After doing some research I found that I wasn't the only one who found that the VFR when initially rolling on the throttle can be a bit snappy and abrupt (very on/off). At first I thought this was just me not being used to the bike, but after almost a year of riding I found it to still be snappy. My FZ6 was similar and as it turns out this seems to afflict the majority of fuel injected bikes.

G2 Ergonomics has come up with a redesigned throttle tube to help eliminate this initial throttle snap. The Throttle Tamer has a cam with a reduced radius initially, which requires a slightly farther rotation to achieve the same carburetor or throttle body opening position as a stock throttle.  This virtually eliminates the jerky “throttle snatch” especially evident in modern fuel injected street bikes.  The radius increases or “ramps up” after ½ throttle to keep overall rotation requires to reach full throttle at or near stock rotation.

Some info about the G2 Throttle Tamer:

• Machined from 6061 aluminum in the USA!
• Self-lubricating Delrin bushings at each end of tube eliminate aluminum-to-aluminum contact and provide an ultra-smooth feel.
• Included cam is removable and can be replaced with alternate cams (sold separately) to fine tune control.
• Fits inside the stock throttle housing to stock cables.
• Works with all known aftermarket cruise controls.
• Installs in minutes!

Now, I had three minor issues when installing my G2 Throttle tamer:

1. Heli-Bars - I have Heli-Bars and the OD of the Heli-bars is slightly larger than stock handlebars. The G2 Throttle tamer would barely fit on the Heli-bars and was very hard to rotate (NOT what you want). I had to sand off the powder coating on the Heli-bars to get the G2 to rotate freely and smoothly.

2. I found that the G2 Throttle tamer was still just a bit too long. G2 said they had addressed this issue, but I found I still had to removed arpx 1/4" off the end.

3. I was also installing a set of Oxford Heated Sport Grips and I found that the G2 Throttle tamer OD was +0.040 thicker than the stock throttle tube. The Oxford grip would initially not slip on over the thicker G2 Throttle tamer. I used a Dremel and smoothed out the initial ridge of the knurled area on the G2 tube.

Here is a close up of the G2 Throttle Tamer cam.

Installation:

IN order to remove the throttle cables from the factory throttle tube I followed these directions given to me from a member on VFRD Forums:

Lift up tank.
Loosen locking screw on upper throttle cable on throttle body (left side of airbox, low).
Slide upper throttle cable out of metal bracket.
Pull cable to the rear of bike and unhook the cable from the throttle body cam.
You should now have plenty of slack in the hand throttle.

Do the opposite to reattach, and make sure you readjust the throttle play using the adjusters on the handle bar.

After sanding off the powder coat on the Heli-bars and cutting off about 1/4" off the tamer tube, they slid right on.
