Hey people.. I just want to throw this out their. The chains that come with these kits are nothing but junk..They stretch and stretch and constantly pop off....Throw them AWAY!.. I just put on a #41 chain yesterday and have had zero problems... My bike was setup perfect. All my problems were the results of an inferior product.. You can save yourself's a a lot time and grief by running down to Northren tool and picking up a Drive Chain #41 | Chains + Sprockets | Northern Tool + Equipment and dont forget a Heavy Duty Chain Breaker..
