Something is wrong.
Been replacing my headlight bulb (H4) with about every kind of bulb i can find.
last one was a bulb made for harsh environments (expensive as fuck)
One tank of gasoline later and that one was out as well.
I have replaced my charging system completely and checked the voltage.
it the highest jump I have had was about 14volts.

But the whole headlight vibrates as fuck.
Some how the bikes vibration gets amplified at the headlight.
It is vibrating bad.

I wonder how it is supposed to be fitted?
Mine are only connected by the two struts that comes from the fork.
(looks like a clamp on the shock leg then two long arms that are bolted at 9 and 4 or clock on the headlight)
the rubber dampeners looks fine to me.
Only one thing that I feel that could be off.
At 6o clock at the headlight I have a big bolt but it doesn't hold anything In place at all more then the nut on the inside.

Should I be connected here as well? I can't seem to find any other way of doing it than the way it is connected now.
if it is supposed to be another strut or fastener here it is long gone.
and I can't even find any fastner on the bike where it should have gone to anyway.

And as said I don't feel that the bike is vibrating more than normal, anywhere else.
but as stated the vibrations are getting amplified tenfold at the headlight.
And I am getting tired of stopping to replace my bulb more often than I fill her up with gas.

Any suggestions?
A picture of all the points where the headlight are fastned to the bike would be great.
(its my KZ750 E1 that I am talking about btw)

Hi
Yes something wrong for sure.
Here are some photos of my 1980 750E1.
In the first you can see the headlight bolted at 3 o clock (matching bolt at 9 o clock) with rubber dampers etc. Also bolted at the bottom to the mechanism that is used to set of=r adjust the angle of tilt.




The second photo shows a close up of the til mechanism and the attachment points. Hope this helps

I suspect the rubber dampeners have dried out, making them not respond to vibration. If possible, replace them, and on the new ones, spray them with Silicone, to retard the drying out.

This was the only parts diagram I could find for you. I don't have a 750 so I don't know how different they are

Most bikes don't have that bottem mount on the headlight.Do you notice a lot of excessive vibration anyplace else on the bike?

No eBay APP ID and/or Cert ID defined in Kunena configurationI don't feel any excessive vibration anywhere else on the bike.
Sure it vibrates but I believe this to be normal since it is an old bike.
I wouldn't rate it as excessive.

But after looking at the photos I know for sure that I have an aftermarket holder.
Mine are in chrome/stainless and looks a loot like these

And they look kind of long when compared to the photos you so kindly supplied JR.
The vibration in the headlight when revving the engine is like holding a hand on an orbital sander and on the shocks I can't feel much vibrations so the way they are mounted must amplify the vibrations somehow.
I have checked the rubbers and have gotten half of the rubbers already (the outer most rubbers where backordered)
But when I compare the new ones with the old ones they feel about the same so I recon they are okay.

I am pretty sure that the both the length of my aftermarket holders and the way they are bolted to the bike somehow creates the perfect amplifier.
I am going to attack the holders with a magnet tomorrow and see if they are indeed chrome.
Hopefully they are polished stainless steel.
if they are they are stainless I will shorten them and re polish and see if that helps.

I am actually thinking of adding some lead in the bucket as well

Any other suggestions on how I could fix this problem?

One thing you may want to do is to use a torque wrench and the specs in the Kawasaki Service Manual and check all the engine mount bolts to make sure they are properly tightened. If any are loose they could cause vibration. Ed

One more thing to my list then
I will torque all the bolts as well then.

I have heard from another source that carb balancing could help some with vibrations as well but it was not long ago I did balance the carbs but will check that anyway just to make sure.

Also possible the H4 bulbs are all junk you are using. My old KZ650 when I got rid of the stock sealed beam headlight and went to a more conventional setup, there were bulbs made just for that motorcycle headlamp replacement sold through motorcycle shops. I could use those bulbs no problem, but I had a negative battery terminal break off one day when I was riding and burned out the headlight as well as 10 or so other bulbs. I found if I went to an automotive bulb, regardless of price, it would last only a few days. So if it wasn't for the fact I knew my electric system was fine, I would have gone in circles trying to determine why "my motorcycle was burning out headlights". Went back to the motorcycle bulb, and the bulb still lights fine to this day. Of course this was 30 years ago, so may or may not be the case now, but a possibility, because I just don't believe your motorcycle vibrates so terribly it burns out bulbs, and only bulbs in the headlight.

Ive always used the same halogen bulbs I use in the dump truck,a bike doesn't take more abuse than a dump truck bouncing down the highway.

Some work got done today.
(mostly sorting out some wiring to the rear indicators)
I have torqued the bolts, they where all tight but about 50% of them needed to be tighned slightly.
And gotten so far that I can describe the vibrations a bit more and have felt the entire bike for vibrations.

It can be just me getting paranoid as well but it does vibrate a bit.
(I don't know how much they are supposed to vibrate)
My keychain bounces a bit when standing still and it is noticeable in the rear view mirror as well.
and my sloppy as fuck shifter does jump a bit when revving.

I have a poor and badly planed video on my bike where I try to show the vibrations (recording my keychain rattling shifter jumping and a screwdriver clattering on the headlight)
But where should I upload it? (preferably somewhere else than youtube since I only want to share it on this forum)
