driveshaft? transmission? whats going on? plz help

Ok so hi all I have a problem and was wondering if anyone can help bike is a 1983 venture royale 1200 55k just got it test rode no issue drove to the store no issues then I took it on the 30 mile trip to work the bike rode fine until I got to a stop light shifted into neutral no noises or grinding squealing or hard shifting the light turned green I shifted into 1st and nothing except a grinding noise this is through all gears no power to the wheel it sounds like the noise is at the final drive but im not sure I havent taken the bike apart yet does anyone have any ideas no visible fluid leaks

Likely the drive shaft gear where it slips into the coupler gear is stripped using spline type teeth. The shaft is likely stripped, and the coupler is badly worn. This is located at the final drive connection to the swing arm containing the shaft. Common wear point for the early 1200's. Easy replacement when you finally get the two parts.

I second this opinion as many folks never greased the splines and this does happen.

James,

If you get that rear wheel off and find it is the hub splines, PM me, I have a good hub here in Texas

I would suggest the rear wheel splines as well. Make sure you use the right grease for this application, most greases will whip off of there in 50 to 100 miles.

This is what my drive shaft gear looked like. The red is what is missing off the teeth. Yours probably is worse as I was still riding with mine.

Ok so I messed up and now have two post going it is not the driveshaft all movement and splines are good however when I pull the clutch in it seemed to not have the proper effects pulling the clutch. In while in 1st did not disengage the gear could this me a slave cylinder issue?

Could be the slave cylinder, but first check the fluid level in the master cylinder at the lever. Also bleed the clutch hydraulic fluid system as trapped air will adversely affect clutch action.
