primary fluid question..
As a side note, I don't have any more clunk when shifting from neutral to first after I start the engine since the switch. As always, FWIW and YMMV.
Many here use ATF in the primary. It works well, can be found almost anywhere, and it's cheap. Cheap enough to change out every time you service your bike as I do plus this application (the primary) is what ATF was designed for.
Keep these three things in mind: motor oil in the motor, gear lube in the transmission and ATF in the primary. Use the correct lube for the application.

You could also check your tranny fluid....overfull could cause slippage....don't forget to check level in upright position.....
Hopefully it's a simple fix....never fun when bikes not running good.....

HD Formula+ primary/tranny oil is okay for the primary, but IMO very over-priced at ~$6.50/qt. I would not use it in the tranny, opting instead for an 85w140 or similar viscosity gear oil.
Some cars do have ATF in the manual trans . The Borg Warner T5 used in TVR's &Cosworths in Europe and I believe the Mustang use ATF dexron 11. Think about it autos have epicyclic gears in them.
all the oil in the primary does is lubricate the chain and bearing in the clutch hub.
