Ok!
What can you do with a motorcycle and $2.00?

Build a throttle clutch.
Yep, for about 2 bucks you can have a throttle clutch on your Roadie.

Here's what you need ...

About a foot of  vacuum hose and 3 or 4 wire ties. That's it. Take your bike to your auto parts store and find a piece of vacuum hose that will sit snugly between the hand grip to starter switch housing. Refer to photos 1 through 4.

You might be wondering why it's referred to as a Throttle Clutch rather than a throttle lock.
With this setup you can still adjust your throttle setting. It holds just tight enough to keep 
the throttle where you put it and loose enough to change the setting without strain on your hand.

To engage simply reach over, grab the hose and lightly pull straight down. Now adjust the throttle to the desired HIGHWAY SPEED.

DON'T USE THIS IN CITY TRAFFIC, YOU'LL KILL YOURSELF. SEE DISCLAIMER BELOW.

To disengage, grab the tail and pull back and towards you.
Now go cruise the highway and enjoy yourself without the right hand cramping on those long hauls.

Disclaimer: I AM NOT RESPONSIBLE FOR DAMAGE TO YOUR BIKE IN ANY WAY, SHAPE, OR FORM. I AM NOT RESPONSIBLE FOR INJURY OR DEATH TO YOU, YOUR LOVED ONES, THOSE YOU HATE, OR ANYONE ELSE THAT YOU KNOW OR DON'T KNOW FOR THAT MATTER.
THIS ITEM IS NOT TO BE USED IN TRAFFIC.
IF NOT USED PROPERLY OR ABUSED YOU MIGHT KILL YOURSELF.
IF YOU ARE NOT SURE OF YOUR CAPABILITIES, DON'T USE THIS DEVICE.
IF YOU ARE JUST NOT SURE, DON'T USE THIS DEVICE.
IF YOU HAVE TO E-MAIL ME AND ASK, 'WHAT IS A THROTTLE LOCK', DON'T USE THIS DEVICE.
I HOPE I HAVE COVERED ALL THE BASES IN THIS DISCLAIMER.
IN SHORT, I'M NOT RESPONSIBLE FOR JACK S#IT, USE AT YOUR OWN RISK.
PERIOD.
