Alright well i have the bike on stands and while spinning the rear wheel i noticed that the chain hits the chain guide thats mounted on the swingarm. Is this normal? My slack is within specs its at 1in.

 

pretty sure this is normal, i noticed same thing on my bike, since rear wheel in not on ground etc, theres a bit less tension on the chain. As long as your withing specs, also be sure to check chain tensioner marks, is your chain old/new?

hope this helps

Bike has 10,300mi on it. Whats a chain tensioner mark?

 

you know when you adjust your chain's tension, theres lines which indicate chain life, ie new/replace, etc. If your bike has 10000 or so miles the chain should be ok, have you adjusted your chain before?, sorry just asking.

good luck

 

oh i dont have all the stickers either lol, i took pics first then removed them all, looks much cleaner

 

Well i have that and my slack is in spec but im wondering why its hitting the guard, makes a good amount of noise.

 

the fact that it is on stands shouldnt change the tension on the chain. the weight of the bike is still being supported by the swingarm, whether its on the ground or on a stand. the bikes weight is still the same. I cant rember for sure, but I think mine does the same thing. except I have a factory piece of rubber on the chain gaurd where it hits. Also remember, those chain indicators on the axle slide are very unreliable and sloppy-atleast on the F4i. and they are completely useless if the sprocket sizes have been changed.

As for why it hits the gaurd when you rotate it by hand, I assume that you are rotating the tire in the direction it normally travels. Thus you are using the rear sprocket to drive the chain, and the tension is now on the bottom of the chain as you are pulling the chain from the countershaft sprocket up on the rear sprocket, all the slack is now in the top of the chain. If you turn the rear wheel backwards, you are now pulling the chain from the countershaft down over the rear sprocket. slack is now in the bottom of the chain. It is the opposite effect when the bike is actually running, because now the countershaft sprocket is pulling the chain from the top, thus there is always tension on the top and the chain should not slap the chaingaurd when in riding, assuming slack is in within spec
