Hey Britman, I have those Kury.. grips (flame style) & installed them myself. Why would you think the throttle cables would be affected? You need to decide if you would want to go back to the stock grips in the future cause you'll need to cut the nibs off the stock grip sleeve and this "may" impact the ability of the stock grip to "hold" if reinstalled.
Simply "peel" the throttle grip off the throttle sleeve (after you have removed the vibration dampener weight from the handle bar end). The instructions say to cut the old grips off but I choose not to approach it that way. With a utility knife, trim all the little nibs off the sleeve assuring each one is trimmed smooth with the surface to allow the new grip to slide the best it can. Some of the larger nibs will come off better if you take a little at a time in stead of trying to remove the whole nib at once. Getting the Kury... grips on the sleeve is kind of a pain, you have to work it on a short distance then back off a fraction of the "gained" distance to allow the rubber parts to straighten up. Then advance a little more, back up, advance more, back up. Repeat until installed. You could use a solution of soap & water to slicken up the surface, but I didn't. The left side is easy. In fact the hard part is getting the Kury... grip to stay on. I choose "not" to use the glue provided. I was afraid I'd have to destroy the grip to remove it if I was not satisified with them and could not see cutting the $85 grips.
Note: the Kury.. grips are longer than the stock grips (about an inch) and will hang off the end of the handle bar, unless you can figure some way around that. I can't recall specifically why I did not persue the matter but as of yet, I have not. Surely the small tubing spacer has something to do with allowing the full installation of them, just can't recall. Let me know how it goes, unless you've already completed the task. I'm a little slow at responding to your question.
See ya.
