Just a suggestion - Clutch inspection from outside is a bit tricky sometimes. Jack up Viper, remove trans inspection plate and do a visual inspection on clutch disc and HRB cycles using a borescope.. If everything checks out, Trans removal will be necessary. Could be worn bearings (hrb or pilot), bad helix hub, you'll know soon enough im sure. Always install new Pilot bearing and HRB to ensure solid repair. If these basic parts weren't replaced at time of clutch service, could be an issue. We're Viper clutch specialist so feel free to give a call for tech help if you want.
