Ok so hello everyone got a few tech questions first let me explain the situation I picked up a 1983 venture a week ago I took it on a couple mile test ride no issues I took it to the store (a few more miles) no issues then I took it on the 30 mile trip to work the whole way up the bike ran great no issues I got to the stop light before work and shifted into neutral when the light turned green I shifted into first and all I got was a slight grinding noise more of a grumble than a grind she shift easily into all gears but the is no drive or pull when the clutch is released ? I have since pulled the rear wheel and when I pulled it I started the bike and shifted into gear there was movement but it was weak enuf to not spin the tire so I pulled the rear drive and shaft it seems to be fine all splines are good and no unnecessary play I pulled the left cover off and when I pull in the clutch and shift from n to first the nut in there doesnt spin freely but in n it does any ideas as to what the hecks going on? If I did a poor job of explaining please feel free to ask any question or make any correction
