1979 XS650 funny noise.... little help?

[skaere]

Hello all! new to the forum.

got an XS650, 79 special II a little while ago. love the XS. but its making a funny noise.

best way to describe it. its a light clanking (metal on metal) noise like something is loose on the bike and rattling against something else.... but i've checked everything and cant find anything loose, even when im touching parts of the bike while its running to see if they are vibrating.

other part thats intriguing me is that it stops making the noise once i run her for a while (maybe 5 min)

i tried to locate the sound but its hard to pinpoint. sounds like either (bear with me here....) the area where the exhaust bolts up or from the end of the muffler.

thanks!!!!

Have you adjusted the camchain tensioner? If it is a tack-tack-tack type noise it could possibly the plastic part of the front guide coming loose.

i havent yet. gotta look up how to do that.

other thing i noticed is that the noise is a constant pace, regardless of engine speed (doesnt speed up when i rev motor)

im hoping its something loose in the exhaust, prev owner said he knocked out the baffles but im not sure how he did it.
