    Small spring found in oil change

    Just picked up an 1980 xs as a parts bike for a chopper build. Engine runs fine but I needed to remove it to prep the frame for a hard tail. When I was draining the engine oil there was this small spring magnetized to the drain plug. I haven’t done a whole lot of engine work on these bikes and...

    XSJohn's right side hotter theory - explored

    In another thread on this site XSJohn mentioned something that would lower cylinder temps by 20+ degrees. I am REALLY interested in finding out exactly what John was talking about here, so I did some digging. XSJohn's comments are in blue for clarity. This is a start, but there has to more...

    Fork identification & rebuild help

    Hello, I have a set of forks I'm trying to rebuild and I've got a bit of a quandary. I purchased this set of forks with my XS650 under the assumption that they were XS650 forks but that does not appear to be the case! 5twins suggested in another thread that they may be from an XS500 given that...

    limping with stock forks - or worth the rebuild?

    Hello folks, I've got me heart set on a nice set of TCBros front springer forks. the construction looks super solid from their video, and they come with lots of support in terms of calipers, bar mounts, and all that rigamarole. the trouble is, with all this corona quarantine happening i am...

    John's Oil cooler questions

    I saw Johns post regarding adding an oil cooler from the larger displacement Yamaha's of the day to the 650, and I've been absolutely determined to do the same to my bike so I can take it all over the states and possibly down through Mexico with less chance of breaking down during long rides...

    Heiden Sump Filter- Reviews?

    I removed my sump filter last night to find the classic torn mesh on what appears to be the original filter. After doing some forum research, it looks like the MikesXS filters seem to work, but really aren't any more durable that the OEM ones that have been repaired with JB weld, sheet metal...

    Aluminum shavings in the oil

    I have just finished restoring an ’83 Heritage Special which had not been ridden since late ’05 and only has 6800 original miles. When I started the project I changed the oil and did not notice any shavings, but that oil was very dirty and I might just have not noticed any. After getting it...

    RH cover leak

    I had to fish for the tach drive washer on my ‘76 650C so I took the RH cover off. Fished it, out everything back together (save the kickstart), then discovered I tore my old gasket so it started to leak. Looked like the original so I decided it’s time to replace. Chipped off the old gasket...

    What's this noise coming from my engine? (video)

    So my bike fell over not too long ago and before it did it did not make this noise. Before it fell the timing chain was tensioned correctly and valve clearances were in spec. I've just recently re adjusted the cam chain tension, but haven't adjusted valve clearances yet. I don't see why they...

    Oil Filter Suggestions/Questions

    Okay so I drained the oil in my 1980 xs650 for the first time and found the usual gunk and tiny bits of metal that seems somewhat normal from what I have read on this thread. I drained the oil out and took both filters out and they look like they are in pretty bad shape. Here is some pictures...

    Does this mean I need to take apart my engine?

    I know this obviously means something is wearing in the engine. Is there a way to find what's wearing out without tearing into the engine? Could it be a piston? Is it pointless to ask what it could be and better to just start digging in until I find something? Also is this why the bike would be...

    What oil do you use and why?

    Now that it's getting hot again I was wondering what everybody out there in XS Land uses during the summer months. I have about 75 miles on a fresh top end using rotella 15w40 and I'm thinking I want to switch to something heavier for the heat and to maybe quiet down the top end a little. thanks!
