2011 Baotian Project "Street-Wolf 4-2-1" - Scootrific

[Scootrific]

Today, before coming to my day-job place, I vent to garage and did some fast work, by welding a Starter solenoid place to the under-seat area. Also, made wires for it.

1. The red beafy wire with 40A fuse from battery + side to the solenoid
2. From solenoid to starter.
3. Second beafy red wire from starter solenoid to the M-Unit Blue + terminal.

I continue the wiring work next time, I hope. One dude will come and look at my Baotian BT49QT-9D, what is sor sale right now. I hope he will buy that, so I can put the mone to this project.


Some solenoid wiring pics:

I was thinking about wiring little bit and connecting lights, buttons etc. I´m planing to use Deutsch dt 2-pin, 4-pin and 6-pin connectors. I believe, that going this way is safer, then using the original connectors.

Indicators = 4x 2-pin
Rear light/ brake light = 1x 4-pin
Front Low/High beam = 1x 4-pin
Front position light = 1x 2-pin
Starter solenoid (start-button) = 1x 2-pin
Regulator/Rectifier = 1x 4-pin
MAgneto/Stator = 1x 4-pin
Lock/kill (with key) = 1x 4-pin
Oilpump = 1x 2-pin
Temp sensor (oil) = 1x 2-pin
Temp sensor (head) = 1x 2-pin
Munit inputs and outputs = 4x 6-pin

Total 16 Deutsch dt connectors (5x 4-pin, 9x 2-pin and 4x 6-pin). (Might add more)

I think, I will add a number to my project name too. "Street-Wolf 4-2-1"

"4-2-1" means: 4-Stroke, 2-wheels, 1 cylinder

Yesterday, I sold my Cube Attention 29er mountain bike, what was sitting around and collecting dust. Reason for selling the MTB was, so I do not use the MTB anymore and second of all, I needed money to invest to the project electrical upgrad or so. So I went and brought some connectors. I only brought five Deutsch dt 6-pin connectors, because the dt 2-pin and 4-pin ones were not available. But I found solution for that, while I was standing on a electrical aisle. I found little bit cheaper watertight wire connectors 5-pin, 3-pin and 2-pin. Also, took some indicator lights too and new tool to compress the metal wire ends, hat go inside the watertight housing. Brought some ring and flat female terminals + license plate Led light too.

Today I brought 2 rolls of wire (black and Red) and some wire connecting rods (picture 1). Made 2 DIY distribution blocks for Power and ground wires for the scoot. I did not have my soldering station at work, wo I will fine tune this distribution block thing in the garage, by soldering all the ends and connecting all the wires with solder. Also I will heatshrink the blocks after soldering. But for now the distribution blocks look like this (picture 2).

I took few days break from garage, because the trail to the garage, from my work place was so wet and icey and also down hill. I decided to not work on my project, but yesterday I went and did some soldering and labeled all the M-Unit wires.

Yesterday, I went to garage and made a cart for my Lincoln Electronics welding machine:

This project has been on standstill so long. I have to buy and 50cc 2T engine, put the scoot back together and then I have to drive it to DMV or something, to get it back legal, with documents.

[Scootrific]

I was thinking, and maybe it is cheaper to convert the 90cc 4T engine back to 50cc (temporary), to get it legal. Then I do not have to buy an new engine. And after passing the legal stuff and getting the documents, then converting it back to 4T 90cc.

[Scootrific]

This project has been on hard brakes. But, I decided to ditch the 90cc engine, what is on the bike right now. Im gonna replace it with Piaggio engine, what was on 2007 Aprilia Street. I got the wiring, engine and other stuff for 200€ from other side of the country. I think I will deal with that project, when next vacation comes. Its a 50cc engine. I need that, to get my document right again on DMV. Because the scoot was too long off registration, that now I have to show it to DMV, to get it legal again.

For the speedo, I will use Trail tech Vapor maybe

Today came a package from other side of my country. Inside was Piaggio engine, with wiring and cooling system and engine mount. Now I need to fit it all to the Baotian frame and make radiator mounts. Also need to test fit the Baotian wheels too. The engine and all other parts are from 2007 Aprilia Street.

[Scootrific]

Today, I ordered a radiator mounting bracket for 2000 Aprilia Street, I hope that fits the 2007 Aprilia Street radiator too

[Scootrific]

Today, I worked little bit on the Baotian, while I was waiting for one dude, who came with the garage door material. I took off the 90cc engine and painted the frame little bit. Also, I unboxed the new 2T fuel tank, with sending unit and the cap.

In my mind, all is easy, but Now I need to think, where the bloody hell I put the radiator and does the Piaggio engine fit to the frame.

Today came in a package from Germany (Trailtech) for my project.
