Optimizing the intake of Zane 750?s

[Thomas aus LAU]

There is a possibility to optimize the hoses to the air filter box. This applies to the Zane bikes, in which the suction hose is led through the front frame (normally 750?s).

The advantage:
- The fairing can be removed much more easily
- Much more air passage through thicker and inside smoother air hoses

You need
- a heating hose from a Hummer/Humvee
- two empty silicone or grease cartridges
- four hose clamps
- knife
- sandpaper

manual
- remove the tank dummy
- remove the old air hoses
- measures the length of the air duct through the frame and add 2 x 2 cm
- cut the empty cartridge to this length
- deburred on the inside at the cutting edge
- guide the cut cartridge through the frame until it is in the middle, the cut side points to the rear
- cuts two matching pieces from the heating hose from the frame to the airbox and fastens them with the hose clamps
- cut two suitable pieces of the heating hose from the frame forward to the inlet connector of the fairing and fasten them with the hose clamps

Finished

If you have to remove the cover, all you have to do is open the two hose clamps in front of the frame.

Thomas I see you have a steering damper - is the bike lively ? Does it need it ?

Clever idea Thomas. Anything that makes a Zane more user friendly has to be a bonus. The ones I've worked on always astound me with the sense that so many bits have been tacked on as an afterthought. Last time I felt like that was working on a Triumph Trident!

Team Enzo has great experience with Zane bikes. The fork, rear suspension and the exhaust are usually optimized.
Likewise, all plastic parts are replaced with carbon fiber parts and a steering damper is installed.

"Pilot" from the LCO drives this Cup Laverda from time to time on the racetrack. He says that the handling with the steering damper is significantly better.

Thanks for the post, Thomas.  A good idea.  (Of course, it does occur to me that all that Laverda had to do to avoid this problem in the first place was make the holes in the frame that the tubes pass thru that little bit bigger ...)

On a similar subject:
In order to make it easier to re-fit the front fairing (and following the advice of an owner on the old Zan? Yahoo Forum), I got some rigid plastic tube - like yours - of the right diameter that it fits into the mouths of the air intake tubing.

I then cut two pieces, maybe 100mm long.  Now instead of having to fight to get the flexible air tubing over the spigots on the fairing (and then stay there ...), you simply slide the pieces of rigid tube down the spigots, from the front, and so into the air intake tubing.

I'm sure people will say that this reduces the air intake and that all kinds of disaster will surely follow.  But I haven't noticed any difference ...

Not sure if I've explained myself well above  :-*.  I'll see if I can take a photo ... (the bike's currently buried under covers in the garage while I busy myself with re-juvenating the suspension on my old Ducrappi ...).

I used a smooth bore food grade hose with a stainless wire instead of the thread as on the hummer tubing. If you compress it lengthways it just pushes out again like a spring. I used 50mm communications conduit ( I think) for where it passes through the frame, but only had 25mm poking out from the end of the hose. Did that both sides of the frame. No clamps to undo. Just pull the hose back against the spring tension and pop the spigot out of the frame.

Now, that sounds a good solution!  Didn't know such a thing even existed.  Thanks!

Must admit I am considering fitting a damper to my race bike as had quite a moment on the bike in the one and only race I have completed so far. May consider it for the road bikes as well, although it hasn?t been a big issue so far. one was definitely a bit flighty but I initially put that down to worn tyres and perhaps slightly loose steering head bearings.
