Sound like it may be the chain, what make you think it's coming from the clutch. Might be the chain, chain alignment, or the sprocket teeth needs to be beveled to remove the sharp edges on the teeth.

It could be the chain i need to flip my clip but it rode smooth with no grinding or scraping earlier could i have sucked something into my intake causing the noise or clutch pin scraping

The clutch shaft is isolated from the engine itself, so if you sucked something in it wouldn't be a factor.

As you can see that the two areas are each sealed off from one another. This picture was taken for another thread, disregard the arrow.
