I love my "Go Cruise"
easy to install, easy to adjust and easy to use with gloves on, another plus IMO it looks like OEM on my Black F6B.
I did find I needed to adjust my 'pull to open' throttle cable free play as it came from the factory a tad to loose for me, I know Honda likes them loose and I understand why, but as long as I'm getting a complete closure of the throttle body butterfly when letting off the throttle and no pulling on the throttle cables or change of RPM in a right to left lock to lock of the handle bars, all is good. I want no play in my pull open throttle cable. I do tend to run a little more slack is in my 'pull to close' cable.

I better get back on track here...the loose throttle cable had no effect on how the "Go Cruise" performed and was just something I would have done anyway.
I also run the ISO black grips over the OEM heated grips and had no issues with the "Go Cruise" install.
As throttle locks go...."Go Cruise" does that just fine... at a price that is hard to beat.
