You could install a vacuum pump from a car i think volvo???

Even simply a reservoir would improve things (assuming vacuum is the issue)

Just found this in the MCC Troubleshooting manual:

9 Cruise will not operate at higher speeds (above 80 kph / 50 mph)
Speed sensor test / gap too small
Too many magnets installed
Incorrect calibration/perform speed calibration*
Check diagnostic stop codes (see next page)

* Was this even done? See page 11 of the TS guide and page 16 of the Set-up/User Guide (below)

Speed Sensor Pulse Rate Calibration

• Turn the ignition switch OFF. Press and HOLD the RES and ON-OFF buttons, turn the ignition switch ON,
HOLD THE BUTTONS UNTIL THE SWITCH INDICATOR LIGHT COMES ON GREEN (a few
seconds), then release the buttons. The cruise control is now in speed pulse rate calibration mode.
• Ride the bike at 70 kph (45 mph) and hold the speed STEADY. The GREEN indicator light will be flashing as you ride the bike. The flash rate will vary with the bike’s speed and the frequency of the pulses coming from the speed sensor, so the flash rate may be very slow or very fast or anywhere in between, in some cases it may be so fast you cannot see the flashing except at low speeds.
• Press and release the SET button once. The indicator on the switch will change to RED for two seconds and may flash yellow during this time. The computer will record the pulse rate of the speed signal. Hold the speed STEADY at 70 kph (45mph) for two seconds until the red light goes out. The light will resume flashing green from the speed signal after the red goes out.
• If you are not sure that your speed was correct or stable, adjust you speed to 70 kph (45 mph) again and simply press SET again. Each time SET is pressed the speed pulse rate will be recorded and saved overwriting the previous setting.
• Stop the bike and turn the ignition switch OFF, DO NOT TURN THE IGNITION OFF BEFORE THE BIKE HAS STOPPED MOVING.

This completes the speed signal pulse rate calibration.

Access stop codes
After cruise control will not enage or disengages, press and HOLD the ON-OFF
button for 10 seconds.
Red light will flash to display the stop code.
The Trouble shooting guide** has a full description
of the Stop Codes and what they mean
Press the ON-OFF button once or twice until red
light stays on again to use the cruise control

** See page 4 of the TS guide for the codes

Thanks guys,

Received an email response from Tony at McCruise. Will be doing the test on the slab this weekend.
Tony was very helpful on the install, although I did bug him a lot with questions so I would not screw up

I don't know if you have the option -- we do it in the Air Force when working on fighter planes and bombers -- having a second set of eyes to review your installation, can be really useful.

That's cool Paul, I never new the USAF put MCC on fighter jets too... I bet most pilots forget to tap the brakes, they hate slowing down.

Remember during your install Rick you were asking about the vac connection and I suggested using line common to all three TB'S (pipe B) but you opted for single TB line (although I acknowledge this is what MCC recommended)

Recognize you have less vacuum when throttle is wider open (& reciprocally of course) - so you might be marginal & those wider openings (at 70 & 75 vs 65, where it works) are enough to reduce it beyond requirement.

A quick test would be to close the throttle momentarily at those higher speeds and see if it engages more readily.

Note that you also be sure your hoses are a good tight fit, and not leaking to atmosphere.

It is on line B between 2 and 3. That is where RonTTony recommended .

After making that post earlier, then reading the TS guide, it sounds more like it could be the speedo cal per my last post - did you do that cal Rick?
It specifically relates to (non) engagement at higher speeds

Incidentally I am well impressed with MCC's documentation - they have a LOT of detail in there.

Finally able to get it out today and run the recommended test from Tony at McCruise. Tried to duplicate what happened setting it at 70, no issue so I reset at 75 and it still did not cut out so I bumped it up with the set button increasing the speed a couple mph at a time, then it cut out. The error code I received was 9 flashes which seems to indicate that I have to redo the speed sensor pulse rate. Sent an email to Tony and will wait for his confirmation. No desperate need to get it done today. Ginger has cut down on my riding time this year...

 

[DEcosse]

Did you just try the speedo cal procedure Rick?
It looks really simple ........
And if you haven't done it yourself I would almost guarantee your installer did not either

 

[vanguard138]

No, had some other shot that needed to be done this pm. Tomorrow pm looks good so far. Yea, it does look easy. I did about 90% of the install and was pestering McCruise with a lot of questions even though I was pretty sure I knew the answer. Being a retired Chief Accountant and Chief Budget Officer I am a bit analysis retention and tend to question a lot when I do something the first time. SO I let my Triumph tech finish it to elevate the frustration. None of this install was difficult, other than my doing it the first time and wanting it PERFECT. One of my faults.
