Most likely the reason for the slipping when cold is the plates can build up a glaze. Mainly from not being adjusted correctly. First I would make sure the clutch is adjusted correctly, then replace the fluid with either Harley Spot Trans fluid or Golden Spectro Trans fluid for Sportsters trans and big twin primary's.

Old fluid or improper type. Doesn't the Sporty use the SportTrans fluid in the year? Other than that, maybe time for new clutch plates. Or the clutch spring may have lost it's spring.
