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.

I think I fixed it
Firstly l know nothing but l had the same problem, I thought about the action and have stopped applying and gearing down any action to 1st gear, I only using second when slowing then 1st or neutral as required after stopping and it has stopped slipping??????

2003 xl1200 custom : I had all the dogs on 1st gear main shaft break off. I was riding and shifted to 4th gear and it was indicating neutral. I pulled the tranny and replaced the main shaft first gear and 2 shifter forks that had some wear on them just to do it while I was in there. The other gears looked fine with no excessive wear. Bike is still slipping and surging in 1st gear only. Makes it a stupid bike when you have stop and go traffic. I saw a mod where someone uses steel springs to pull the shifter forks together and they swear it worked. This slipping makes me want to push this sporty off a cliff....did anyone here resolve the issue?

Slip
'02 1200. The bike jumps in 1st gear occasionally as the RPM's go up. Shift drum is new, new detent plate and retainer (because the old one came off, again). Shift forks are good. Chain and adjuster is good. Clutch is good, cable is good. Dogs on gears are worn, but not excessive. Any ideas out there?
