Just to repeat - if you are running an Enfield with a belt drive and thus no oil to lubricate the clutch bearing I would suggest Thermaplex grease for them.
Available online and made by LPS Laboritories, Illinois. It's a HI Temp Bearing Grease. Resisteant to 392F (200C) which will last for thousands on miles without getting melted off.
