loosen throttle lock.loosen return cable some.adj pull cable until slight freeplay without binding then adj return until you get binding then loosen until binding ceases through bar travel from side to side.
One thing not mentioned is cable adjustment. If you have the return cable too tight, it places enough tension in the system to stop or reduce the return. It should have a hair slack in it. If the grip assembly has been r&r at some point check to make sure it's not slipped on too far. This can cause the end of the bar to place pressure in the back side of the grip. Look for about 1/16 in and out free float on the throttle grip to rule that out.
As mentioned, lubed, tension wheel backed off, and no kinks or sharp bends in the routing. Test return at full left and full right on the bars.
Yeah, I guess I'm just going to have to deal with it. The idle cable I think is too long. Its at its shortest length and I think I need to go shorter. Anything in the opposite direction and it doesn't return at all. I'll hope that vacuum at idle will help it close that last small percentage.
My 08 had this problem when I bought it used. One of the cable housings had come out of its home on the throttle body. I loosened the cables and put the end where it belongs. Readjusted per the book and all is well. Snaps shut immediately.
Hey guys - sort of embarrassed, but I think the issue is due to having the wrong cables. I have a 2011, so I ordered a 2011 set not thinking. I swapped out front end for 2012 which has 2" extra length. I think as soon as I get the new cables on I'll have enough adjustment available that I can properly adjust them. Stay tuned!!!
Anyone need barnett stealth cables???? Installed and never ridden!
UPDATE: I got the new cables, but still had the same issue.
FIX: SILICONE SPRAY THE INSIDE OF THE CABLES
Unbelievable. These were so non-lubed that there was a squeak when twisting the throttle.
To my surprise when I tried the throttle this morning, it was smooth as butter and SNAPPED back for the first time in years of ownership!
It's amazing. Even though the cables are "lubricated" from the factory, apparently, they miss a few of them. I adjusted the cables, reassembled the housing and bam. Thing works great! The throttle never snapped back from the day I got it until now.
