This just started happening over the last week. Pull choke and start bike.

Let bike idle for about a min or two. Push choke in. Bike idling just fine.

Pull clutch and go into 1st gear and the bike lurches a little and stalls out.

Kickstand needs to be up.

Or could be clutch plates are sticking. Let it warm up or give it more throttle. Pretty common on TDubs. Before you start it you can walk the bike a bit in first gear while holding the clutch lever that helps free them up too.

What would cause the clutch plates sticking all of a sudden?

Mine does this most mornings. I rev the engine a bit before putting it in first. I bought stiffer clutch springs to try and see if that works but don't know if it will.

As the weather cools...nights are longer...oil has more time to thicken a bit more.
I'll let mine warm up for about 3-5 minutes in the morning, then I straddle it and flat foot it out through the gate. While I'm rolling, I'll pull in the clutch and shift into first.
Usually by then, there's no clunk or stalling.
Another option would be to let it warm up, then shut it down...then shift into first and (with the clutch still pulled in) start it up again and off you go!

If this doesn't work...then you must still have some cut-out (sidestand or clutch switch) still being activated somehow.

Before you start it, put it in gear, pull in and hold the clutch lever, then firmly & quickly push the bike back & forth. If necessary, as HARD as you can. Won't hurt a thing.
That will usually free stuck clutch plates.

If that doesn't do it, then think about the more complicated stuff.
Like my Ol' Daddy used to say..."Pluck the low-hangin' fruit!"

The clutch sticking thing is REAL.

If you pull in the clutch and move the bike back/forth to break loose the clutch before going into gear, it general fixes that issue. For whatever reason it's a thing will many of the TWs. I have had less issues with mine as I put more miles on it. But that sounds exactly like what you're dealing with.

This seems to be a common complaint on newer TW's that have the reshaped clutch discs, but it suddenly happening on an older one is a bit odd.

Cooler weather combined with thicker oil can cause more drag and a bit more of a clunk when dropping into gear for the first time, if your idle is set too low this can stall it out. Might try changing to a thinner weight oil moving into cooler months. I definitely notice the "clunk" is more pronounced using 15-50 oil vs 5-40, although once warmed up both feel perfectly smooth, or as smooth as a TW's transmission ever is.

Oil that's due to be changed tends to drag clutches a bit more also. Could be a factor of a few of those things.

Oil was changed only last month with 20w-50. I set the idle when the bike was warm and it is noticeably much lower rpms right after starting it.

Kickstand sensor removed.
Removed sensor needs to be replaced with a jumper wire or have leads otherwise short circuited to complete a circuit. But then you already knew that.;) Otherwise bike would not even start with an open circuit there; unless clutch is pulled in or clutch lever's sensor similarly bypassed.

If the bike is lurching, the clutch is still at least partially engaged/plates sticking and the stall that results is killing the engine. I wouldn't suspect any sensor/wire with just that one symptom alone, so long as you have the clutch pulled in and the cable is set correctly.
Turn the fuel off, pop the plug wire off and pull the clutch in with the bike in first gear and hit the starter. If it walks you forward, the clutch is still engaged. You can always try it without removing the plug wire, but if it is right before your power stroke you might have a buckin bronco under ya!

I will be checking the clutch cable tomorrow. I just don't understand why all of a sudden the plates would be sticking.

Pretty common problem.

Just grab a handful of front brake, give it a little extra gas, and let the clutch out.

Problem solved.

Did you have a recent cold snap before this happened?
If so, refer to post No.8 above...

Why all of a sudden? They've been wearing down this whole time, it's probably just now gotten to the point where they stick.

Take your clutch apart and check it. If the clutch basket is notched like this, it needs replacing.

^that will definitely cause clutch to stick. Hopefully that's not your problem.

Also just check the plates themselves and see if it's about that time they need replacing. [Usually worn clutch will slip, not stick though.]
