maintenance

Hey all, I have a very small leak on my left side header since I got the bike. I bought a non copper set of gaskets from Mikes that didn't work then I tried copper rings that came with the xs400 gasket set on ebay. I have also changed the header pipes. Still have a small leak. I'm starting...

So I've discovered that the bolt holding down my tank, near the seat, isn't a Hex bolt, but actually a hollow thread bolt. I'm guessing it's reverse threading. Not sure if any of you have run into this, or if the previous owner replaced the original bolt with this for some reason. Any...

A few weeks ago I got home and notice a squeaking noise at idle. Before I could get off and take off my helmet it stopped. This has continued to happen after a ride of a few miles. Yesterday, when I came in, it continued long enough for me to decide that it sounds like it's coming from an...

I just got a 1982 Heritage Special and I found a fracture at the top of the right headline under the collar at the engine. Is that a concern? Also if I wanted/needed new head pipes would sohc 650 pipes fit? Thanks, Wyatt

There is a knocking/tapping when my engine is running which sounds like it is coming from the underside of the tank, you can hear it in this video. Just wondered if this is normal for these bikes? Thanks, Sam. :bike:

Hey everyone! I have removed my exhaust system on my '81 XS400 in order to clean it and wrap it. Unfortunately, one of the flanges was so full of corrosion that it broke in two pieces :banghead: . After having done a lot of research on the internet, I have not been able to find a replacement...

I'm going over all the parts that I have removed from my XS360 and I noticed that the oil cover/filter bolt does not contain the piston, spring, or pin. I assume these parts form a one-way valve for oil to travel through the filter. No way to know when the PO lost the parts or how long it...

Hello all, After lurking the forum for a few weeks while researching bikes, I was able to pick up a beautiful XS400G for $950. The guy who sold it to me rode it for 10 years and his father owned it before him. Its got about 16,000 miles on it but looks great and rides well once shes...

Hey all. I've been riding my XS for about a month and a half this season and have loved it :bike: . At the start of the season, I modified my bike to accept Emgo pod filters on my intake runners and modified my jets to 142.5 main on the left and 145 main on the right. The jet set up worked, but...

My right cylinder is firing, and getting fuel, but not running... So I pulled the stator cover to check time. All the oil ran out of the bike when I pulled it off. I have searched and read thread after thread and half of them say, this is normal, the xs stator runs in oil. While the other half...

To my dismay, I discovered this evening that my front brake piston is leaking. I rebuilt the caliper a couple months ago and haven't been able to ride yet, but it looks like I get to rebuild again. Parts n' More lists a front piston compatible with 77-79 XSs, but mine's an 81. Further, the part...

I am trying to get an inline fuel filter... Is there a tangible difference between one from Mikes's (https://www.mikesxs.net/product/20-0013.html), $2.10 and K&N's (http://www.knfilters.ca/search/product.aspx?prod=81-0221), $9.99? Or is there a better option out there? Thanks.

Does anyone happen to know the torque spec for carb boots? I just got new ones to replace the ruinously cracked ones on my bike, but I can't find a spec anywhere. Neither of the shop manuals I have list it, and I've dug around the archive here without success. Also, do I have to do anything...

Away from my bike at the moment, I have a 1983 maxim 400. Anyone know the stock healight width? Or where to get chrome gauges? Thanks guys! Guessing the width is 7 and a quarter, but not sure. Looking to replace and I need to know width if someone knows it :) thanks!!

guys, I was doing the yearly check on my XS400se and hit the wall when it came to inlet valves clearance check - I couldn't remove the caps covering the regulation screws. After using some not-very-smart-but-effective tools I managed to actually loosen them, but... I had the same issue last...

Hi, I'm newly the owner of a 1980 XS400 and brand new to this forum (obviously). I've been lurking for a couple of weeks and your various links to manuals and tech advice has already proven helpful. Now I have a specific question: are there differences in thread pitch or diameter for the oilpan...

I have been searching for different pistons to replace the almost obsolete xs400 pistons. After looking through a lot of part diagrams I stumbled on these guys. KAWASAKI KLF250 Bayou 03-11 Piston They look very similar to the xs400 OE pistons, but run a slightly lower compression height...

Hello all! I have met some of you and you have already been such a huge help in the past. Now this is a thread dedicated to the journey of my 'new' bike affectionately dubbed Scarlett. I picked this bike up in Oct 2013, the PO was moving so he needed to unload it. When it got it, it was running...

There was a thread about syncing carbs I remembered seeing yet when search for it I can't find it anyone have a link or can explain exactly how to do it?:confused:

does anyone know of any online owner manuals as I have purchased a 1982 xs400 and some things are worn on the bike like the fuel valve I don't know where the valve should be kept turned too on the bike for on off and reserve tank
