Primo Rivera Primary Belt Drive

It wont get you kicked off.

With respect to your belt drive… if the nut is coming off it may not be the belt, Check the offset spacer. The “book” dimension for the 250 LSD drive primary spacer is 1.4375″ check the dimension and have the spacer remachined if it is any wider. Also you need to make sure the nut is properly torqued.

From our line QC Checklist
65. Main Shaft Nut (@ 185 ft lbs • Red Loctite)

Finally, our dealer in Corona, CA swears if you grind the powdercoating off the charging system rotor the nut will grab more threads and not become loose from gradual compression of the powdercoat. We were not convinced… but it dosnt hurt to do it.

FYI – I ride a 2003 Vendetta with a 1.4 spacer and have never had a main nut come off. IMHO its the spacer, check it.

For those of you who are looking for technical documentation this will be interesting…
