BJB Posted March 20, 2009 Share #1 Posted March 20, 2009 I have an '89 Venture. If I set the cruise at about 100KPH, it will eventually settle in about 107KPH. However, after losing a bit going uphill, on the downside it really speeds up. So much so that I have taken to hand cranking the throttle back so as to keep the speed down. If I don't it seems to hold that high speed quite awhile, and eventually I would have to reset the cruise again. Also, there have been a couple of times where it is like the cruise doesn't know where it is, and senses it is REALLY below speed. This results in the throttle opening up almost wide open. Not sure if it would correct itself as I always cancel the cruise, and then reset. So, any ideas what or where to start? Is it a sensor, or the whole cruise control module? Replacement? Thanks for looking guys. Link to comment Share on other sites More sharing options...

5bikes Posted March 20, 2009 Share #3 Posted March 20, 2009 1. Lubricating the cables using light oil. Take cap off the electrical components next to grip, 2 screws, pour oil in/under pulley. 2. Make sure there is 1/8" free play at the hand grip. 3. Look at linkages at carbs do they move freely? If the throttle cables/linkages have even a little drag the cruise does not function properly.

Marcarl Posted March 20, 2009 Share #4 Posted March 20, 2009 Vaccum leak or maybe a blockage it the intake manifold,, or a kink in the vaccum line. Link to comment Share on other sites More sharing options...

Thanks for looking guys. My '86 acted similar to this when I got it. What seemed to work on mine was I had to clean the sensor that is mounted on the back of the speedometer. The sensor is in a small rectangle plug with 2 wires going to it above where the drive cable enters. Carefully remove the sensor from the housing and clean off the dust with a soft cloth then re-install. Mine has been working like a charm since I did this. If this does not work I have a nearly new cruise control module with about 100 miles on it I tried before cleaning the sensor. I paid $100 for it and I'd let it go for half that.

GeorgeS Posted March 21, 2009 Share #7 Posted March 21, 2009 Check the Switch on the clutch handle. It fits loose, thats how Yamaha made it. This can cause the Cruz to dissengage. I made a small bracket to hold the Switch tight up against the mounting point. That cured it on my bike . Be sure to check that hose from the pump in the right side faring, that runs to the Actuator on the left side. Link to comment Share on other sites More sharing options...
BJB Posted March 21, 2009 Author Share #8 Posted March 21, 2009 :Venture:BJB that new venture would fix that cruise real good, just an idea:big-grin-emoticon: Thanks Al. I had the same idea all winter but since the 89 didn't sell I may as well get it ready to go. Won't be long now till ridin' season. Thanks to all the rest for the ideas. I will try them all.

bobcat Posted March 21, 2009 Share #9 Posted March 21, 2009 The cruise control on my 86 VR seemed to have a mind of its own...At times it wouldn't engage other times it would...I changed the bushing in the clutch handle, changed the vacumm hose etc and it would work for a while then go back to is old habits....Sometimes the bike would speed up other times it would slow down....Finally I reached the end of my rope and bought a $35 friction lock device called a Vista Cruiser from JC Whitney....It takes some getting use to but it works great and because its so simple in design it works all the time....
