Anyone know what mods are needed to put a slow action throttle on my rev 4

Hi Neilnh. I tried the domino slow action tube and its way to slow, go with the white tube [fast action ] domino .You can shorten the existing cable , or put in a cable spacer like they have on an amal 80/200 throttle . Hope this helps Martin

cheers for that another project for this weekend coming up

I did the same. It works but is very slow..... you almost have to move your hand to get full revs. Now back to the std throttle with the acceleration ramp filed off it.
