Kroony

On my 1300 I have some spotlights on a light bar. they are pretty loose and will rotate 180 after about 2 min of riding. so i got some time to fix it the other day to find this Allan screw with a wire coming out of it. the wires were run though the light bar before they were terminated as they dont fit though with the lugs on them. so i have to tighten it with the cable in there :S. I have tried to get a flathead screw driver in there, with no luck. I have some old Allan keys that i will try angle grinding a grove in on the weekend. Perhaps im missing something. thought someone here might have a simple genius idea for me.

1st off hi all. im Kroony from Australia I have a XVS 650 and was doing some cleaning on the weekend. I decided to take off the air filter cover and see if the air filter needed cleaning. When i took the cover off a larger blob of oil fell out that was sitting in the cover. Unfortunately is was the last thing i did so after hours of polishing all the chrome under it it got covered in oil. I was just wondering should i be concerned that oil is somehow coming out of the air intake? its done about 14,000k and this is the 1st time i have ever taken the cover off, i got the bike at 9,000 and im not sure what happened b4 that. Any help would be awesome thanks?
