loud grinding noise when releasing the clutch

When I put the bike in gear and begin releasing the clutch it inches forward but when I try to take of it grinds real load and doesn't want to move forward. Is this a clutch or a trans issue or something else

Most likely a clutch issue... Might be springs, but if you're going to crack it open, replace all the parts.

check your splines too before ordering parts. the ones from the drive shaft to the final drive.

Dude, your splines are shot. When mine blew, the bike would lurch forward then make a horrible grinding noise. The grinding would stop once clutch lever was pulled in. You can verify this by putting the bike in gear on center stand and feeling the rear hub and driveshaft areas. Might as well pull rear off while you are at it and check the final drive splines and coupler.

Good luck.

Pulled the wheel off it is the coupling attached to the drive shaft thanks for all the advices helped a lot, can I get just the coupling or do I need a whole new shaft?

You will need both coupler and final drive. The shaft doesn't usually fail. The splines may be there on final drive, but working with a new coupler may cause eventual failure. Sadly, the final drive runs for $900 new. If you can find a good used one, go that route. Get some Honda Moly 60 to lube the splines and coupler. The lack of lube is the reason your splines failed.

Good luck!

Spline lubes have to be taken seriously on the Vulcan 750. While many other bikes have this problem, including BMW, the Vulcan 750 seems to be the worst. So many have failed that the supply of good used ones should probably be drying up by now. Dealers and online parts places have new final drives in stock, and may have for a very long time, considering what they cost. Or at some point they may cut the price in half to get rid of them. But how many Vulcan 750s will still be in existence by then?

I am a motorcyclist, NOT a biker.

If I can't find something on there, I change the search terms around and that helps sometimes.
