Heres a question, Want to use Royal Purple V-Max in the bike, Dino oil is horrid. So, i drain the oil where the tube is, then drain the primary right? Then, Fill oil in the oil fill with 2.8 quarts, then, I take off the primary cover and fill it with the same oil (Royal Purple V-Max 20/50) Fill till its at the bottom of the of the spring(1 Quart)?. I fill it while the bikes straight?

As it has been said earlier do not use gear oil in the primary/transmission on a Sportster. It will strip the varnish off the stator (alternator for our bikes) and then you will have a lot of work ahead of you.
The HD Formula+ is pretty much the only oil that is specifically made for the Sportster shared primary and transmission. It is the only thing I will use there. I run Mobile 1 V-twin 20w50 in the engine.

I use the HD Formula+ in the transmission, but I've also heard of people using Mobile1 Vtwin 20w50 in the transmission with good results too.
The engine oil drains from a rubber tube down under the bike. It's a black hose that hangs down below the the frame itself. It has a plastic plug held in by a hose clamp. Use a screwdriver to loosen (open) the clamp and pull the plastic plug out and the oil will drain out. I usually change it warm by letting it sit for 15 minutes or so after a warm up ride. You can drain and fill it while it's on the stand.
The transmission drains out of a plug under the transmission housing, you can't miss it. It takes exactly one bottle so you don't have to worry about filling it to a certain level. I just fill mine using a funnel through the chain inspection cover (little rectangular cover held in by two screws). You can fill it through the derby cover also, but why bother with the mess unless you are also doing a clutch adjustment.
When you drain the trans fluid, let it drain until it stops flowing, then stand the bike up off the stand to get the rest out.

But the vtwin 20w50 is supposed to be okay for it? I'm gonna have to run to the store tomorrow I think. Have about 1k-1500miles on the gear oil hope I'm okay.

Thank you for the reply. While im there might as well do a clutch adjustment, bike seems to have a stutter while gearing up, like wind shear, like a slight bucking feeling. Cant hurt, Used bikes bug me, ya never know if the pipe work was done with a retune on the chip.

On the clutch adjustment... I did mine when I put it away last year for the Winter, just did the adjustment according to the service manual, and it did make a difference I could feel right away. It's a really quick and easy to do job if you have not done it before.
