I ordered the 6235 ISO Grips and the 6250 Throttle Boss. The 6235 comes with 2 grips, glue, instructions, and a small plastic tube about 1.5" long and 1" in diameter. NOTE: The new grips do not come with an allen wrench to remove the end caps.
Heres a picture of what you will end up with afterwards just for reference (note, old clutch grip is not in picture, I had already thrown it out)
Throw out the 1.5" plastic tube, it is not needed and just confused me at first. I also threw out the glue and used Gorilla Glue. I wanted a little more time before it set.
Throttle Side NEW Grip that has a plastic tube fixed into it.
1) Tap off chrome end cap. I used a flat blade screw driver and hammer and very lightly tapped. It comes off pretty easy.
2) Loosen the throttle cable adjuster and remove the 2 screws in this pic:
3) Remove the lower half of the starter switch cover and set aside
4) Remove the Philips head screw to completely remove the starter switch assy (NOTE: I do not have a pic of this but it's pretty easy to figure out once you complete step 3)
5) Lift off the starter switch and push to the side
6) At this point you will see where the throttle cables hook into the throttle. If you look at the second pic at the top of this thread you will see the end of the throttle tube. You should be able to pull the throttle cable out of the hooks. I used a small pair of smooth needle nose pliers. If you loosened the cable up in step 2 this should be pretty easy. I removed the rider side first and then the brake handle side.
7) Remove the old grip.
Slide on NEW Grip
9) Re-hook the brake side cable
10) Re-hook the rider side cable (this one was a bit of a pain but if you take your time it should pop back in)
11) Re-assemble the starter switch assy. 1 screw, then the 2 screw cover plate on the bottom.
12) Re-Tighten the throttle cable.
At ths point I installed the Throttle Boss.
1) Remove the NEW grip end cap via the 4 allen head screws
2) Install the Boss between the handle and the trim ring.
3) Using the 4 longer screws (provided with the boss) lightly tighten the end cap
4) Adjust the boss to a comfortable position
5) Tighten the 4 allen head screws
Step back and compare the old vs new:
Clutch Side, NEW Grip that does not have a plastic tube in it:
1) Cut off the old grip with a sharp knife.
2) Using a flat blade screw driver or a large open end wrench and a hammer lightly tap off the end cap. It comes off pretty easy so just tap it off.
3) Remove the chrome trim ring
4) Clean off the old glue. I used a little alcohol and some sandpaper.
5) Remove the end cap from the new grip. Use an allen wrench and remove the 4 screws from the end.
6) Apply glue to inside of NEW grip. You should apply the glue to what will be the "inside edge" of the grip so that as you push it on the glue slides down the rest of the inside. I used Gorilla Glue so that it would give me a little more time to set it on.
7) Slide grip on and align the rubber where you want it. I set the rubber grip on the top and bottom, it felt most comfortable and matched the alignment of the throttle side.
Wipe out any excess glue from the end of the grip
9) Re-install the End cap using the 4 allen head screws.
Stand Back and look at the new grips:
EDIT: Apologies to anybody looking for the pictures. I haven't been here in ages and had killed the old host I was using. These should be good for a long while.
