Sprocket and chain question
This is my first reply/ post as I just joined. I have an 08 zx6r. I just changed over to a 15/45 Supersprox front and rear sprocket set with a RK 520, 112 link, x-ring chain from the OEM chain and OEM 16/43 sprocket set. The set was purchased from Supersprox as a set. I also installed a SpeedoHealer v4 to correct the speedometer error.
The install went as planned. Everything is torqued per spec, the axle is plumb on both sides so the chain is aligned and the chain tension was checked in-spec. With the sprocket change the engine RPM is higher as is normal due to the gear change. The bike rides fine however there is now pronounced chain noise when the rear wheel is turning. This occurs under power or by just turning the rear wheel by hand when it is up on the rear stand. It is coming from the front sprocket as the chain wraps around it. There is no binding or noticeable misalignment between the chain and the front sprocket. I loosened everything up this w/e and pulled the chain off the rear wheel and veriifed that the front sprocket is not the cause of the noise: it spins freely and noiselessly by hand. There was no noticeable or abnormal wear on the teeth that would indicate misalignment. I put everything back together and tried adjusting the slack on the chain both tighter and looser and even skewed the axle alignment to see if that would quiet it down. In conclusion the bike is back to when I did the changeout and the chain whirring/noise is still present.
I don't know if this is normal with a sproket change due to the front sprocket turning faster or what. All other indicators are normal, no driveline issues other than the noticeable, chain whirring noise that wasn't there with the OEM set-up. Is this a big deal or just something new to get used to? Thanks for the help...
