I've been asked on a few occasion for info on how I accomplished the installation of a Rostra CC on my AE. A thorough search on the web will provide details regarding wiring and so forth, The biggest challenge I believe is the installation of the hardware.
This is how I did it....
I placed the control unit in the space between the rear seat and rear cowl. Its a tight fit and there is contact with the seat but the unit settles in without any problems. The pic shows the cable exiting to the right of the bike, the final installation has it exiting to the left.
The connection to the throttle.... the nut (use loctite) on the right needed to be filed slightly for clearance with the cable when full throttle is applied. Be sure to check for any interferences during full throttle rotation.
I used a metal wheel for a sliding screen door and carefully placed L brackets to redirect the chain... lots of fine adjustment needed here. The L shaped piece on top ensures the chain stays in the wheel groove. Not shown is a loose fitting piece of plastic tubing that the chain runs through between the wheel and throttle connection which keeps slack chain (if any) from possibly hanging up on something. My biggest concern through all of this was eliminating the possibility that the throttle would get stuck partially open for any reason. The bracket for the rubber covered gizzmo adjacent to the wheel needed to be adjusted to provide clearance. Note use of self-locking fasteners.
Cable is led rearward. ****VERY IMPORTANT**** The fuel hose running from the fuel tank needs to pass UNDER the cable. There is room in the "valley" just forward of the air box for the fuel hose to reside with out contact with the cable. The fuel hose has a factory installed protective rubber sleeve, I wrapped this with metal tape for added chaff protection. the last thing you want (next to a stuck throttle) is the cable sawing its way through a pressurized fuel line. I've checked for contact several times since installation....no problem.
Rough cut out for the heat shield exit.
And finally my chosen method for controlling the thing... a pair of Radio Shack micro switches.
Regarding wiring - I have the unit powered at all times, no on-off switch. I used a Centrodyne Pulse Divider between the ECU and the Rostra unit. Search the web for details.
In closing - I have been spoiled by the cruise on my K1200LT and will not do without it on any bike I ride for hours at a time. This installation has worked flawlessly for 11,000 miles. I do inspect it regularly for any potential problems. I think the weakest point is the chain itself...so far so good.
Warning - screwing with the throttle system of a high powered motorcycle is serious business. The material presented above is intended for information purposes only. It is not intended as professional advice and should not be construed as such. So there.
