for any owners who may have removed/installed their duel headlights,need your input.all the breakers on the bay feature headlights but zero mounting hardware at the 4 corners.http://www.partzilla.com/parts/search/Yamaha/Motorcycle/1987/FZR750RT/FAIRING-COWLING/parts.html Yamaha part diagram offers only the rubber grommets.are their metal collers that fir into these grommets? type with a flange on 1 end? screws or bolts to fit? the local Yamaha parts dealer also had no clue.why parts breakers don't include the hardware is a mystery.same diagram omission for a fzr1000.I ordered the 51L-84332-00-00 SPRING,SCREW but is nothing but a short coil spring(???)#12 in the headlight diagram.great site & hope someone can offer the solution........

The reason why the breakers sell the headlight assy. without mounting hardware is because it is not part of the headlight !

The headlights slot directly without any other part (except a large foam gasket that is figure 8 shaped for the headlight aperture) straight onto four plastic m8 studs with m6 metal threaded stud inserts that are part of the nosecone fairing.

Then the nosecone c/w headlights fixes to the "birdcage" frame that supports the nosecone and instruments.

There are rubber grommits in the birdcage mountings at each corner which the studs go through and then a flat washer and a m6 nut.

The nuts are a "special" and exactly the same part no. as the exhaust manifold fixing nuts.
Normal m6 nuts can be used as a replacement .

If you are without a nosecone fairing I realise the above information would not be immediately apparent.

The plastic studs are part of the nosecone and cannot be removed.
M8 bolts may be substituted or m6 with a fabricated m8 external dia. spacer.

thanks for taking the time to solve, should have known every manuf. does things different.couple other Q.'s/ the side fairing scoop ducts-where do the outlets attach or do they just point at the engine? and the nose fairing air tubes-where the right side attaches to the frame is the coolant hose-hardly any room for any air to enter.is this the correct attachment location? thanks.

Cannot help with airduct location specifically; I do not have that machine.
Below is a generalisation.

Usually on side scoops there are plastic deflectors that channel airflow towards the engine.
9 times out of 10 they are missing on a used/crashed bike and not replaced.

The nosecone ones are over 75% for show.
The small amount of air that is channelled via them, either just goes to the hollow frames and a small amount exits in the general vicinity of the airbox.

No air should go to the hollow frame, this should be prevented by a rubber grommet and all the air from the air tubes should exit in the general vicinity of the airbox.

Re: headlight to cage mount? + throttle cables.

Postby '87 750 RT » Thu Mar 10, 2016 8:09 pm

thanks for sorting the headlight issue.now can anyone advise how the air box installs? the 87's used a single throttle cable.since running a 1k engine Yamaha used a duel throttle cable setup.I have cable#2 in the rear slot of the mounting stop.but the airbox from a 1k engine will not seat completely on the carbs.seems to be limited by the #2 cable.anyone have a heads up to what I maybe doing wrong? thanks.Image

The shapes and attachment points of 1000 and 750 airboxes are different. Couldn't find a better comparison pic than ebay listings:

update-measured the joint ID as 48mm/ the 1000 joints are 50mm.just ordered the correct joints( less curvature ends in the box) & will see how it goes.
