Hi there,

I need an opinion please.

I have just completed rebuilding a honda cb500, the previouse owner had a faring fitted but when I recieved the bike it was in peices and doesnt look right when its fitted.
I have attached a two groups of pics showing differnt mounting positions and would appericate advice on which is the best position.

Position 1 suits the some of the brackets (roughly made) that were supplied
Position 2 would need the faring and part of the screen cut to allow full lock on the handle bars. I feel this is the best position.

Thanks for the help.

Brad
position 1




position 2

Brad, The main thing to look for is that the cutout where the clipons come out is high enough that your hand doesn't have the edge of the fibreglass rubbing it. You should have less lock on your racer than you had when it was a road bike, and you might need to change the stops on your frame. Have a look at the lock on a TZ sometime. If you get the fairing mounted right at the handlebars by adjusting the front mount, you should then be able to get the rest right.
I usually try to set up the front mount so that it is a piece of tube which just plugs in. I use a bit of aluminium round to screw to the fairing with about 30mm to plug into the tube welded to the front of the head stock. I usually drill a 4mm hole at right angles through the round and the tube and use an R clip to hold the fairing on.
When you sit on the bike and take a racing crouch, your head must clear the screen by at least a couple of decimetres.
The rear mount is just two bits of mild steel strip parallel with a cross tube welded on which bolts to the rear engine plates. I use two more bits of Ally round to plug in, and a couple of R clips to hold it on. When you drill the holes for the screws for the rear mounts you need to make sure the fairing is level, and clears the engine near the bottom inside the fairing.
If you sit on the seat with your feet on the re****ts the front of your leg should clear the rear edge of the fairing without putting any pressure on it.
If you use the R clips you can get the fairing off in about 2 seconds to work on the bike. You just sipmly pull the clips and unplug the ally round bits which are screwed to the fairing.
If you set up the front of the fairing, and find you can't get it level, you've got a problem. Might be the wrong fairing for the bike. The engine shouldn't collide with the inside of the fairing, when the fairing is level.
To work out if it's level, have a look underneath. Sometimes it's a compromise with the top edge.

The word 're****ts* in my post unfortunately coincides with good old Aussie slang for your posterior where the asterisks are. Sorry I can't give you a clear message but the programme running this forun give a bit of stupid censorship. It won't accept **** !

When the post first appeared I couldn't access the photos.
Even with the photos I can't see the differences he's talking about.
I thought this forum was about historic racing, even so I wonder at the height of the bars, doesn't look 'standard to me'.

In the second photo the faring looks miles too high. The problem seems to be in the hamdlebar height. Looks like the fairing is intended to be used with fairly straight bars.
In the last photo the fairing is at about the right height but the rise on the bars is too much. Looks like you need lower bars, and shorter cables.

Hi there,

Thanks for the replys, I agree with you about the position of the faring (lower) being better in the second photo.
I had a look at the handle bars and will rotate them back about 1" as they look a bit too far forward.
Apart from the faring and a gear sack rack, I am trying to keep the bike as original as possible.

Cheers Brad

I wonder if the fairing is intended for a standard CB500? The handle bars should poke out of the cutaways, in about the middle. You might get the bars a bit lower by pulling them back, but from the look of the photos, I think you'll be buying another pair with a lower rise.
