New chain issues?...

Right. Fitted new DID gold n black and new Renthal sprockets front and back adjusted up as per manual no probs, since covered about 450 miles so re checked everything, found to be a little on the slack side as expected so re adjusted (30mm slack sat on bike), went out on Friday with the boys and covered another 150 miles.
On arriving home checked again out of curiosity and found it tight, rotated the chain a third and still tight again rotated a third and slacker by (30mm).
Everything still tight can't understand why, seems to me that the chain has stretched in one portion only, has anyone experienced the same.

 

Have you checked that the axle bolt is the same on both sides with a linear caliper or a tape measure

 

I always put the axle nut on the opposite side of swinger so when you torque up your pushing away when you tighten up so that chain does not becomes slack my pref but others will disagree

 

Yes my friend, I'm a bit ocd with things like that considering the energy going through the rear. It almost seems that sumits not centralised but I've checked both sprockets unloaded and all seems bang on.

 

Might be a bad batch of chain ask them to change it

 

you could have said CHAINge it

 

Not sure what difference it would make but is it not 30mm slack with only the weight of the bike on the suspension,not sat on it?

 

As above. The 30mm should be without you sat on the bike.

 

Thanks guys, either way though it doesn't explain why in one revolution the tension alters, I think the only way around this will be to keep the chain on the slacker side to avoid over loading the bearings. Maybe in time the chain will even out.
Didn't have this problem on the hornet and that's got the same setup.

 

Other possibility is that the rear sprocket carrier is not seated properly as you have had it off when fitting the rear sprocket. Check that the cush drive is properly fitted and that there is an equal gap all round once the sprocket carrier is re-fitted.

 

Ive never done a chain, but it isn't tight at the joining link is it, can they be over secured ??

 

Yes you can over do the joining link. Something you would check though when doing this is to make sure the plates can still move between the rollers.

 

Think about how small the front sprocket is, if you have a tight spot in one of the links when rotates around the small front sprocket the size of one link that doesn't want to bend would take up 30mm of slack no problem . Start at the rear and rotate one link at a time pushing up to make sure you get even moment in every link. It could be a defective chain or an over pressed link. If all links have movement turn your attention to sprocket carrier and wheel alignment.

 

get it up on axle stand,rotate by hand , watch chain sag, you will soon see a pattern of events,,dont ride it like that for fucks sake,summats very wrong.

 

Have u spent too much time riding on only one wheel ?

 

You never spend tooo much time doing that Steve . I think the issue is with the rear sprocket, I've reset the sprocket on the hub and it seems better but only slightly, no issues with links as suggested before so I'm happy to carry on riding but will check on a more regular basis no bad thing.

 

There's always a bit of stretch in new chains and depending on where the chain is in relation to the sprockets when you ask for the power you will stretch it more in one section than another.
I'd set it at an average making sure that no section was too tight ( slightly slack shouldn't hurt ) and check it over the next couple of hundred miles ( if on a road bike), by which point it will have stretched more evenly.
Hope this makes sense ( it did in my head as I typed lol)

 

I'm now have the same opinion
