Ready for the AGVoice Bluetooth communication system

S4 Sv is sister helmet with stealth sv, gjordes fram till ca 2012

Pris 2010: Considering the €299 requested for the decorative version (€269 in plain), this helmet still needs to be improved to be used peacefully on motorcycles dedicated to fast touring.

Both the Stealth and S-4 SV shells are a carbon-fibre/fibreglass mix.

Like the T-2 and the GP Tech racing lids, the ventilation system is an integrated version through the EPS liner, as developed by Valentino Rossi.

 They have replaced the S4-SV and Stealth-SV with the Skyline and Horizon models respectively (2012). Då togs ventilationshålen vid örat bort.

Skyline har Ventilation system with three front air vents.

Skyline does not have any rear exhaust vents or side vents, which the S4 SV and Stealth has.

Skyline has a “micro-lock” chin strap while the Horizon gets a double D-ring retainer.

Very comfortable, very light, very feature rich. Really good helmet for riding in hot weather or touring.



Regarding visors there seems to be conflicting compatibility tables...


Below is Skyline and Stealth-SV compatible with for example K3-SV.



-----------------  --------------

Two shell sizes and XS – XXL fitment sizes, with four different EPS (shock absorbing expanded polystyrene) liners. 

------------------  ------------

The AGV Skyline helmet is the direct replacement for the massively popular AGV S4 SV. The shell is Constructed from Fibreglass and Carbon, providing an impact resistant and lightweight shell. This Skyline range of helmets from AGV must be one of the most pleasing to the eye, with its aggressive stance courtesy of the deep chin-bar and top vents making it instantly stand out from the crowd. A major difference the AGV Skyline has over some of the other sports orientated competitors is the integrated drop down sun visor - meaning you'll never be caught out with the wrong visor again.


------------------  ---------------

AGV Sport Modular Carbon fibre helmets are made in China. By Boeing. They have a facility in China that makes cf parts for their aircraft and AGV couldn’t find a better solution that wouldn’t make the price too high.



--------------- This is the older AGV S4 - it's not the same   -------------

There are no air channels on top. And no indents for the ventilation outlets behind the ears. The shell is more round. The visor mechanism is also different.

Hyosung Sense 2001 and cylinder hunt

Cylinder and Exhaust part for 50cc Hyosung 

Some information regarding parts for Hyosung SD50. Avanti or Sense.

This one I bought in Surahammar, it has low cylinder compression. 60 PSI.

Therefore I'm looking for a new cylinder jug. Finding parts here in Sweden are hard.. Unless I go for a Morini but then my exhaust doesnt fit anymore. Plus might be hard getting a new flat flange Morini exhaust to fit..



Hyosung Sense 2001 cylinder with "old style" flange. Hard to find in my country.

Morini / TGB cylinder with flat flange, needs another type of exhause? Original wont fit.

Morini 50 AC 2T is called D1E41QMB



Old style from another view (SD50), the Prisma SF50 I think uses a flat flange:

Head for a Hyosung SD50 2006:

This is a fitting exhaust for the cylinder. Technigas Silent Pro is available for both types of cylinder flanges.

Tecnigas Silent Pro 0307182 – hyosung SF 50

------------- Flange-type for Hyosung Prisma 50cc etc , Morini / TGB cylinders ---------

Tecnigas Silent Pro 0307182 – hyosung SF 50

https://www.amazon.se/Tecnigas-Silent-Pro-0307182-hyosung/dp/B07F8JSHG7





-----------------  ------------

Maybe a Hyosung Prisma SF50 exhaust could be fitted to the Morini style flat flange. In that case you already have an alternative:


Hyosung Sf50 Tecnigas Next cost 1509 kr @ mopeddelar, but sold out for now.



Fits

- Hyosung Prima

- Hyosung Rally 50

- Hyosung SF 50 Super Fast

- Hyosung Super Cab> '08

 UDX frame from classic cycles in Germamy

Why can't we find any nice builds for sale in Sweden? Come on Producers. 

Nice Build by Derek Williams with Bafang BBSHD electric motor.

Fashion 10 inch wheel frame . From 2 stroke to a 4-stroke. The motor is a long case GY6 with a 10 inch rear wheel

 From 2 stroke to a 4 stroke.  Engine Mount are off a different bike

More info on the progress of Bobs build follows:

"The Geely . The dead 2 stoke has gone to the can factory and now I'm building a lowered GY6 50 / BBK drag strip bike , that will perhaps not be as fast as 2 stroke but it will last longer than 1 race !  Truth is , I'll never dray race it anyway , It's just to make me look taller !- Bob Bamforth

"The only modification needed was a short side stand and a different  swing engine mount of another bike . It all just bolted in nice and straight . To easy ! On these 2 stroke " Geely " bikes the oil tank sits in the seat bucket . I can either take it out and have more room or wash it out and use it as beer container ?" - Bob Bamforth

"It's a 10 inch wheel frame . The motor is a long case GY6 with a 10 inch rear wheel and the front is the stock 10 inch drum brake wheel . I can't fit a main stand and the side stand and lower engine mount are off a different bike . The whole lot fitted in with no modifications , Just bolt up and away . easy ! I'm not sure yet if the muffler will scrape on the road around corners ?" - Bob Bamforth


Lowered Fashion scooter with Long case and 10" wheel. Now GY6 4-stroke instead of 2-stroke.

Electric kick scooter with 4 persons

 4 persons on Xiami Pro or 365?

