New chain riding on teeth
-
On my am6 I had a dt 428h chain was no problem I've brought the same chain 428h as I'm also running on the dt but now it's riding the teeth despite it being the same as the one I removed now the one that was on there is riding the teeth too but not as bad any ideas I think the sprocket is a 420 but the 428 was perfect till now?

So what did you do to sort it?
I guess "riding the teeth" is a term where the chainlinks doesnt go all the way down between the teeth of the sprocket...

@Jens-Eskildsen I've not heard the expression before, so I was confused.

@Jens-Eskildsen yeah so the rollers were on top of the points of the teeth hammering the chain down sometimes works but what I did is adjust the chain as tight as safely possible and it will sort its self out mine has and I haven't ridden it yet how ever for countless reasons don't do this unless you really need to

@declan The expression is common in the mountain biking world, with mountain bike chains the 7/8/9/10 speed chains are all different thicknesses and thus incompatible. As the higher number of gears you have the thinner the chain gets, to accommodate the increased number of sprockets it has to jump across. This can also cause the chain to jump as it does not sit flush on the chain-ring and is therefore not fully locked into the teeth. Which is very scary at high speeds!!!
I suspect that you are having the same issue with an incompatible chain and rear sprocket of different sizes? This may have been caused by a previous owner just replacing the chain or the sprocket separately? So the only way to solve the problem is to purchase a complete kit and renew the whole lot, thus giving you total compatibility. I think the 428 pitch is the stock size, but you can run a 520 if you want a stronger more heavy duty set-up?
Wemoto do kits;

@declan Your 'fix' will cause you problems further down the road. Hammering the chain down will damage both the chain and sprocket and loosen the links. Over-tightening the chain will cause it to cut into the sprockets increasing the wear on both and your sprocket's teeth will become 'hooked' very quickly. Both actions will over stress the drive-train and increase the risk of the chain snapping, which is a scary event if that happens at speed and could rip your leg off! Motorbike's are designed to have some play in the chain, this is to combat the reasons stated above.
I would advise you to purchase a new chain and sprocket kit ASAP, otherwise you may regret not getting new one's someday???
