For me, golf grip tape is the only way to do. Wrap the left side with tape. Wet it AND the inside of the grip with solvent. Slide the grip on and wait for it to dry. The beauty of the stuff is that you can make small adjustments for quite a while before the stuff sets up. One small strip of tape costs thirty cents. Worth it!

 

My old grips had no glue but when I put on the new grips they moved so I took it apart and glued them.
The glue is nothing special its just contact cement you have to put it on the bars and on the grips and wait a few minutes before putting them together and the secret is only spread the glue out about a 1/2" wide on the handlebars and in the grip then put the grip on so thetwo glue surfaces don't touch while installing and once it's on rotate the grip so the two glus surfaces come together and it is instantly glue in place and if you have to remove it some day you can still get it off.

 

My left grip came loose all by itself.. no idea how.. was tight one day, looser than sh*t the next..
Racked my brain trying to figger out what to use to put it back on... ( Kuriyakin Grips...love em...)
Finally had a brainstorm... I work in a Dental Office.. and we use a spray adhesive for our impression trays... sprayed some on the handlebar.. slid the grip on..and is rock solid.... yet it isn't a permanent glue so it will come off easily later..just makes the surface tacky....

 

Only time in years I've used glue on a grip was on grips that don't have full surface contact with the bar, like the Kuryakyn Iso Grips. Those you have to glue on. For grips that have a full contact surface I clean the bar *really* good to remove any oils & debris. Then I pour a little gas into the grip, splash it around to coat the entire surface, dump it, & while still wet shove the grip on the bar. The gas provides enough lubrication to allow the grip to slide on, & when it evaporates the grip & bar are stuck together. In 40 years I've had two loosen on me, & as soon as I felt any loosness I injected some oil to get the grip off, cleaned as before & reinstalled. You can do it at a gas station on the side of the road. Works for me, YMMV................
