Chain suddenly stretched?

Given that Amazon sells all manner of things, they have customer reviews that look to be legit. Maybe this chain and sprocket kit is just crap.

I am not yet convinced that "hard" downshifting is not some of the problem. We all blow shifts from time to time but down shifting is a smooth operation if done properly, one gear at a time.

 

Regarding replacing a master link every 8000 miles sounds :crazy: I know you did'nt mention it; but why? Was the part that was staked cracked? If thats the case, its the fault of the installer. I replaced a staked master link that upon close inspection had cracks on the rivet from the previous installer botching the staking process. You have to be careful not to masacre those rivets when your mushrooming them with the "TOOL" (good band :rockband

Yeh I am sure there are some really ham-footed down shifters oot there. When I was involved with road racing there were quite a few 2 stroke riders that would blitz into corners and at their last brake marker would brake and pull the clutch in and bang three of four down shifts, and then let the clutch oot. One doode comes to mind who was an older gentleman at the time (maybe 60s?) well he blew his turn, turned oot that he thought he was letting the bike oot in maybe second and was in some other gear, (foggy memory here.) Point is, he ended up in the tyre barrier and got a ambulance ride to the local hospital. Never saw so many black and blue marks before. Some stuff you don't forget. Wheelies destroy chains me thinks :loco:

 

Hope you find a resolution to your problem. But I would not be too quick to throw any blame on the Chain Saver. I have been using it for maybe 4 or more years now and through two maybe three DID chains that I got more than adequate mileage out of. Is it the best out there for lube, I just don't know. But it certainly is not bad stuff. It is about the cleanest. I hate all that fling I used to get with PJ1. The Scott's auto oilier was given a lot of consideration, and if you are leaning towards thinking you are not getting enough lube on there, then I think that may be the way to go for you.

Let us know what you end up doing and what the results are. Next time around, we may be asking you for advice. Except Badbilly of course.

 

Definitely not the lube. Probably just some out of spec parts. I like DID EVR chains, have had great luck abusing the heck out of them. From what I remember EK used to be good then they went sub par but supposedly are good again. Not sure but I would do a little research on them.

 

What you say is probably true. This guy may have had more bikes and more riding time than many others and unlike some whose entire knowledge is based on a one bike experience and several leaky jackets. Kind of like putting all your huevos in one cesta.

 

Also never use a torquehammer on staking a master link or a vampire unless it's silver..

Seen a few dudes drop two cogs on fourstrokes too.. Wheel hop, over revving and jerky corner entry. Gotta be hard on even good chains and sprockets.

 

I think you proved the EK chain isn't among the best. :frown:

 

Given that there's a half-dozen pairs of black monkey nuts (rubber dampers) between the hub and the sprocket carrier, it is not possible to downshift and do damage to the chain. You might do some valve damage in the heads from over-revving the motor on a high-rpm downshift, but you are probably not doing those sort of shifts either.

Racing 2-strokes can bang the downshifts without using the clutch since there are no valves in the head--the only time i ever used the clutch (rs125) was on the starts, although i might use it now that i'm a pussy and old and can't tolerate getting hurt anymore...

 

Monkey nuts in the cush drive? YIKES! Maybe a good idea to pull that hub apart and take a looksee.

Same on two-strokes upshifting and if done well, upshifting four strokes. Banging a downshift on a fourstroke can be done but why?

I think Squirrelman hit the ball out of the park with his observation..
