O.K. guys this is driving me nuts. I've got noise that sounds like it's in my trans. It does it mostly in 3rd,4th,and 5th. It happens at a steady speed I can speed up or slow down and it will stop. It sounds like the bottem end is going to explode when it does this. It also viberates like hell when it does this. I've tightened the chain and it made no difference and replaced starter gear so i've checked everything on the clutch side. It also makes a clunk when you put it in first. Kind of like it does when chain is loose. Anyone ever had anything like this?
Hey Ogle.... Freakin Rattles drive me nuts and the xs is full of them. Fix ne and another appears. That said almost all the rattles I've had sound as if they are coming from the same place, in front of me. The windshield only made it worse. The worst noise I had was when the front sprocket nut loosened. It caused that thump into gear noise for sure. Check for night stand or kickstand rattling on pipes, loose side covers, wheel bearings, broken springs in the rear brakes, bad front brakes, exhaust leaks, chain (also make sure it tracks on sprockets right) chain guard rubbing..........anything I forgot guys?? Mike I also had a freaking loud noise at low speed. A magnet had wedged itself between the frame and the rear sprocket. It hit the bolt when starting off and whined at any speed.

targis34 didn't miss much....I think we have all experienced your symptoms. So, to separate the noise from frame or engine, try revving the engine while riding with the clutch disengaged and note if the noise comes and goes with engine speed. Then try coasting down a hill with the clutch disengaged but still in gear. Also, the windshield does tend to magnify any noise and make it appear as if it is coming from the front of the bike, just as targis34 suggests, so if you have a windshield, remove it and try the tests again.
The one thing about your symptoms that I am troubled about is the apparent level of vibration. Of course, it's a chicken and egg deal.....it takes a lot of "natural" vibration to cause parts to bang together. I had a similar situation shortly after I got my bike and actually removed the engine and was going to tear it down, when I noticed a hole in the exhaust pipe that had been banging on a bolt, but only at 3,200 RPM....

If your machine still has the stock exhaust system on it, plus the center-stand. Be sure and look at the rubber bumper on the bottom inside of the left muffler..Right where the left leg of the center-stand ends...If that bumper is missing..the center-stand makes a rattling noise that comes and goes as the RPMs increase and decrease @ around 3K or so...I looked for nearly a hr once when my 82 suddenly started the same type of noise..The rubber snubber was gone and the left foot of the center-stand was making direct contact with the snubber bracket on the muffler. Good luck and please do let us know what you determine as the cause..
Yamaha XS650, the past is a just a blur in the mirrors.

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.

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.

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.

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.

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!!

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,

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.
