someone82 Posted October 8, 2009 Report Share Posted October 8, 2009 1st, was the upper roller damaged when you installed the new chain? 2nd, new chains do stretch. 3rd, do you check your chain slack with the rear suspension loaded or unloaded?

tonyp Posted October 8, 2009 Author Report Share Posted October 8, 2009 thanks for reply! roller was down to almost nothing, yes checked slack loaded me on the bike, chain is a oring and 104 links i belive. chain adjusters have about 1/2 inch of adjustment left to bottoming out, roller you think? or maybe the dropping of 1 tooth on counter sprock is giving to much slack.

Dropping one tooth on the counter shaft sprocket will take away some of your chain adjustment. Quote Link to comment Share on other sites More sharing options...

Replace that roller, it affect how the chain will tension up. Wait is the top roller or the bottom? The top roller keeps the chain from coming up when the rear suspension is compressed and the bottom roller put tension on the chain going to carrier to reduce the chance of the chain skipping. If the bottom roller is chewed up replace it and you will notice a difference on how the chain will tighten up. Also with the smaller sprocket it will require more adjustment if you don't shorten the chain accordently, but normally you can saftly go up a tooth or down and be safe with the same lenght of chain. I switch from a 13 to 14 all the time depended on my rear tire size and what type of riding I'm doing. Like I said before new chains will slack up after a couple of rides, and double check that you carrier bolts and adjusters are still tight. If your still fighting the chain being loose after all this, you might just have to take a link out. Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted October 9, 2009 Report Share Posted October 9, 2009 If I drop one tooth in the front I try to add one or 2 to the rear. A cheap chain will streatch more than a good quality one. Chain and sprockets are not an area to go cheap on. I run a RK GB520 EWX or what ever it is called. Quote Link to comment Share on other sites More sharing options...
