I forgot: When sliding the grips slowly up the bar, twist them around in a circle at the same time. You get a more even spread of glue on the inside this way. As they get all the way on, you want one row of rubbers directly under the middle of your palms as you would sit comfortably on the bike and reach for the grips. The other row of rubbers will be under the last two joints of your fingers on the other side.
If you didn't get the Iso Kury throttle boss for the throttle side, you should. Using the 4-screw end caps, position that boss flap up at about 10 o'clock (looking at the end of the bar), the idea being that when twisting the throttle down to run the bike at about 45-60 mph (usual cruising speeds), you can slide your hand down the grip and hold an even speed with your palm (at which point, the boss is now sitting at about 7-8 o'clock). I see they are making some larger throttle bosses for the Iso's now. I have the original smaller one (below). I would not want the boss to interfere with my usual higher grip on the throttle when cranking and banking and going through the gears.

Finally, Kury sells (1500) Valk specific Iso grips that are like 6 1/4" (extra) long, and they come with spacers to drop down in the grip to lend rigidity to the ends, if they are positioned beyond the handlebar ends a bit (and I think they do on the 1500, leaving the control boxes above the grips in the stock position). But regular one inch bar
universal Iso's (5 1/2 or 3/4" long) will also work and need no spacers. I don't know which you bought.
With the longer grips, the throttle boss on the end will not interfere even with the biggest hands. But if you got the 5 3/4" grips it could possibly interfere with large hands, and if so, the solution is to turn the boss around and aim it out from the end of the grip, rather than the usual up-the-grip position (like in the picture).
I think I'm done.
