I've installed 6 or 7 cruise controls over the last 20 years. All were Audiovox CCS-100's except the last one done a year ago on my Gen1 FJR (McCruise). The other bikes were ST1100's (3 or 4 times), VStrom 650, and KLR650. In my opinion the CCS-100 installations were easier than the McCruise.
It is probably not a fair comparison because the McCruise I installed on my FJR was not custom made for the FJR. It was one of the earlier models that was made to install on a 1998 ST1100. It did not have a speed sensor connection to a coil wire but used a hall effect sensor that monitored rear wheel rotation. That part of the installation was not too difficult, I was able to reshape the bracket that the pickup coil mounted on and attach it to the rear axle pinch bolt. 2 small magnets are inserted into 2 of the rear rotor allen bolt heads. (later models utilized 6 magnets)
The wiring harness was completely different because of different component locations. The Computer was placed under the tail section just in front of the tail / brake light assembly (same location as ST1100). The wiring to the brake light switch and the speed sensor was relatively simple.
The tricky part of the install was figuring out where to mount the cable interface unit (CIU) and the vacuum servo. There are 3 cables to the CIU, one from the throttle "pull" cable, one from the vacuum servo, and one going to the throttle bodies (connects to the place where the throttle "pull" cable was removed. I experimented with different locations for the CIU and ended up placing it under the fuel tank on the left side. This location could not have been used if the hoses / valve for the PAIR system were still present. I used the nicely machined plates from Dave at WynPro to free up some space between the valve cover and the fuel tank. The connections to the CIU were a little tricky because the orientation of the unit in relation to where the cables go was different between the ST1100 and the FJR. So new holes had to be drilled and tapped into the plastic CIU housing. This would not be a problem if you bought a unit from McCuise that was designed for the FJR.
I mounted the vacuum servo under the seat where there was just barely enough clearance because of the ABS unit that is just below the storage compartment.
There is a 3 position switch on the computer for sensitivity (low, med, hi). I ended up using medium which maintains speed within 2 or 3 mph without harsh engagement (which happens in high). Low works ok but speed can drift 4 to 6 mph in hilly country.
I initially mounted the control switches on the left handlebar under the clutch master cylinder but it was difficult to reach the switches so I removed the assembly and simplified the wiring using micro switches from my "parts stash" (former computer tech). I put the switch for "set / accelerate" above and to the right of the left handlebar grip and the "resume / decelerate" switch just above the kill switch on the right side.
I added a safety relay to remove power from the unit when either brake is depressed and a switch on the clutch lever to disengage the cruise as soon as lever moves. I pull vacuum from all 4 throttle body connectors (with 4 check valves) and fabricated a vacuum cannister in front of the rear shock. I mounted a small vacuum gauge on the dash so I can see when the cruise engages and make sure there are no vacuum leaks.
McCruise tech support is excellent and they helped me out with installation and troubleshooting documents even though I was not the original purchaser of the unit. I also got support from a member on the ST-Owners site who has installed several units on ST1100's
McCruise has an optional servo (motor driven) that is smaller in diameter than the vacuum model which should be easier to fit. Probably costs extra though (not sure).
If I were to buy a new unit from McCruise (unlikely because of cost) I would want to be certain all components were designed to mount on the exact model of FJR that the unit was being installed on.
Sorry no pics were taken of install (but it really DID happen
)
