Take a look at this install. The cruise kit was originally made for 4 wheel vehicles. The car engines make 17-20 inches of vacuum at idle and 8-10 inches with the throttle wide open. The FJR engine pulls ~10 -12 inches of vacuum at idle and only 2-4 inches wide open. Due to the big disparity in vacuum, motorcycle require a vacuum canister to provide some reserve capacity for when the cruise control needs to make big changes in the throttle settings. Do consider buying from Murph or making a vacuum canister.Sweet thanks! So at the bottom it has some options to add to the order, what should I get I know very little about these units.
The Murph's relay will let you have ignition switched power to the cruise control servo.
For bike use, you may be interested in a mounting plate for the cruise control switch pad, there are aftermarket mounts for the cruise control pad which mount on the left mirror hole.
Speaking of vacuum, it is advisable to tap several throttle body sync ports as vacuum sources using check valves to keep the ports from back-streaming.
You will want to pop the cruise control switch pad apart and seal it, it isn't intended for outside use.
First look at the install in the opening link, then you will be able to ask more targeted questions. The install instructions are as good as any (and there are a bunch on You-Tube).
Edit to add:
1. You aren't limited to servo location shown in the how-to.
2. The shown vacuum accumulator is just one way to do it.
3. There are now better fabricated pad mounts available.
4. The hardest part of the install will be drilling and connecting to the throttle stop tab.
I recommend you start there, failing to get this done makes everything else moot.
