stupid chain..
so turns out it's kinda hard to ride a bike home after it spits its chain out. halfway home from visiting mattie_k & co, i lose all drive and assume my clutch has blown up. but nope, it's the chain. lyin in the middle of the road (glad there was noone behind me). no damage to the bike that i can see. fortunately my cell phone just BARELY got a signal thru and mattie_k + family patriarch come rescue me with pop's behemoth of a truck. now what's the chance of me getting a replacement chain tomorrow by lunch? i wanna go riding this weekend!
now here's the interesting part:
first of all it didnt break a sideplate, it snapped a cross-bar (for lack of the proper term) right in half. it was the masterlink no less, which i'm not sure is surprising or expected. what's also interesting is i had just cleaned my chain before this ride (well, a day before but hadnt ridden it till then) with WD-40 and a brass brush (it was REALLY dirty), wiped all the WD40 off as best i could, then lubed it with 80W shaft drive oil. i was thinking the WD40 may have fucked it up, but of course it didnt break anywhere near the o-rings so i guess not. more generally, i assumed the clean & lube somehow helped the chain on its way to retirement, but again i dont see how that could have contributed to a break in such a place. any thoughts?

Probably knocked all the rust that was keeping it together loose with all that cleaning you did. whoever said that a clean chain was a happy chain was lying!

wasn't an RK chain was it?
sometimes they break, especially on high-powered machines.
how old and how many miles on that chain?

Probably melted with all the salt it was exposed to.
(DON'T RIDE IN THE WINTER)
You really should be riding a dirtbike that can take the abuse you put your machines through.
You are so lucky that didn't happen on the way home from Laguna.
No way those small towns we stayed in had motorcycle shops.
You would have been renting a truck, again.
Except those towns were so small they didn't even have anyplace to rent a truck from.

chain was a DID 50ZVM, the strongest one they make. probably 15,000miles on it? at most that is, cause the chain was less than 2 years old. i fully expect that princesskiwi is right, that riding thru teh winter did it in. having said that, i looked at the chain this morning in the light: it was the master link that went, and it looks to me liek there was a defect in the metal, judging by the break pattern. i'm no metallurgy expect of course, but i've seen similar patterns pictured with defective materials before.
no kidding i'm lucky it didnt happen on teh laguna trip. i prolyl woulda got away with it ok cause all i needed was a master link, but it still woulda taken up several hours, and for all i know there may NOT have been a masterlink available. man that woulda sucked. hence teh reason i had a once over of my bike done before i left and specifically had the dealer check the chain to make sure it will last. i guess they were _kinda_ correct in their verdict. i woudl be a bit dissapointed but if it is inded a defect, then there is no way the mechanic could have known.
anyway, putting a new masterlink on it temporarily till i can get a full new chain on there asap.

Maybe the Person  that fitted the Master Link sort of over did the Rivet part and that is how the metal got weakened? Agreed that you picked a good time as opposed to the Trip where you would have died in the heat and Frustration of being on the side of the road like a few of our Grudge Match visitors did on the Beltway in Maryland

whether it was improperly installed or/and the issue of high corrosion, i'm beginning to think that the shaft broke some time ago (as in over a month ago) and i have been running a split link for some time, as all teh damage to teh sleeve is on the sides, as it would be from a bent/broken shaft slowly slipping out, plus i noticed what felt like a bad kink all thru the laguna trip. with the new master link in, it's smooth as silk, but i ordered a new chain anyway cause of the one damaged link. plus who knows if the corrosion caused problems with other links.
bloody $230 chain (after tax) tho. arg! good thing my sprockets are still in good shape.

I think I remember seeing a picture of that chain posted on this board once.
Wasn't it composed of 70% Rust enhanced lubricating molecules?

sure i can. it was prolly 10,000 miles or less, and my first chain got me over 20,000 with little to no maintenance and plenty of abuse. actually my current chain is in good condition other than the damage caused by the master link breaking. zero tight links.

questions for you freek.........
#1. Were there new sprockets installed with the new chain and if not why and how many miles were on the old sprockets?
#2.When the new chain was installed, did the installer check for tight spots after adjustment? (did you check for tight spots?)
#3. Was the chain a Rivet link chain and did you check for cracks in the end of the pin where it gets flared? (As VincentHill had pointed out...the installer may have gotten a little crazy with the flaring tool)

#1 new 17t front sprocket was installed with last chain. believe the rear is still the original stock sprocket as every mechanic has said it looks fine (including just now in preparation for the third chain)
2. don't know about the installer. if "tight spots" means the same as tight links/kinks, then there are none.
3. yes, rivet style (i dont think u can even get a circlip master link for the DID 50ZVM). end of the pin looks ok. it is sheared in half right in the middle of the shaft.
DID50(530)ZVM is the same as the stock chain isnt it?

Looks on sprockets are very deceiving.........Personally, I would NOT mix old and new parts when it comes to chain and sprockets.....not a good mix ( take it from a 23 year motorcycle tech.)
Get rid of the old front and rear sprocket...new all the way around!!
I know I know...tight budget, but next time you may not be so lucky, may tear up your engine if the chain wraps around the countershaft sprocket or tear the bike up if it decides to wrap around the rear wheel and swingarm, and we all know what may come of that....perhaps a crash included.
When I say tight spot.....I mean you adjust the chain and spin the rear wheel and check for the chain turning into a banjo string or having excess up and down movement if you were lucky enough to adjust it at the tight spot.

ah, i will check for a tight spot, maybe tomorrow.
i expect i'll take ur advise on teh sprockets, but out of curiosity, why is mixing old/new sprockets/chains bad? certainly not the first time i've heard that said but never heard the reason behind it.

old sprockets tend to wear new chains at an accelerated rate.
the chain has to work harder to grip the worn sprocket teeth.

thx fer the advise fish, but i'll keep doing things my way. i happen to like understanding things instead of just following rules.
XL, makes sense when i think about it. i suppose it's mainly a result of the "sides" of the teeth having a greater angle from the vertical as they wear? but which part of the chain actually has a harder time dealing with this? the rollers i suppose?

Always new sprockets with new chain. And when You buy OEM one-piece chain You don't have to think if the master link will last or not. Yes it's a little more trouble to put, but it makes You remove the swingarm so it gets lubed. And really isin't that big of deal. Dosen't take many more minutes than riveting the chain...
