It goes away after it's warm?

i am no expert on a rattle there...have you tried adjusting the cable slack?-and if this makes it go away-i`d still wanna find out more info-a factory service manual sure comes in handy and wish i had one for all my bikes...i disconnected the decompression cable on my yamaha xt250-and it caused me no grief-and it worked fine when i hooked it back up after much riding...it just makes it a little harder to kick over-but gives more stroke to the kick...it also causes more strain on the kick lever and shaft...i`d suggest washing the motor,tear off the cover and check it out...and while you got it tore apart-checking valve clearances and inspecting cam wear can spare alotta heartache-that`s my 2 cents worth

yeah after about 10-15 secs its gone and you won't hear it again until the next day

Could it just be it's cold and doesn't get oil? If it only does it when it's cold I really wouldn't worry about it. But then again, you'll have to make that call since I have no idea what it sounds like?
