Having been out of motorcycle riding for so long I am still playing a little catch up.
As I have new rubber on the bike what is the best way to balance them?
I have come across 3 options. 

1) High Speed balancing. Not sure of the price.
2) Static balancing - not sure that is the right phrase or not.$10 a wheel
3) This liquid you put in the tire called Ride-On. About $16-$20 a wheel 

Thanks for any input.

(1), (1) and (1). Should have been done on a dynamic balancing machine when you had the new rubber put on; at least, it's always done where I change my tyres. Check to see there aren't any bright shiny new balance weights on the rims.

I like/use Ride-On.  Makes it easier to clean the wheels and you don't have to clean up where old weights have been after tire changes.  Also slows down gradual pressure loss.

Most tire dealers dynamic balance the tire when they install it.  That's probably the best.

I change my own tires and static balance them.  One thing I've learned is to check the wheel with no tire installed.  I mark the heavy spot which doesn't line up with valve stem.  This is where I line up the mark the tire has.  It makes static balancing a lot easier on the BMW alloy rims.

As far as the Goo, I used it back in the 70's in my enduro bike tubes once.  Had a torn tube and the stuff got out.  What a mess!  I've heard that tire guys hate that stuff and refuse to change tires if they find it.  From my experience, I can't say I blame them.  Same with those beads.  Tried them once, when I changed the tire the got all over the place.  Never again.

Once it's been in there a while Ride-On kind of sets up and makes no mess when the tire is removed. I've changed tires by hand inside on a rug and there was no mess.

I changed my rear myself a couple of weeks ago and found out that the previous tire had the dyna beads put in it.  I transferred them to the new tire and they seem to be working quite well.  I had the bike up to 170kmh the other day and had no issues at all.  There were a few beads rolling around the shop during the tire change but no great mess to speak of.   YMMV though

I got new tyres on yesterday, balanced etc and all good.

But the previous set was 6 weeks earlier.....would the goo have set in that short time...?

Short life span for that set but not complaining, a lot of miles were done in the time.

Don't know how quickly it sets up.

I did ruin a brand new rear tire once that got a big nasty piece of metal in it within just a couple of days. I took it to Chaparral in San Bernardino to get a new tire mounted. I did warn them about the newly added Ride-On when I dropped it off. I wasn't there when they put the new tire on so don't know for sure if it caused them issues or not but they didn't seem upset about it at all either when I dropped it off or picked it up the next day.

I've been using Counteract ceramic balancing beads since early last Summer in all of my motorbikes tyres. These are similar to the brand known as Dyna Beads. I push them into the valve stem after core removal using a clear nylon tube of about 75mm in length slipped over the threaded part of the tire valve and with short, light bursts of air from my Best Rest Cycle Pump compressor. 1.5 oz go in most front tyres and 2.0 oz out the back. On bikes with TPM systems, like my K1300GT has inside the rims, I have found it best to pre-balance the wheel with 'old school' weights before mounting the tyre. The tire pressure monitors are surprisingly heavy and I'd often end up with more than 2 oz of weights on the rim, otherwise. The beads are supposed to spin round inside once underway and gather at the opposite side of the heavy spot. At speeds of 140+ mph I feel no imbalance (off highway, of course, nudge, wink).

When removing a worn tyre I break one bead down and make my best attempt to rescue the tiny bastards from scattering across the garage floor, using a 'Dixie' cup of sorts. The ones that get away become micro bearings that are amazingly slippery on polished surfaces. I retrieve 75% of them for re-use. When they do spill they will eventually break down and not end up in the gut of the fish you're having for dinner like micro plastic does. Curiously, about 50% of them change to a white colour and the other half appear black. There's your yin & yang balancing act, baby.
