Re-baking my ST1300 (Almost full redoing)

[leondante]

Well, I'm now looking for adapting AN3 hoses and accessories to the ST1300 metric standard. Banjo fittings are no issue as the banjo standard fits correctly, but AN has the thing that it's 37º instead of the 45º the ST1300 has on the mating surface, creating big problems when bearing the 200 bar the thing could reach when working in harsh conditions. I really don't understand why not rounding up those sizes so you don't end missmatching damn stuff for free. For motorcycles's sake...

Well, I wanted to check the angle of those fittings in our ST1300, so I took a silicone plug I put in the PCV when cleaning it, cut it in half and put that thing in my scanner at maximum resolution. Then with GIMP I just checked the angle, being it of 90º, meaning a 45º from the longitudinal axis. AN3 has those stupid 37 drunk weirdo degrees, so I need adapters.

The scanned piece of hot glue showing clearly the angle, or good enough so you can be sure if it's 37 or 45º:




Fortunately AliExpress has those adapters for getting even a ravioli well fitted with the AN3 standard for 3€ in stainless steel, so the future seems not that bad. I just need 3 by the moment. Maybe tomorrow or so I'm doing a fancy shop list for the parts for creating the hoses. And maybe with just 50€ I'll be getting new and with good standards those 3 or 4 hoses I have more cracked than Windows.

One example of the many adapters in AliExpress: https://es.aliexpress.com/item/1005005369189214.html

I've seen in some of these AE products that the working pressure is 270 bar and the bursting pressure 400 bar. I don't trust them at all, ever. But, hey, I know my emergency brakings for my dear life could reach around 60 or 80 bar. It's good enough. I have plenty of margin for failures. And be sure I'll be happily jumping over that rear brake pedal when testing it, just to be sure it cannot burst or dissasemble when braking. I have big respect for brakes, suspension, tyres, bearings, steering, wheel balance, among few other basic passive security things.

I like where this brake issue, which worried me a bit, is going. Learning to create brake or hydraulic hoses and knowing where to get the parts is amazing.

I'm editing this post to add that I've just found this in AliExpress this part to adapt EXACTLY what we have in our motorcycles. I'm impressed:

Some pictures of one of the three hoses I'm not leaving as they are even they are working "properly". Here you can see the steel block that I've found in AliExpress in inox steel (do you call it in your place?). The original is 29 mm long, the one in AliExpress is 32 mm, that's the only difference, all the other sizes are the same. Sad it doesn't say the seat angle so I can be fully sure is good enough.

Just opened the ABS rear pump motor, and as I expected, it was dry as Tutankamon. It needs a bit of grease. I'm taking pictures later. I just started cleaning the rear brake master cylinder. Thing had beans inside, or so...

 

[leondante]

Anyone can tell me where the rubber flap covers should go? I expected to have information in the workshop manual about it but there's no even a crumb about its existence. EG: The long one with the four holes, should be over the alternator or over the admision stuff? I have two or three more and I have no idea at this point where did I take them off from.

 

[leondante]

These days there wasn't anything worthy of pictures. The rear master cylinder was a bit dirty inside, nothing special, despite outside was horrible. The SMC started to work close to properly after some days mounted again with brake fluid inside. I taped the openings so it prevents the brake fluid to take humidity and make again some nasty thing it does that I don't like at all. It takes humidity and creates water bubbles that for some reason "eat" the aluminium.

After some research, I found the tool to create brake hoses myself for around 150 euros, so I think I'm buying it. Getting the four broken hoses I have is 120 euros, so I would rather get the tool and make my own hoses for less than 200, and I'm getting the tool virtually forever. It's not and will be not my last motorcycle or reparation, fully sure.

You can see in the picture the very first component that get the heat treatment in the wires, the rear ABS sensor. A lot of wires are broken because the heat, and I gonna fix them all, I must. Luckily I'm exhausted in life of fixing wirings, so is no issue for me. I have plenty of stuff and tools for fixing this kind of damages. It will take long, but is perfectly doable and will be better than new, as I'm using heat resistant wirings and things.

Greetings, the mechanics don't scare me, but the electrical part... except for very simple things, the rest is a no-no.
Vssssssssssssssssssss...

As the mechanics, it's about the diagram. We have the workshop manual with all the step-by-step things for putting all together properly. The same we have in that manual about every wire in there, and all the tests we should do in order to get the thing fixed. I have no damn clue about what is each pin in each connector, but I have that information in the wiring diagrams, usually. From there is more about each wire getting proper conduction to the next connector. And from there is about getting well diagnosed which part is failing if it's broken. The most important things are a cheap multimeter, good scissors, tin and soldering iron, from there few more things.

