I'm getting a buzzing in the front and back head sets, I can turn the intercom down and don't hear it. Dont get it in the radio though.I put a filter in the rear head set cable but didn't seem to help, I also put a motor and frame ground on that seemed to have worked for a few months but now its back, grounds seem to be tight.Any new ideas?

If you have just the front headset or just the rear headset connected, do you still hear it? Do you hear it if the bike is on and the engine is not running? Does it change in frequency with the engine speed?

Also, try shutting the cruise off. If no noise then, you might need to shield the cruise control unit!

I might suggest checking all your connections to ensure that none are lose, dirty, and/or in need to cleaning. Have you pulled your top shelter recently and disconnected any of the connections? Easy to check.

I don't seem to get it with either head set unplugged, but do with both, front and back, does change with engine speed, turned cruise off no differance, engine off no noise,had the shelter off several times doing air filter changes, I believe I had it before any removals, also cleaned the head set connectors.

This is possibly a ground loop or grounding problem. Do you have any aftermarket electronics added to the bike? Phone plugged in, MP3 player, that sort of thing?

Pop,

I am not an electrical guru but I do know that there is a lot of value in checking the grounds as noted and don't forget the main one off the battery.

If all hookups are good then you might try double checking the settings on the intercom system. If all else fails you might contact Larry M at his website: http://www.wingconnect.com/

Check the contact info for a phone number and call him, OOPS, I think he only accepts emails.

Thanks for all the info, I'm still working the problem, maybe I'll just keep the volume turned down, when were not talking.

I would have hoped newer models had a better intercom solution but if you're getting static or alternator whine in your headsets you have at least an issue with the system ground points. Mother Honda used locktight on the ground point bolts as well as leaving paint on the engine block where the grounds are secured. There is one (G2) under the right side cover right near the drop down of the seat and another (G1) under the aft overhang of the gas tank (PITA to access). Cleaning them out with a thread tap and sanding the paint from the contact area often proves worth the work and cleans up the electrical ground. Also replacing the locktight gummed up bolts with clean ones would be additional benefit. When you re-secure the ground wires use a star washer against the block. Now expanding on a prior posting, if you tap on the housing near your gas tank and can hear it in the intercom that's the radio's intercom circuit picking it up and LarryM at http://www.wingconnect.com/ can make circuit upgrades for that and a few other radio issues (AMP power, etc.) I heard he has a great turn around but of course your bike is down during the time you have the radio sent off for work. Definitely worth it if you're parked for the winter.
