Hi, so here's my problem, I recently installed new indicators on my 1980 XS400G, everything is hooked up properly and works, except for one huge problem, the indicators wont flash. They just stay solid when ever I switch on either the left or right side. I have done some research and I think I...

After a year and only one effective start, I finally got something out of my xs360. It sounds like trash, and I need help. It takes many kicks to even get a response, and when it miraculously starts, it requires tons of throttle, has no response to it, Reba from 250 to 750 rpm, and it sounds...

Hey ya'll, So I'm in the process of restoring a 1977 XS360, this is my first project bike and so far I've found this forum to be extremely informative and I'm very grateful to have found it. I'll get straight to the topic here. Im having some trouble identifying which Mikuni carburetor...

Hi, I’m Grant and I got a 76 Xs360. It was my dads, and in 1989 was stored. In January of this year, I pulled it out and started work. In august, it ran just fine for the first time. However, it started sputtering and getting progressively harder to start and dies with throttle. Now it won’t...

Dear gentlemen, My XS400 has developed a serieus problem that has me completely at a loss. Driving 60mph my '84 Maxim would occasionally skip a few beats and continuing like nothing ever happend. The problem would only arise after doing a few miles at highish rpm. Sometimes it would lose a lot...

Hello everyone I got a hell of a deal on a 82 xs400 heritage special for 200$! It runs everything seems to work I just started tearing it down to build it but unfortunately I know absolutely nothing about this bike I have no manual or diagrams I am hoping all of you fine people could help me out...

The pickup coils are way out of spec on my 1983 XS400K and I am having a hard time finding OEM part numbers or aftermarket options, can anybody point me in the right direction?

As the title states, I'm desperately in need of a new TCI unit for my '83 XS400k. She's my only vehicle and I work 30 minutes away and the route takes me on a 70mph freeway for a large portion of the ride. I guess should tell you what symptoms I'm experiencing before I go off about how I've...

Hello all! I'm looking for a new kick start. Broke the clamp that the lever fit onto. Found one that fits an xs500, wondering if that will be compatible on my 77 400 model. The description lists model fitments, which doesn't include xs400, but thought somebody here may know if it would be...

Hi Everyone, I'm new to this site (actually to the whole "forum" thing entirely!) but I've been having trouble with my bike and would gladly take all the help I can get! So a little history: In a previous buy I got two yamaha xs400's (1977 and 1978 I think). The 77 had a title so I used that...

Hi guys, new member here, first bike I've ever owned. Bought this bike for $400 off craigslist about a month ago. It was running on one carb, so I took them out and gave them a thorough cleaning while replacing the float valves and needles. Put the carbs back in last week, fed them some gas...

I recently purchased a '77 XS400, it didn't come with a gas tank, what are my options? I know the stock square tanks are pretty hard to get so I don't really need one. I'm trying to keep it under $100+shipping. Thanks for any info

hey everyone ive been having a hard time locating anything on my mikuni carb for my 1984 xs400 seca. our goal is to tune it when we get it on the bike im looking for the idle screw but cant seem to locate it, and ive created this account to get help with it. but anything will help...

So first things first. I'm new to carburetors. I pulled the float bowls they're clean, but when I throttle to start the bike the floats, I think, they don't open with the butterfly valve. I can push them into the float bowl and they drop down at about the same speed more or less. Do they need...

Okay so about a week ago I bought my first yamaha... a xs360, I've had a few other bikes and am relatively familiar with the process of fixing them and within a week or two i'll be riding down the road. However, this story's a bit different. I can't get it to pop at all with the kick starter...

A guy who lives near me has an '81 XS400 Special II sitting in his barn. I don't think it's been used in a decade. It has a little over 5,000 original miles. A little surface rust is coming through the tank on the outside. The fork seals and tires are rotted out. Everything else is in decent...

I am trying to do an air box delete and I am looking for separate cone type filters but I can't find any. Anyone know where I can get some?

My 1977 xs400 needs throttle shaft seals to be replaced. Does that mean it needs a full carb rebuild? The previous owner said he "rebuilt the carb not too long ago." I'm guessing he either overlooked throttle shaft seals or used bad ones. What do y'all think?

so I know this isn't xs11.com but I've had a lot better input on here so I'm hoping for some luck. I bought this bike (79' xs1100 standard) and the guy I got it off really was doing some weird stuff with the wiring , I know it turns over and runs just fine by jumping it from the solenoid. I...

Hi, everyone. As the name states, I'm new to this forum and to motorcycles in general. Bought a 77 xs400 about a month ago and it started acting up once I brought it home. From what I've read, the symptoms seem to point to a vacuum leak (hard start, inconsistent idle that will often slow until...
