Like others have said let it sit over night and check the drain pan in the morning.
You can flush it with the factory fluid that's suppose to go in there.
Just let it drain, refill with fresh factory fluid, run the bike up to temp drain again and refill with fresh fluid.
That should clean most of the old stuff out.

What I do is put in on my lift and run the bike in 2nd gear for a couple of minutes at about 25mph. This will warm up the engine and trans quicker with that load and make draining the trans a whole lot easier.

I am trying to change the oil and its not coming out I didn't have chance to warm the bike up and go threw the gears. So my question is can I spray brake cleaner in the hole to thin it out so I can and fresh oil since I am going in for surgery on my back on the 29th.
thanks for any help.

Shockproof is some sticky stuff. I've been running it for about 20K miles, changed it twice. It'll drain out, but I've noticed even drained, it leaves a thick coating on the gears (at lease what I can see through the filler hole).
If that's what you are referring to...seeing the reddish coating on the gears, I really don't know how to flush that stuff out. Be interested in hearing ideas from the board though.

I never had a problem with it draining, though. Yes it does come out a bit thick, but it should still come out. Maybe you got a sludgy spot on the drain hole? Maybe stick a small screwdriver or coat hanger or whatever, and twirl it around to see if there's a clog.

Very much depends on your bike. Most of the Twinkies are spec'd at 20k for the transmission.

I switched off from the shockproof also...to get most of it out, i drained it first, put drain plug back in and fill with some 20/50 engine oil, run for a few minutes then pull plug and drain again, then refill with your tranny fluid.
Ride safe.

What was the reason you switched back from the redline?