I encourage you to follow this thread as I'm fixing the wiring soon, probably this december, and I am sure I have the most common problems of the ST1300 here, as this bike was very used in city and all the wirings are really bad. The tools I'm using are a 15€ soldering iron, a 25€ crimping tool, some heat resisting wires, common wires, heat resisting sleeves and thermic retractile (again I have no clue about the name in english), cheap-as-salt scissors and a 3€ kit of electronic tools for dissasembling the connectors. From there is about workworkwork just substituting wirings. Also maybe I'm putting new connectors somewhere, if I found them are very bad. Connectors are cheap too, they sell boxes of different kits mixed for 10€ or so.

I'm installing a GPS tracker, a radar warning device and a 2-way alarm that I'm sure everybody will like.

See you soon tangled in wires.

Well, today took the bad hoses to a hydraulic workshop with good reviews and they got me a "more than 400 euros" price. I have around 5 damaged hoses that for sure they work, yet... But have the nailon threads exposed, asking for bursting out everything. So I'm buying for sure the hydraulic press for creating them myself, as doing it that way will be half the price.

I was under the impression that the equipment/supplies to make your own brake lines was unobtainable. Thats a big savings. Can you post the link to the brake line equipment youre looking at. Thx.

 

[CFL1300]

Greetings, of course I will continue to pay close attention to everything you are doing, especially the electrical section, to see if I can learn a little more. You are doing a fantastic job.

I thought the same, I understand you. But chinese dudes are getting ahead over every damn industrial thing, making reachable unthinkable tools for personal use.


This press was at 500€ at the workshop/store I went to.

(EDIT: This press CAN NOT do the hoses in our bikes, the smallest it can do aren't small enough. I'm glad I noticed it BEFORE buying it. But this is beter, as the one needed cost half than this one).

It can do a lot of hoses, the ones at our bikes are the smallest ones it can do. (EDIT: NOPE, it can't). This press IS EXACTLY THE SAME, NOT A """GOOOD""" ONE, but with a different sticker at the store I visited:

(EDIT: The correct press, as I think by now, that can do our hoses: https://es.aliexpress.com/item/1764469187.html


This part was not available at the workshop, they said they would take out the old terminals and refurbish them and crimp them again. I'm thinking about doing that, as I can solder them new sleeves because I have a TIG soldering machine, so I can do small jobs like that one and reuse my actual stuff. Also I actually would rather use those because the nice curves they had, which the generic terminals doesn't:

I will have this seriously in mind so I can do it better to give you the best I can about electrical stuff.

The sleeves than you can solder to the old couples so you can refurbish the old ones and reuse them:

Hello everydude. I'm now fixing some stuff in an extremely horrendous van I have for transporting my stuff, before the hard whip of winter come around here making it a tortuous experience to be outside fixing it without losing some fingernails.

Next thing in my bike is to finish cleaning the brake lines and front ABS modulator and install them, then the wiring is the next challenge.

I'm trying to finish the things in the van so I can have everything ready before the new parts for the bike arrives in order to lose the less amount of time possible. By the moment I'm stuck until I get my next salary and buy the new parts, except for the things I mention before, which I think is not of interest except for the wiring.

After the wiring, the next things are cleaning and reinstalling the admission and creating the new hoses for the brakes.

About that, I'm editing the previous message about the terminals crimper, as it's not the proper one.

The correct one is smaller and cheaper, and after measuring our brake hoses properly I noticed they are a lot smaller than I expected. Also looking in detail the terminals, YES, that crimper would work really well for it, or that's what I think by now.

So I'm glad that the future seems brighter than before, even being not-that-bad in the past.

This is the crimper tool I'm pretending to buy now:

By now I need a lot of parts that I hate to have to wait for so long to get. I have not finished the front wheel yet, the front fork, the valves covers and the PAIR valve and blablalbalbla, lots of stuff that are supposed to be done by now. Beh, life is like this, anyways I was ready to be doing this thing until March or April. I just hope not to need going longer than that...

Greetings, little by little you will get it, keep up the good work

Our 1991 1100 was the last bike I restored....ending over 50 years. No matter how well I planned and collected parts prior to tearing one down, I always missed something and ended up waiting on more parts. On the plus side I always had a bike to ride.....it's all been cheaper than therapy.
