when i go to take off i hear a loud chatter, i think it maybe the chain, the chain definatly needs to be replaced and it is very loose so can this be the problem? the clutch was replaced 300 miles ago and i have been taking it easy for the break in period, maybe this?? i need help, thanks guys

 

Well how loose is it? When you push up on it between the sprockets, does it hit the bottom of the swing arm? How do the sprockets look? Post a pic.

 

sproket looks good, and yes, it hits the swing arm badd, the spot were you adjust says to replace so im gonna but i wanna make sure tis not something else too

 

Too much slack definitely causes rattling when you take off from a dead stop. A dry chain can also cause rattling. Lube and tighten the chain. If the chain keeps drying out and slackens every time you tighten it, time for a new chain and sprocket kit.
