Cruise Control Conversion

Postby jhaan92 » Thu Jan 13, 2011 7:59 pm



I know that I am new to this site, but with myself and my roommate owning a pair of GL1200A's, this is a question that we have discussed often, so I thought that I would pitch it to those that know best. I have surfed this website a few times, but never got around to signing up (what is WRONG with me?! :oops: ).

Can you take the cruise control assembly out of an 86-87 SE-i and make it work in a 1985? I know that they use 30MM carbs in 86-87 with an accelerator pump, while out 1200's use 34MM carbs. Would this be a problem? I took a look at some pictures, and it seems that the layout of the carbs, the fuel pump, and other various items seem to be in the same location, so I would think that, theoretically, the assembly should fit. My biggest concern is that with the smaller carbs, the cruise might not be able to maintain speed.


Geez, I need to stop being so deep sometimes... :mrgreen:

Yes only the 85-86-87 I & A are carburated. 85-86-87 Ltd & Sei are injected.
That being said I think it would be a nightmare to try and put a Ltd or Sei cruise control because of all the electronics involved. Other wise I think many would have already gone that route.
I believe the 87-A could be had or came with cruse. Again there is a control module and all the other stuff, again I think makeing things tough.
I think the Wingman or others have been able to convert automotive cruse controls to their Wings.
Good luck and let us know if you get-r-done :geek:

Enjoy the ride. They are all good, just some better than others.

Maybe. It doesn't look like the physical cruise control vacuum assembly would be too hard to get lined up, but I do think you're right about the electrical. I'm looking at the schematic, and there is an extra voltage rectifier/regulator(?) Interesting. It was just something that we had been kicking around. I don't think that the cruise assembly off of the 85 LTD would fit, with the fuel injection and whatnot. This will take some time, and some extra money to get going. A project for next winter perhaps. Right now, I'm just working at getting the bike restored from the ground up. Not many miles on it, about 52,XXX. Paint is tired, gaskets are starting to leak, and the clutch needs to be replaced (or so I think). It will take me about a month to get everything done, but I think that when the dust has settled, it should look real nice.

Anyway, I don't see any reason as to why this couldn't work, but I do believe that there will have to be some modifications to the electrical system for this to work properly. I'll have to look around to get an electrical schematic of the 87 Aspencade and go from there.
