Dynamo cover gromment leaking

17 Dec 2017 10:47

The left side cover which covers the Dynamo on my 900 is leaking. The grommet the wires go through is known to leak at some point. The fix is a new grommet, cut and re-solder the wires back together after running them through the new grommet. Not my idea of a good time...simple enough but I really don't want to cut wires. So I was thinking of taking the dynamo cover off and hosing everything as in grommet and wires with brake clean. Then slather the entire grommet/inside wires with Honda Bond and put back together. Or should I just bite the bullet and replace the grommet? If you have not used Honda Bond before it is pretty runny compared to RTV. I know some of you Z1/KZ owners have dealt with this problem. Thanks, my left boot is well oiled. Tim

I tried everything finally replacing the grommet. I also used crazy glue on the woven sleeves over the wires to keep them from wicking.

You can do it that way but the wires are covered with cloth. I had to clean with brakeclean and dry multiple times then soaked the area with form-a-gasket and let it soak into the wires. I also used silicone between the grommet and housing surface.

I cleaned the wires with dish soap and water pulling them back and forth getting "ALL" the oil off of the wires and grommet and let everything dry real good, maybe a day? then I worked (Ultra black RTV high temp sealant) into the wires and inside the grommet and let that sit for a day before reinstalling.

50,000 + miles and still holding.

I was told on another forum the grommet has slits in it for the wires. If so that would be great. But since out of the 3 Z1's I've owned I have never had to mess with it before. So I don't know.

I bought a impact driver with a #3 Philips. Was thinking about hitting the tip on a grinder. I have S/S replacement screws on hand. Tim
