New Zongshen RX3 (ZS250GY-3) Dual Sport

[SpudRider]

I just performed a quick search of the CSC Parts website. I couldn't find the temperature sensor, either. This part is located at the bottom of the left radiator, so it should also be listed with the radiator parts.

I've not seen them listed anywhere

On that picture seems to be three pieces:

- Thermostat (mechanical) body
- Temperature sensor (for the EFI)
- High Temperature switch (for EFI/radiator fans)

Regards.

it´s still a reliable and valued bike around here but years passed to it and its noticeable the lack of rear brake, poor lights, carburator with bad cool start, heavy structure, old style fork, not fuel indicator among other.
I recently owned 2 Yamahas XTZ 250 (the Tornado competitor) and consider it a step above it.

The XTZ250 is a really budget bike..
Old damping rod forks... They had the
choice of 3 motors WR250R / TTR250
But they went with the old low tec XT250
motor...

The XTZ looks the goods... under neath it's
a very budget motor bike ...It has no right to
carry the Tenere name...

I'm a Yamaha fan/owner... But Yamaha droped the ball
on this one...

Build cost was most lightly kept down for
it's intended markets...

I agree, people living in the third word (South America) are acostumed to suffer this, regionally produced low cost bikes, if you want to have a "real" Yamaha like the WR250 you should pay almost 3 times the local XTZ250.
Then you have another problem, the motorbike robery, my last 2 Yamahas XTZ 250 were stolen in the street with a gun pointing at my chest, one in December 2013 and another on February 2014, so I wont ride any Yamaha or Honda for a while ...

I agree. I think the temperature sensor which turns on the radiator fans is located at the bottom of the left radiator.

[katflap]

I had a bit of a play with it today


Sensor attached to the bottom of the left hand radiator.
---------------------------------------------------------
Disconnected it produces no error code

*Temp Readings in PCHUD still visible

Connector shorted with engine running turns on the cooling fans.

12volts at this connector so i think its likely to be a thermostatic switch.


Sensor on thermostat housing with the 1 cable attached
-------------------------------------------------
Disconnected produces no error code

*Temp Readings in PCHUD still visible

Loss of LCD temp bars on speedo


Sensor on thermostat housing with blue 2 pin conector
----------------------------------------------------
Disconnected produces error code (280 hex - 0118 temp (water) high voltage or open)

Temp readings visible in PCHUD but now are an exact mirror of the Air Intake Temp readings.

---------------------------------------------------------------------------------------------------
* Didnt check to see if the readings changed to mirror the Air intake temp readings on the first 2 sensors*
-------------------------------------------------------------------------------------------------------------
SO still not fully sorted

[katflap]

It would still be interesting to know whether the thermostat housing actually does house a thermostat or is just an alloy tube or boss to mount the sensors in.

At some point I will take it apart and have a look

That is exactly what I suspected. As always, thanks for doing the investigative work, Kat.

Inquiring minds want to know. Your unrelenting search for knowledge befits your position as Grand Poobah of The United Kingdom of Great Britain and Northern Ireland. This insatiable desire for knowledge also benefits, and honors, The Cult of The Zong.

I have my spare thermostat housing before me as I type. It is divided into two parts, and is held together with two 5 mm bolts which have 8 mm hexagonal heads. Each part of the housing has the word 'Skill' cast in the metal. Indeed, there is a spring-loaded thermostat located inside the housing. The thermostat could be replaced by separating the two parts of the housing.

The engine temperature sensor for Delphi EFI, with the blue, 2-pin connector, has the following writing inscribed upon it.

Skill
SK04052
131201

The dashboard, engine temperature sensor, with the black wire, has the following writing inscribed upon it.

Skill
130502

I suppect both 13**** numbers indicate the date of manufacture.

That's brilliant, thanks spud

Not that I'm expecting any problems with these components, but the more we know the better, should a problem arise

You're welcome. As usual, I agree.

Had a Chat With Gerry Edwards,

Man you guys are lucky, I see what CSC does for customer service and man do I miss it; my local dealer really doesn't care if I have an issue or not and since I do and have since day one, they asked me to take pictures of the front, back, left and right side of the bike. This for an issue with the carb that I have hand delivered pictures of and emailed (oh, they didn't get the emails (bull) I sent to myself at another email address, my wife, my son and a friend, they all got the same email and pictures). I feel it's just their long way to deny a warranty claim. They could have made me a happy customer right away and I told them this, or you can make me an unhappy customer; Motorstar (Eastworld) in Iloilo City, Panay has chosen to make me unhappy. I honestly feel that of a US customer had an issue with your Throttle-body unit that CSC would address it quickly and replace if necessary without the run around and crap I have to put up with.

Motorstar Philippines and Eastworld (parent company) are giving Zongshen a bad name and rep. Sure some of their carb's have the same problem and Zong should address it but it's not on all bikes, just random but if the dealer doesn't provide proper warranty service it reflects back to the manufacturer too.

I envy you US buyers.

I'm truly sorry to hear of your problems with MotoStar Phillipines.

Indeed, CSC is offering warranty coverage and customer service which is unparalleled in the world of Chinese motorcycles.

Agree: that sensor is merely a thermal on/off switch, connected directly to the cooling fans.

This sensor is dedicated and directly connected to the LCD dashboard, driving the temp bars indicator.

Seems to be this sensor belongs to the EFI control unit, providing the temperature feedback needed for the dynamic adjustment of the fuel/air ratio.

Not sure if it has been covered before, but here in Argentina we get the carburetted version, and the tank is NOT 16L, it only takes 14L (even though the specs says that)
