Its much quieter and smoother at 1.5" of slack, and thats not so loose its going to jump off the sprockets. The stock chain is terrible so a higher quality one will help too
I have 16,000 miles on my 2016 and am 4000 miles into the 2nd chain and am hoping it lasts for another 10000 miles, but doubtful. Will be trying to clean/lube it more often like one of the super-mods here who easily gets like 30,000 miles from a chain with only WD-40, but uses mid-day stops to lube the chain on long rides. Not just end of the day or every 400 miles like me
I think Iíll try running it at 45mm. Iím 275lbs so itís possible it likes to run a bit loose AND Iím heavy and it needs a little more slack to account for that. At 55mm it starts to shift poorly and lurch a bit from the slack being taken up so thatís probably too far.
Just a guess on my part, but I think you will have much better results with a new quality chain and quality sprockets x 2. Keep us posted.
Iíll keep an update here after some miles, I didnít know about the ZZZ but Iíll give that shot with some new sprockets.
Get an EK 520 ZZZ with EKís proprietary Zero Stretch Technology (ZST) which virtually eliminates initial chain stretch, and an OEM rubber damped countershaft sprocket, along with new rear steel sprocket.
This makes my chains last very long: https://www.maximausa.com/product/syn-chain-guard/
Forget checking chain slack by the book. Iím positively certain the book is wrong. Iíve been wondering if the book has specs for another bike like er6n or ninja?
With the help of a friend, get the bike upright and loaded such that the front sprocket, swing arm pivot, and rear axle are all in a line. Then check the chain slack. A little slack is all you need at this point.
I bet that once you unload the bike and check slack by the book, you will have what appears to be significantly too much slack. Your chain will be very slack, similar to a dirt bike. But you know that you have just enough slack, so donít worry about it!
At least this has been the case with my V650. Prove me wrong.
Good point, I should try a few settings and see which one fitís this, I think itís probably 45mm. Good chance the factory spec is too tight for how much I weigh, iím Probably compressing the shock more than most unless theyíre two up.
Three chains stretched beyond acceptable wear and you are running the original sprockets?
You will have the same problem again unless the sprockets are replaced.
Crazy right? I generally replace the sprockets with a chain, sometimes not the rear sprocket but always the front. In this case I was on a road trip to Alaska when both chains were replaced at dealers who had no sprockets in stock. To be fair they do look pretty good! Definitely going to shorten the life on the EK chain, but itís a 45 dollar chain.
Dave is correct. As you compress the rear suspension the chain slack will tighten up to the point where center of the front and rear sprockets are in a strait line with the swing arm pivot point when viewed from the side of the bike. This is where the chain will be at it's tightest point. You should have some slack here. If the chain is tight at this point it will cause excessive chain wear and can lead to premature failure.
Iím going to experiment and see what setting works for me. Itís probably a bit more slack than Kawasaki specíd on the swing arm. I was already setting it at the loose end of that spec cause Iím built like Sasquatch and wanted to account for that.
Other than this chain shenanigans Versys is a pretty great bike. I am tempted by an NC750x or a Tracer 900 for the next set of wheels, or additional set. Iíll probably have 50k miles on this one in 2-2.5 years. How long do these things typically go for, 100k? Iím expecting a stator to burn @ 50k.
