stalled project getting moving again

[Simonr501]

looks to me like the entire fairing is sitting tipped downwards at the nose, resulting in the long arms from the fairing shell sitting tilted "Up" and a bit too high. They do not line up with the brackets that mount to the bike's frame at the coil bracket. The bike itself is pretty much exactly level in the photo.

this fairing and these brackets came off a crashedJota, the fairing was pretty badly broken and the various brackets were all bent. I have done some pretty significant straightening and aligning of brackets with a torch and a small sledge hammer.

I think I need to raise the nose of the fairing which will drop the tails of the faring shell along the sides of the tank.

Are the tails of the fairing supposed to be level with the bottom of the fuel tank?

How do the tails of the fairing shell mount to the brackets. Is the bracket arm supposed to be above or below the fairing shell?

IS there supposed to be any rubber mounting of the tails of the fairing shell?

If it is the same as the Jota 120 Paul then yours is tilting forward at a most crazy angle, here is the original factory poster:

The brackets from the coil mounts just clear the underside of the tank and top of cam cover and on mine at least go BELOW the tails of the fairing. If I tried to go ABOVE then it would all be crooked.

I would rubber mount the tails to bracket, I believe I have done this on mine, but it looks like I tightened too much as one side of the fairing is now cracked adjacent to the bolt.

It certainly does look like your bracket that goes to the rubber mounting is still bent.
I did a modification on mine  The 'boomerang' shaped part that bolts to it fell off when I unbolted the fairing, just missing my shiny mudguard!!!!! So I drilled a couple of holes with a big chamfer and put countersunk screws through so it all stays together when the fairing is removed.

Also take note that the centre line of the indicator lenses is roughly in line with the bottom of the tank. So overall even if level, yours looks too high.

Bye the way, how many tape measures do you bloody need?

Paul,

I suspect that the bracket that bolts to the steering stem is either fitted upside down, or has been over straightened, if indeed it needed straightening at all, as it is meant to have a kink in it.

Attached are some pics of Mirages fitted with an S2 fairing, as well as a view of the fairing brackets (courtesy of Grant).

looking at Grant's photo's posted by Tom (thanks to both!), the bracket that I have that bolts to the steering neck is really bent. That bracket is thick steel, it must have taken quite a hit to bend it. After a lot of initial bending back when I was repairing the fairing I have the main bracket that mounts to the fairing and the headlight bucket looking pretty much like what I see in the photo (although it could maybe need some more work), and the side brackets look about the same. The only bracket I have not altered yet is the bracket that bolts to the steering neck.

I'll try to emulate the bracket shape for the steering mount neck that I see in the photo, then try another fitting and post some more photos.

Final alternative may be to buy a new set of mounting brackets from Wolfgang whenever he gets back.

Paul LeClair

ps - Simon, you can never have too many tools, although the tape measures are actually a sad reflection of my aging and slowly declining vision, I have had to add large type tape measure versions to the collection of older tape measures I can't read anymore. Same reason I have had to go to digital calipers with big readouts as I can't read the my mechanical ones any more, sucks to age but better than the alternative....... 

 

[Paul LeClair]

modified the steering neck bracket with a torch, vise, and small sledgehammer, to more closely match the shape shown in Grant's photo posted by Tom.

still not perfect, but much better, will now fit the fairing side brackets on the frame near the coils, one of those brackets is bent more than the other, probably also from the crash the donor Jota  endured and then  tweak all the mounts as necessary to get a better fit.

[Grant]

That looks much better.

I think I am now on the right track concerning the fairing mounting, so next stupid question, as I am getting ready to fit the rebuilt carbs......

the crashed bike came to me completely stock, including the airbox with all the internal stuff that I assume is likely mostly to reduce intake noise?

The original  airbox is broken, and I have a brand new reproduction air box from Wolfgang. Normally I just fit a bare shell of an airbiox, filter, and back panel, which leaves the filter fully exposed full length across the bottom, rather than restricted to a single snorkel.

I am using the stock Silentium pipes, which I have never used before. Is there any purpose or merit (other than reduced intake noise) to fitting all the stock guts to the airbox shell?

