Headlight Adjustment Question

I recently replaced the stock headlight bulbs in my '97 Viffer w/Hella halogens. Once I eliminated the mounting tabs that weren't in the right place on the bulb base plates, they seemed to fit fine. I also put new tires on at about the same time, a different Dunlop model than I've used before (Roadsmart). At least one of these two changes seems to have negatively affected my headlight beam. My lights now point down even further than they did before, so close-in as to be totally useless on low beam, better but not great on high beam. Moving the adjustment screws behind the lights has no effect. This problem has existed since I first purchased the bike a few years ago, but is worse now than before. My bolt-on PIAA's are the only way I can ride safely at night. Anyone have a suggestion that will get my headlight beams adjusted back up where they should be?

A very old website but the answer to your question

H4 modification to VFR750 headlight assembly

Best...

 

Thanks for the link! Never saw that one before.
