Always lamenting the longer throttle on the Fzs1000 compared to the Fzs600 I fixed it today by fitting the 2006 on R6 Throttle tube today. Yamaha part number is 2C0-26240-00
Much better now and more like the 600 when blipping the throttle now on down changes. The 1000 throttle tube has about a 36mm diameter cable section as standard whereas the R6 one has about 40mm diameter cable section. The early R6 is too similar to the FZS1000 to be worthwhile.Fitting was straight forward enough, lift the tank, get as much slack on the cables as you can. Loosen the lock nut on the rear cable and wind it all the way back. Wind out the adjuster on the front cable to allow you dislodge the front cable from its the mounting. Undo the knurled lock ring on the cable near the front brake lever and wind it back all the then screw the adjuster back all the way. Remover the end weight. Remove the two Allen bolts on the switch gear (longest one to the front. Lift off the kill switch section and then remove the cables rear one first. Rotate the tube forward(anticlockwise) and undo the front cable at the bottom. Install the front cable first on with the tube cable holding section down and put the front cable into what seems like the wrong hole the rear one as you look at the tube. Now rotate the tube clockwise to bring the cable mount to the top and install the rear cable. Put it all back together locating the switch gear in the hole if using the original bars, ensure the black disc is on the outside of the switch gear and replace the Allen bolts tighten them up.This is metal into plastic so do not over tighten them.
At the carburetor side relocate the front cable and tighten up the adjuster. Check the slack on the throttle and turn the bars full left and full right checking the slack each time. rear side was a bit more fiddly as I need to get maximum possible slack here. Pushing the cable down on the mount and using a fine screwdriver turn the lock nut anti clockwise as far as possible literally wiggling the throttle cable while doing so to get the maximum turns. Tighten the locknut and check the slack again bars straight ahead and full lock left and right. Any slack can now be taken up this the cable adjuster near the front brake lever.
