New Grips / Throttle Tube Location

Hi Everyone! I was installing new grips on my 2018 MXR. Left side of handlebar is never the problem. Even though I was lean with grip glue on the right grip, I still ended up with too much glue in the end of the grip on the throttle tube and the throttle would barely rotate afterward. Joy! I had to remove the grip and use 400 grit to clean up the inside of the throttle tube and start over. It seems like the the MXR is prone to having problems with grip glue stickage because of the throttle tube location (as indicated by the Alta Owner's manual is approx 1/8" from the end of the bar) and the throttle tube is totally open on MXR. (Where is ODI Lock On when you need them!?!?!) Do y'all have any helpful solutions to keeping grip glue out of the space between the handlebar and the throttle tube housing? Is there a problem with running the throttle tube at the end of the handlebar rather than 1/8" from the end of the bars?

I use contact cleaner instead of grib glue and it works great. I also run wire on my grips but I road a few times with just contact cleaner as the adhesive and they didn't move. I have no idea why this works also but it has for me. Easy to get on, all the excess just evaporates and it feels solid when it is on there

Yes, you can glue on the right grip without also gluing the throttle. I have two tricks:

1) I find a coin or a large washer that has appropriately the same diameter as the throttle tube OD. I attach it to the throttle tube with scotch tape. I also position the throttle so that it has a minimum axial free play. The coin/washer has to touch the right end of the handlebar but not jam the throttle.

If you run bark busters with aluminium loops, then use scotch tape only in order to seal the end of the throttle. No coin/washer is needed.

2) Find an old inner tube and cut a sheet rubber donut out of it. The ID should be smaller than the throttle tube, and the OD should be larger than the throttle body. Slide the donut onto the throttle tube before gluing the grip.

You can then proceed gluing on the throttle grip. Remove or cut the rubber donut after the due has dried.

I also plug up the hole in the left handlebar tube. This way, if the left grip rips, the dirt/sand won't travel through the handlebar and into the throttle.

I have always dipped grips in unleaded gas then slip them on - it is less aggressive than contact cleaner - when it dries the grips adhere well - I also safety wire grips always

Great forum! I lined up the end of the throttle tube with the end of the handlebar and used Scotch tape to close the end of the throttle tube. I would have never thought of the rubber sheet donut @Phillip!! I cut one out from an old tube and it worked like a champ and blocked excess grip glue from getting into the throttle housing. The grip when on perfectly....and my throttle tube spins without any restriction. Thanks everyone for the tips and tricks!

I use clear spray paint, except for on the alta last time I used grip glue, had the same problem you did. back to clear spray paint from now on. ps. I may try the contact cleaner. pss. I only used grip glue on the alta because I tore 2 right grips trying to mount them. I like these wonky old emgo grand tourismo grips, they're thicker in the middle than on the ends and have air pockets in them. I know, I'm old and I like them.

I have always used contact cleaner. To remove, stick a small screwdriver along the bar when removing. Slip the contact cleaner tip down as far as it goes and as you pull back, spray. With a twist, the grip will slip right off.