Maybe 20 years ago I found it hysterical when one of the older carpenters I was working with,he was in his late 50s and I was in my 30s,was complaining about not being able to unscrew a Philips headed screw,not surprising as he was pocking the screwdriver  into a pop rivet.I now dont find it so funny. Especially when I cannot find my glasses and there on top of my head.

 

[Paul LeClair]

Hi Vince

so sadly true.. I actually now have bi-focal safety glasses, sometimes used in conjunction with a magnifying glass for very tiny things and details...... : I also have had to resort to inserting a magnifying lens into my welding helmet, that was a sad day  :'(

Paul, I routinely gut the internals of these restricted airboxes.
Re-jet accordingly and run it with the stock exhausts.
A common mod was to drill 4 equally spaced holes around the periphery of the end of these silencers.
Still muted vs Jota silencers.

thanks, Grant. Gutted airbox it is. Should be going on this evening after I finish work for the day.

as for the Silentium silencer's, I have a spare set of Jota mufflers as well, I am going to try the Silentium's first as is, would probably fit the Jota mufflers before drilling holes in the Silentium's. For my RGS I did drill four holes in the rear of the stock RGS mufflers I had re chromed, can't say it seemed to make much of a difference, then just went to the stainless steel exhaust Wolfgang sells for the RGS.

Wolfgang's replica air box shell, which I painted with Krylon Fusion for Plastic, in satin black. Had to drill the replica shell for the bolts for the lower mounting tabs, no big deal.

Totally rebuilt carbs installed, now hooked up to brand new throttle cable, the choke cable hooked up at the left handlebar.

Very satisfying to twist the throttle for the first time in two years and hear/feel the new slides going up and down...

Paul LeClair

 

[chrisk]

That looks much better.

If you like those butt ugly fairings, frankly I wouldn't have wasted so much time on it.

Glad you got it sorted though.

I think we all know what you mean - something very tangible about 20th century mechanics that ecu's/electronics will never replicate...

" I logged onto the laptop and dialled in a smooth ride-by-wire curve"  doesn't seem to cut it somehow 

Men need to make fires.  They also need to hew parts from solid metal and invoke ridiculously loud noises from old motorcycles.

I am finishing the electrics this weekend, hopefully. Have come across my very first "Dreaded Previous Owner" bodge of the entire bike. Weird poor wiring "repair" to one of the turn signal indicators on the instrument panel.

I am going to replace all the bulbs in the indicator panel while I have it open. Does anyone know what size/model of LED bulbs would be a reasonable replacement? Failing that I will need to find the correct bulb size for the standard bulbs.

Paul LeClair

 

[Paul LeClair]

moving along, dash assembled and installed, temporarily using all new conventional bulbs while I wait on my LED order, today (Sunday) going to try tackling a remaining wiring puzzle for the headlight shell bundle and turn signals

borrowed Keith's method of lowering the instruments a bit by flipping the mounting over.

Whoa, Paul, you're making some younger members (I'm 46) feel a bit lazy with your breakneck pace. Take it easy, it's Sunday-you deserve a respite!

I actually got side tracked by my two grandkids, 2 and 3, today, went to have breakfast with them intending to get back to the bike project for the rest of the day, but was having so much fun I hung with the grandkids all day, it is now 6:30 pm and I haven't touched the bike today......., yet

on a different subject, I am wondering if bar end mirrors will work with  Series 2 Jota fairing? Anyone? I am thinking of ordering a pair of Halcyon bar end mirrors from the UK, the stainless steel rectangular 820's https://classicpartsltd.com/

Hi Paul, the Fairing can limit the full handlebar rotation depending on how bars are set up, usually brake / clutch lever will fowl first. Bar end mirrors will not cause any other interference as they are well away from sides of fairing. ( I have an old rectangular one on mine, just like that 820 - provides good vision)

 

[Paul LeClair]

thanks, and thanks for the photo. The project bike is still clamped on the work lift table by the front wheel, so I can't presently turn the handlebars. I will go ahead and order the mirrors, as you pointed out the issue is likely going to be the bars or the master cylinders.....

Paul LeClair

ps have not seen a Vetter Triumph in a long time, what is that called? Hurricane or Tornado or something, I have forgotten. Neat bike, tiny fuel tank.
