A short time back I decided to change gear ratios on my stock 75. Us Canadians have learned to be patient folk when ordering parts from the U.S. ,shipping , customs, brokers.... While waiting for my new chain and gears from Mikes a fellow rider on a 650 site said he buys heavy duty 1/2" drive chain from a farm supply co. and fits it to his xs. The only prob was his stretched out in 1000 mi. Since I had 22000 on my orig chain I was gonna show him. 10 ft on sale for $ 17.99 cut it down to 104 links, gobbed on the chain lube and went ridin. Coming home from my girlfreinds at 2am 65 mph on expressway it snapped with a vengence. The four seconds of grinding gnashing sounds ,I thought I killed my beloved 650. It jammed in the case and I couldn"t pull it out. Cell call to freind and with my head held down the trailer ride home was like a funeral procession. Stayed up to take it apart and the xs Gods smiled on my ride and no damage. 300mi on that chain and the master link was still intact. New gears and real motorcycle chain on , I'm back. Although it looked like a bike chain there was a difference.

My god man ::)you can just go buy any industrial chain!
Brings back the sight of one of my fellow rider's road rash and left side swing arm. (bent down to the ground after chain snap+wrap) You are the lucky one not to have damage. On the other hand, I've seen them merely deposited on the pavement too. I regularly have thoughts about how my chain is going around while I am riding.
Over 100,000 miles now. That sucker cost me $950 in '82
Eeky - Lucky that your bike wasn't hurt, but DAMN lucky that YOU weren't hurt, too - It would be a nasty show if it had jammed the rear wheel while you were doing 65, and you'd had to lay it down with your g/f on the back........
Think I'll wait for a real chain...... (at least I have all winter before I can ride it again.....)
BTW - what part of Canada you in?
Definition of an Expert-
An Ex is just a Has-Been, and a Spurt is just some poor drip under a lot of pressure.........
Shakernorm, I was riding alone when the chain snapped, but either way could have been a lot worse than just learning a lesson. I guess you have to trust the package because the chain that snapped even under close exam looks identical to the new chain. Makes me wonder about all the swap meet treasures guys carry home. I'm no greenhorn, I've been riding my 75 from the showroom floor, almost 35 yrs on the same ride, but never did I think that chain would go. I expected it to stretch faster not snap. I'm in southern ont, outside Windsor but have criss crossed Canada and the U.S. on my xs.
I replace my chain every two years regardless of condition. I pay about $60 for the new chain and throw the old one in the garbage. Cheap insurance.
I am always amazed at members who will spend all winter and hundreds if not thousands of dollars redoing their bike with expensive sexy parts but when it comes time to put it back on the road, they buy cheap chains, brake parts and tires.
I'm also amazed that you can buy a used chain on Ebay. I'm not amazed that someone would sell a used chain, but that someone else would actually buy a used chain, perhaps to save $20.
There is a recent post here that describes an accident caused by a broken cheap chain that put down two bikes riding close together and resulted in three fatalities, but members still keep looking for and buying cheap drive chains after they have spent $600 getting their gas tank painted.......go figure....
I was going to wait another year before a new chain, but changed my mind when I began reading posts about broken chains. I ordered chain/sprockets from 650central.com, got good prices, but advice from Michael was worth even more.
Apparently there are industrial chains that are supposedly stretch resistant ... and the majority of them aren't ... bike chains ... well O rings, X ring, Q ring, Z ring, whatever ... you can spend 80-100 bucks + and still end up wiht a rubber band. Industrial chians are 20 bucks a 10 ft or there abouts. Maybe worth checking em. Its called a 50 chain, I dont believe its called a 1/2 inch chain. Cool. Srinath.
I'm at a loss. There were a couple of posts in this thread telling horror stories of people using industrial chain and having very bad consequences. There is one post that tells a tale of three people being killed dead because of a cheap industrial chain and the owner of the bike that used that chain was arrested and tried for manslaughter, but then, you come along and blithely talk about industrial chain for $20 for 10 feet and "Maybe worth checking out".
Like...do you read these threads before you make your "contribution"? You're like a loose cannon....
Re. specific chains, I currently use a 520 EK x-ring on the XS, 525 EK x-ring on my Zook SV650; very durable.
Srinath, your "apparently" and "supposedly" don't quite plaster over the fact that you don't know what you're talking about. When you're on life-and-death safety issues, write from experience or button it up.
The rule of thumb for chain wear is to pull the chain out from the back of the sprocket. If you can expose half a tooth or more, the pins are worn to the point that replacement is needed.

Regarding the use of industrial chain This type of chain is designed to take a constant load and is rated at about a third of the strength of bike Chain the loading on motorcycle chain is expected to take large shock loads ie you hit a bump in the road Industrial chain is used for constant loads ie from electric motor to gearbox, How do I know this I worked on the design of drives for industrial Machines? For 10 years DON’T USE IT IT CAN KILL if not can make a good job of destroying your engine cases

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.
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!!

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.
