frame

Grabbed a 1978 xs400 2e - Kick start only in okay shape. Been cleaning the carbs, new oil, battery etc. When taking a look at the frame I noticed this dent. Could this be the end of this bike - as in not safe to ride any more? Pretty bummed out and looking forward to any feedback. Perhaps it...

Pic included, looking to buy or find a cap for this side of my frame.

I'd like to use the "Saddlemen Eliminator" tail section and seat for my '81 build and was wondering if anyone has used this seat on theirs before. I need to figure out if the seat frame hoop I'm looking at will work. What size seat frame hoops are you all using for cafe/brat builds?

After hours of painstaking swing arm bolt removal I noticed I may have damaged the inner side of the bolt hole on the frame. This was probably due to me being an idiot and slamming a bolt that didn't fit properly in the hole in attempt to remove the swing arm. (I also had to grind out the swing...

Hi Guys, I just started my first 1980 xs400 build and have been looking to try and find a 3d model so I can work on my design, fitment for custom fabricated parts etc etc. I tried to scour all the typical CAD sites but I can't find anything so I was wondering if one of you guys might have one...

So on the left hand side of the frame, below the engine, I found what appears to be an odd bulge in the frame. Any idea if it is normal for there to be a bulge in the frame there? That would be the spot in question. Doesn't seem right to me. Figured I would check with you guys about it...

Does anybody know if there is any difference between a 77 and 80 xs 400 frame? I know the bikes were a bit different but I feel like the frame hasn't changed inbetween those years. How often does a bike frame actually change right? I wouldn't be surprised if the sportster frame is the same as...

The side-cover on the right side of my 1984 xs400 has had the grommet holding the batter cover on disintegrate. I've looked around unsuccessfully to find a replacement. I'm hoping someone here has run into the same problem and has a source.

Hallo there I had this wonderful idea of converting the mechanical cable type to a digital electronic output, to work with any electrical cauge. :wtf: So since i'm no genius with motherboards or whatever you need to make a conversion , i need your guys help. :shrug: I have three ideas...

Model: 1980 XS400 Special (XS400SG) I am in need of a lift or some kind of solution to getting it up off the ground so I can remove both the wheels so I can replace the tires as well as do a complete tear down of the entire motorcycle for restoration, repainting, and then reassembly. The...

Hello, I'm looking into dime city's 2.5" tachometers, the question is they offer two ratio settings, a 1.5ratio and a 1.7 ratio. Can anyone tell me what ratio would work with my 81 xs400 special II Yamaha? Thanks.

What do you guys think, would the more squared tank fit on the 1981 400se? I have the xs400se with the stock tank, but i kinda like how the older tank lines up with the frame. Gives it a nicer look in my opinion. 1981 Yamaha xs400se 1977-1978 Yamaha xs400 Sorry for repost, if...

The bike is a mostly stock '81 XS400-SH with 7500 miles (had it since 1900 miles around 6 years ago. It's fairly beat-up, but been a solid bike for getting around for several years now. It runs just fine. I use it frequently now because getting parking on campus in the daytime is impossible...

Hello I have a 79 xs400 and I wanted to put a voodoo vintage ridged frame on it. To keep the cost low I wanted to use the factory rims. Will this work with the new rear frame section or will I have to find new rims?

Hello I've got a 1980 xs400 special 2. I was noticing a grinding noise and determined it was coming from the chain. Upon inspection I noticed that as the tire rotated everything would be normal until it would hit a spot where the chain tightens up. For now I have the tension set at the tightest...

Hi all, So I've ripped apart my maxim to convert it into a café racer. Is there a gas tank that would work with my frame? The stock tank isn't really a café racer type. Im thinking cb500 tank? any thoughts?

Has anyone ever faked a hard tail by welding and undercarriage in for say an Ironhead 1000? I imagine if I can think of it, someone has tried, hell maybe here many have and are well known to some of you? I like the idea a lot and I have a title'd frame for the project. I'm a dirt farmer and...
