I pulled my swingarm out at 12k miles and although everything was pretty grease-free, it wasn't worn. Packed everything with Silcolene Synthetic (waterproof) grease and re-fitted everything. I figured if it'd done 12k without grease it should do a lot more with grease.
However... I've still not done my head bearings (keep forgetting)
Just hope I'm in-time there too