It makes you wonder, bad parenting? No parents onboard, parents home sleeping? Pretty dangerous trusting all that weight on that thing.

Bad judgement if you ask me. If they are parents I'm sorry for the kids.

Cleaning pilot jet or small channels in carburetor - Gör rent munstycke i förgasare, tips

 "Top tip for cleaning out jets and airways. Use a squirt or so of lemon juice in a vessel with boiling water, citric acid will eat and clean the crud without damaging the metals.

I’ve used this for years with great results." - Andrew Fairhurst, SYM FIDDLE Owners Club

----------------- Kalkosan eller Hessa kalkbort  --------------


//Även Hessa kalkbort bör kunna användas //

Syror angriper oxider väldigt effektivt. Tar även bort ytlig rost. Ett  tips är att doppa förgasaren i Kalkosan (avkalkningsmedel med fosforsyra och citronsyra, koncentration 1-5%) som man hittar i en vanlig affär. OBS! Det är inte helt riskfritt eftersom syror angriper metaller så som aluminium och zink – två vanliga material i förgasare. Lämna inte förgasaren i kalkosan mer än cirka 15 minuter. Gör om processen om det fortfarande är skit kvar. Vad jag har förstått ska man använda lösningen outspädd. Skölj noga efteråt med vatten och upprepa vid behov, du måste få bort syran. När allt syra är borta blås bort vatten med tryckluft så det blir torrt.

Hessa Kalkbort innehåller mindre än 15% koncentrerat fosforsyra.

Citronsyra (175 gr. C) har något högre kokningstemp än fosforsyra (158 gr C).

Så om du spär ut och kokar förgasaren i vatten med en smula syra kokar fosforsyran bort lite tidigare.

Kokning hjälper till att speeda på processen.

Going from 6pin CDI to 5pin CDI,

It sometimes can be hard to find 6pin CDI for Baotian 4-stroke Scooters. 5pin variants are common though so I made a conversion cable. 



Making a adapter cable from 6pin Baotian to 5 pin GY6 C.D.I.

Here's a video showing how to convert.

------------------ Good to know, according to Aidix (2010) -------------

If you block has an engine block code 139QMA or 139QMB.

"Not every scooter with such a block has the same CDI. That depends on the manufacturer, there are 4 or 5 different types of CDI's for Chinese scooters, which are not interchangeable and look the same. The Spnk/rick18 indicated is therefore the wrong one, and the text that says "fits all scooters with gy6 block" is of course wrong.
Just as wrong as saying that the same cdi fits on all european 2t scooters.

Rex is a sticker brand, the real brand is Qingqi. (Same factory as Peugeot)" - Aidix, https://scooterforum.net/threads/sport-cdi.191414/#post-3238140

About Sym - Sanyang

 Some history of Sym - Sanyang company

SYM has been producing two-wheelers for over 65 years now. They have a pretty good reputation, not like Honda but better rumour than most of the Chinese ones. However Honda / Yamaha parts are more expensive.

As far as I understand the Sym Fiddle 2 is produced in Xiamen Xiashing Motorcycle, China, so not manufactured in Taiwan.

With more than 1,000,000 vehicles produced, the Taiwanese group is now one of the major manufacturers in the two-wheeler industry. With the certification according to the strict criteria ISO 9001 and ISO 9002, SYM is committed to consistently high quality standards.

The development center ensures constant further development and renewal of the model range. As a buyer, you can choose from a variety of models between 50cm³ and 600cm³ cubic capacity, where the price-performance ratio is pretty good.

Sym was founded in 1947 as Ching Feng Hang, an import company of BSA motorcycles. It wasn’t until 1954 that the name Sanyang was first mentioned. Sanyang Electrics.

Sanyang Electrics was soon to be restructured into Sanyang Industrial Co. Ltd. Year 1961.

In 1962 Sym formed a joint venture with Honda begin local assembly of motorcycles. This made them the first motorcycle manufacturer in Taiwan.

The “monkey bike”, the Honda CB125/150 has been made by Sym since the early 1970’s. 

Year 1969, Sym started assembling Honda microcars such as the Honda TN360 and the Honda N600. These cars became very popular in their day. It was this 32 year long cooperation with Honda which helped Sym gain the knowledge and instilled Sym’s thirst for perfection and quality.


They say they have a high quality standard.

Older PGO BIG MAX 50 engine converted to GY6 150cc, rear original rim do not fit

GY6 150cc into 50cc Frame?

 Richard M. A. Corp converting his PGO Big Max scooter. Trying to get a short case GY6 150cc into the frame. PGO rims / wheels does not fit though:

"I have an old PGO Big Max 50 with a bad motor. I bought a Gy6 150, but the hub of the rear rim will not fit over the brakes that the new motor came with. I don’t know if the spline fits or not, I think it does. I need to buy a new wheel before I can mount the motor. 

The tire on the bike is 120/90-10, he believes it to be a 10 x 2.5" wheel."


Suggestion: Might wanna try get a GY6 short case rim because short case uses 49cc brake pads (source Internet, Jason H.).


Putting a 150cc GY6 into PGO BIG MAX 50cc frame.
Putting a 150cc GY6 into PGO BIG MAX 50cc frame.
Looks like 5 inch something?

Good to know: 50, 125, 150 all have different brake sizes
Engine seems to fit the frame at least.


Hope to see Richard succeed with his build. Good luck. Let us know how it works out!
