I have a 84' Fj Yamaha that had a 4 cylinder that ate a valve. My friend installed a Xs 650 engine. I rode it for a summer but it needed better engine mounts. He used aluminum plates instead of steel. I parked it awhile with the idea I would square it away. But... as with many projects I won't get to it anytime soon. It's been at a friends garage since... he broke a turn signal move'n it around.
$650.oo.... firm. If I could figure out how to post photos here I would... Or, PM and we can try that approach. Bike is in the north burbs of Minneapolis. Thanks

gggGary: XS650.com LOL Feb 16, 2017 20:49:02 GMT -5

buell88: Anybody have any idea who built the xs650 tracker used in the Draggin Jeans Ad on Pipeburn? May 16, 2017 16:24:09 GMT -5

joshua: The regulator/rectifier unit I got from Mikes PMA has closer hole spacing than original. Are we supposed to mill the holes to fit? Jun 7, 2017 19:25:58 GMT -5

joshua: My bad. I found the bracket they supplied to mount the rectifier/regulator... Uh oh. How is this meant to work? Which way is it meant to mount? Looks like I have to use some spacers or something. Good instructions would be nice. Jun 7, 2017 22:09:52 GMT -5

craig8johnson: Not sure if this is the right spot or not but oh well... Jul 11, 2017 18:04:15 GMT -5

craig8johnson: I'm checking the charging system. I'm afraid I might have fried the last battery. With the solid state regulator (after market) what should it be charging at. The book says, I think, 15 volts. I'm hitting 17 when revved. Is that too high? Jul 11, 2017 18:06:19 GMT -5

gggGary: Yes 17 volts is too high, about 14 volts is max, sounds like you don't have the right regulator or it's wired wrong. Jul 13, 2017 6:54:33 GMT -5

dean: Just saying Hello, new member who is going to fix up a 79 XS650 that has seen its better days. I will definitely have lots of questions coming up. Jun 23, 2018 16:45:32 GMT -5

tt650: Trying to breathe life into a 1980 that's been stored (indoors) for 25 yrs. Air filters are dry rotted. Have cleaned carbs but she only runs briefly on choke then stops. Need jet setting info and other ideas that might help her idle and rev. Jul 3, 2018 19:15:19 GMT -5

trix13: Hey everyone! New to the forum and am fighting those gremlins!! New charging system, ignition switch, coil and fuse box. Resistance is higher than normal on the ignition pick up so I'm trying to find one. No such luck yet. Aug 16, 2018 8:50:48 GMT -5

trix13: Also, even though all of my connections are clean, I cannot seem to find out why , when at higher rpms, I hit the signals and the rpms pulse with the signals...hahah. same with the brake light. I appreciate all input!! Aug 16, 2018 8:55:08 GMT -5

bob99: how do I post a question. I am new to the forum Jun 6, 2019 10:52:10 GMT -5

adlpc: Hello all! Been enjoying your edifying posts and discussions - and as a fan of the XS650 since my early teenage years happy that I now own a 1980 Special which I plan to turn into a vintage half faired racer. Thank you all for being here! Oct 1, 2019 0:58:56 GMT -5

jimothyj: Hello everyone, I just joined & wish would have known about this site in 2014 when I brought my 1974 TX650A back from the grave. I have spent a good deal of $$ and alot of time on it. Just painted it and working on electrical, I will post pics soon, Apr 10, 2021 2:14:13 GMT -5

louisvan: trix13 - I had a problem with my 1975 SX650. When I got to highway speeds, the engine lost power. The problem was in the connectors. At a certain vibration and the wind pushing on the wiring loom, the connector lost continuity. A bad crimp to the wire. May 20, 2021 1:19:09 GMT -5

deadlykittin: Hey guys,. i have a 82 xs650 special, super new rider, with almost no knowledge on bikes. So was just riding it, getting used to the clutch and all that. But i was noticed its really hard to get the bike to start, using electric start. And the kick pump--- Aug 4, 2022 17:09:55 GMT -5

deadlykittin: loses compression after the first kick. Ontop of that, i noticed it 1, wont go into neutral when sitting still. and now it dies after getting it started in neutral and going into gear Aug 4, 2022 17:11:01 GMT -5
