Building my Jota

So the battery arrived, its so damn light. I have given it to people to hold, and they all expect it to be 12 kg or there about, so when i place it in their hands, their hands bounce up under an unexpected light weight... hope I explained myself well, there. The battery is a shade under 175 mm wide, 85 mm deep and 130 tall. You can just make out on the scales its 1722 grams , which is 1.72.2 kg .Insane!

Im putting one of Antigravity's battery trackers on it too...it requires an app, but lets you know the battery health when you come within 10 meters of the bike. these batteries are a big investment, so its good to know if something is up with it, as the battery tells you via message. Along with a whole pile of other tech data.

I mocked up quickly on google sketch up the idea for the combined battery tray and electrical bulk head. I didn't worry too much about keeping it in scale, the bulk head will be around 3-4 mm thick, and the box that slips into the tray will be 2mm thick carbon. We have already made a proto type box, its pretty rough, and will have more care taken over the final one. this box  will slide in to the cut out in the electrical bulkhead  cut out, this was made for an AGM battery which would have stood about 75 mm above the original battery tray rails, but now I have the Anti gravity battery, i can lay that on its side, and I may well be able to keep it below that level , to hide it completely, Im checking this out when I get home tonight . There will be a lip all the way around the battery tray, for it to sit on the corresponding part of the electrical  bulkhead. The reason Im doing this is so  I can use the original tabs on the frame to hold the bulk head unit in place, which means the battery tray part of the bulk head won't need fastenings through it on the old battery tray rails. The regulator will be facing forward of the bulkhead in the fresh air, with the wiring coming through to sit by the M unit on the back face of the bulk head, which then leaves space for all the other wiring loom connections,  fuses,  to the M unit and battery.To cover all the electrics  there  will be a shield kind of like a box lid, that will extend out from the electrical bulkhead  which will be fastened down with tamper proof fasteners. That will pretty much hide everything from sight and give no public access to any wires, It will also cover the battery terminals.

This is so much fun to be doing this sort of thing, Im not a gadget fan boy, but the tech available for me to be able to do the things that  I am with this bike, is pretty cool. And its so intuitive and basic that I can do it myself which is a huge bonus, of not having to pay someone else to do it. So within my skill level, I get to own a few of the jobs on this bike as being done by myself.

That's very cool and very neat! I'll be starting on my own battery and electrical box for the SFQ very soon, so interested to see what you're doing. I've also got to decide between a Li-Fe-Po and a gel mesh battery - obvious weight savings but I need to know the extra dough is worth it and that it'll crank out heaps of amps for a hi-comp 880 twin ands last for long periods with possibly little use (worst case scenario!!).

Great project you're doing - it is indeed satisfying to do stuff yourself. I just did my first test of the sheet metal rollers I bought to make my exhaust sys and other bits - excellent result on .7mm stainless, That was for short 70mm tubes to connect air filter pods to my custom intake rubbers.

keep the pics and the story coming!!

Hi ,
I dare say you thought of it.
Make sure all your electrical components including battery are rubber mounted.

Hi Andy

thanks for the thought , i will be rubber mounting the electrics.

cheers

Don't get it... what's the use of finding out the battery's flat when you're 10 metres away, and probably miles away from the charger?  Gonna find out soon enough, I mean, it's only 10 metres.  :D

Will the app be able to recharge it? :D

:D :D :D :D :D
It has a re start function which gets one last start out of the battery .. but if I get the message the battery is flat, then I know I can stay in the  pub ! And not waste my time trying to start the bike.  Perhaps Chris K will agree that?s worth it every time  :D
 
There?s always a good reason....  :P but a flat battery is not one of them.

Pulling everything off a bike to get to the dead battery in an English petrol station car park in the middle of BFN is not my idea of fun. Hey TTW.

But if you want your Jota to work like KIT the talking car, that?s up to you.

Luckily in Spain they sell roadies in gas stations , some even have pretty good cafes too

Hadn?t thought of the Kit light ... but if that gets me the hot chick that worked with michael knight , then I want 10.  :LOL:
 
I got a sneak preview from the painters today, they moved quicker than I thought they would.
Already the orange has been sprayed, 3 layers, now they are prepping everything for the clear coats that are going over the top.
If you look at the tank, you can see the masking over the fuel level window . Im really looking forward to seeing the tank finished.
Next up stickering, if that looks any good , everything will go back for clear coating over. I may live with the stickers on the bike in the shed and around the house for a few weeks, just so I get used to seeing it and see if I like it or not, before it becomes permanent.
The seat is coming along too, I had quilting done on one section.  I had a change in person to the wonderful Carolina, my normal guy, said he wouldn't get as good a finish as he wanted in the leather I chose., it  is quite thick black suede. Once all the components are stitched together, I will soak the leather in water, the sides are all left over length, then we punch holes in it lace it on the seat and tighten up all the lacing, so it takes on the seat profile, and then once it has been stretched into shape, dried, it can be fitted/ glued on the seat pan.This method works with things that we leather her in the shop for classic yachts blocks , tiller arms, and gaff rigged boom crutches... lets see how that goes for us on a laverda seat ! After that it gets scotch guarded to protect it from the sun and the elements.

So I picked up all the painted gear yesterday... it was a really good thing at the end of a long day. It came out really good, and I managed to sneak an hour in the shed putting things back in place on the frame, before we had to head off out for dinner.
Getting them home I felt i was transporting the crown jewels, so they were all spaced out around the car... the seat unit was strapped in one of my kids chairs in the car.
Tonight its on to the battery box setup, should be finished soon, now the rear guard is back in place , I can make sure it fits in nicely around there.

Todd, the paint looks super ..... stop the build now ...... I hate it. :P

hahahaha I was going for Ho Hum..... as Cosi puts it  :D, but I think I over achieved to 'ken awesome
 
looks great, but ditch the keyed caps, unless you live in a really really bad neighbourhood  ::) :-*
Too many obstacles in life already :)

I would prefer key less caps, but its best not to leave a bike in the street without them.... learnt that with my norton

Don't crooks know how to pull the hose off the taps then?


good point... it wasn't so much for stealing, there was a bunch of sugar that had been poured in the tank. We were inside a cafe and the bike was parked on the footpath outside, so  we didn't have a full view of the bike, then when a crowd cleared from outside I saw someone emptying a sugar jar in the tank... they must have thought it fun
