Stupid question but...have you carefully checked your belt to see if there are one or more cogs that have sheared or partially sheared off allowing it to jump once in a while?

Its not the primary fluid or the primary chain I just finished servicing my 02 883 and adjusted the primary chain and the old SYN3 fluid still looked new after 5K.
It slipped one time in first gear after the clutch engaged when the bike was cold and about 3 times in the past when it was cold also so this sounds like a built in feature for this tranny to me.
Will be interested to see what the gurus come up with for the fix keep us posted.

It's probably the dogs on the gear have worn down. As they become rounded, they can jump out of gear until they catch at the next dog. This is a known issue in those bikes (seems to be around the late-90's up to '03). The fix is to replace the gears that have worn in the transmission. The new unit is revised.

My bike does the exact same thing, and that is the problem. I'm just putting off the fix until I feel like dropping the time and money. It won't damage anything likely, just a minor inconvenience.
