I just got through tightening my chain and i noticed that there is so forward and backward play in the sprocket.Is this normal?I am not stupid about motorcycles cause i have had a few but for some reason i think I have to baby this bike and any second its just gonna break apart.BTW its a 2003 TBA with 8k on the bike.anyhow the sprocket moves a little when i let out the clutch before it engages.1/4 inch play maybe a little more.Thanks
