Replaced what was left of stock chain w/ RK x ring and a new 12 tooth sprocket. Bought a new one for back havent got around to it(47). Does it matter which way the fr. sprocket faces? It had a groove in one side and I put it facing out(Primary Drive)?? Anyway, after the 2nd ride I cleaned the chain w/wd, then good lube. And when I walked it across the garage the chain/sprocket were making alot of noise(new clicking noise?) - is this normal? Is there something I forgot to do - I'm paranoid. The chain guard doesnt look right either. Does the o/x ring still need the 3" slack as per the manual? Sorry about all the questions at once, I'm either extremely inquisitive(mom said), or really stipid(wife). Thanks
