If I want to change my stock handgrips...

No glue required. Not only do they look sharp they are very comfortable. Very high quality. Plus some guy in Texas vice China still has a job.
 
I've been putting off getting some new grips...and they replaced BAD! I need something with the ends open or semi-open as I run handguards, especially in the winter and I have a brake-away throttle lock so i need something that'll be compatible with that too. Any suggestions?

You can still use Avon - Their tip is to cut the end off with a hacksaw. I jest not. Works too.
 
If girth is the aim - then look at Grip-Puppies and similar. These are a sleeve over the original.
I use Avon on the R3.

I tried a set of those.
They were comfy and reduced grip pressure to hold and twist the throttle . . . Until I rode in the sun at temps above 90.
They $hit the bed!
 
Humidity perhaps?
Grip Puppies are English so Humidity should be OK.

I'd guess more something used for cleaning. I have a wide range of solvents in my workshop - can be quite revealing how some rubber/plastic resists (or does not) certain classes of solvents. I use Dog Shampoo and water on the rare occasions I actually wash my bikes - usually just need to remove bugs and they come off (usually) with just water.
 

Sure . . . Just water AND elbow grease!
