced the condenser (all the replacements are from the Yambits website) but I still have the same problem. Also, there is a little oil on the spark plugs. Can it be a carburetor problem or something more serious?

I was thinking the same, I have the original condenser so I am sure it may cause some issues.

Hello everyone, I own a 1980 Yamaha XS400SE. I've been experiencing a strange issue with it lately. The problem started with the bike running normally, but after warming up (about 20-30 minutes of riding), the right cylinder stalls. I replaced the ignition coils and contact breakers, and now I...

Hello, In the last two short trips I've had a problem with missfire on my right cylinder. The bike starts but has problems for about 15 secs. I can't figure out is it better with full choke or half on hot weather. Anyways, i drive it in half choke for some time so it warms up nicely. After it is...

So the only thing i can do is buy an replacement from ebay i guess..

Hi there, I've already created an thread some time ago about my problem with the regulator and rectifier. An electrician checked them and turns out that the regulator (i guess that's what it is, the 3 pin one) is not working propertly. As I live in Macedonia, shipping costs for a new replacement...

Okay, Ill ask the previous owner for help. I really don't understand how they work. Thanks for the suggestions and help. I will write updates.

Well as you can see in the pictures I sent, white is not connected to anything on the motorcycle. That's how I got it from the guy that had no problems. I rebuilt the starter and had an shortage while starting the bike. Something smoked out. That's why I think that's the problem.

Well yes, i think its best to buy a new one.

I found an topic on the forum. There was an post that said that regulator and rectifier should have good grounding, that's why the housing of regulator and rectifier are connected both to the frame of the motorcycle. Also, i performed the tests while they were disconnected as stated in the manual.

By looking into the manual, this regulator replaces the original one.

I don't know, the previous owner drove it like this and had no problems. He went on 2000km ride. I really dont know any harness wiring, thats why i ask for easy alternative with new part.

I tried the regulator checked as said in the manual. With disconnecting it from the connector, i couldn't get any reading when i place 1 pole on black lead wire, and the other pole on the casing of it. I had an wire explosion a few months back, thats when the problem started. I think it's just...

Ill take better pictures, with the connections and all and post them here.

I don't know. Why would it have 2 things if one is combo. It's my first bike, i don't really know how things work.

I have these two. Can you tell me how they are called and what are their purpose. I am currently charging my battery to full charge, then i will perform tests and write the results. On a lower charge i got 13V at 3000RPM. I don't know if that's fine or not.

Hi, I have XS400 Special 1980. I bought a new battery and after 2-3 days of riding, battery dies, the starter doesn't have enough power to spin and after some time it completely stops. I think it is because of the regulator. It is the original one as far as i know. However, shipping from ebay to...
