Vulcan Quick Turn Throttle Kit

[gv550]

Dave Shellenberger (dshelly on this forum) provided me with his throttle mod ring for evaluation on my 1700 Voyager.
Quick-turn throttles, also known as '1/5 throttle' or simply 'throttle mod' have been around for many years primarily for sport bikes but these are too small for the larger 1" handlebars used on cruisers. Dave has made a throttle mod ring to fit Vulcan 1600 and 1700.
This ring is just beautiful, CNC machined from 6061 aluminum, has a concave groove to keep the cables centered, 3 countersunk holes, and fits perfectly on the stock throttle tube. He also provided 3 screws and brief instructions on the installation.
I read the instructions and gathered up the required tools, and it took me 25 minutes to complete. I have had my throttle apart a few times to lubricate the cables so it was not the first time I was in there, or it may have taken a bit longer. The 1700 is a bit different than earlier Vulcans in that there is a chrome cap on top of the housing that holds the 2 halves together, remove that along with a clamp screw on the bottom. Also remove the cable clamp screw from the bottom.
Simply slide the ring in place and use it as a pattern to drill and tap the center hole, install the screw and repeat for the 2 other holes. Drilling and tapping the plastic was very easy, I didn't even use a tap wrench, just turned it in with my fingers. It was a bit tight to get the cables back on due to less slack but they will go on.
Since the ring is held on with 3 screws, it can be removed and put back to stock condition if desired, or reused on another bike.
I compared the throttle movement before and after, it turned about 95 degrees stock, and about 75 degrees with the mod ring installed. I also wound a string around the throttle and pulled it with a spring scale, 6 lbs to get it to turn stock and 8 lbs after the mod.
Then for the test ride, 80 miles at 80F in the Florida sunshine , I really like the quicker throttle response and after 2 hours without using the cruise control I could not feel any extra stress on my wrist from the added load. My stock throttle tube was worn and had a fair bit of end-play but adding this ring reduced that and it feels new again.
I understand Dave plans to make this kit available soon, and maybe a turn-around service if you want him to install the ring on your throttle tube, I'm sure he will chime in with those details.
