[Technical] Queries for TA200

[Pandoras Kitten 3]

For a 8 year old TA200 (same as mine), leaning the mixture out tends to improve throttle response but engine heats up fast at high rpms, decreasing power over a while.

 

Lean mix is good for light-duty short range work, for economy, keep it rich for long distance/ high temperature runs on the highway. Indeed a rich mixture increases vibrations but the engine runs at a much lower temperature. Which is good.

 

Mixture screw is located on the left side of the carburettor, towards the front of that seam in the middle. It's the only thing you can turn with a normal screwdriver so.. have fun with it and make small adjustments only (1/8 - 1/4 turn, and tune only when engine is warmed).

 

Sniff the exhaust to see whether you're lean, rich or very rich. Nothing like waking up to the aroma of unburnt hydrocarbons in the morning.

people,

thanks! will take the bike to planet and let ah-chong check it proper.

 

a trip to planet was done...

he resolved it quickly.

turns out there is a air suction relay valve which had failed in my ta 200 and he replaced it.

 

also added a chain tensioner.

I like these guys. they are knowledgeable and reasonable.will be taking my ta 200 to them for anything. cheers!

 

BTw, anyone care to explain the purpose of this air suction relay valve here? sequence of flow of air? and where this valve falls in the flow? thanks!

Ya Dr Chong is very reasonable and well verse in Phantom's sickness! That's why most of us will go back to him for our regular Blood Test, Injections, TLCs, etc... Hahahaha... yalah, he's good lah!

[wahwah90]

can i ask can we instead of diesel use petrol to clean our chain?

note, if your bike has red fur on it he won't dare to touch it

[pureice68]

Haha... I'll leave the red fur to you lah bro! Haha...

guys..this morning i accidentally ran my bike when d petcock is set at RESERVE.. so it ran out halfway, realised my mistake then changed to ON... so i topped up my petrol jux now in the ON position.. wat i want to know is the RESERVE part filled up as well? or its empty nw? dun wanna ride, empty, then turn to RESERVE, empty as well!

don't worry, its one single tank... you don't have to turn to reserve to "fill up the reserve tank"...

[naim]

thanks! hmm... but interesting... why when i was using RESERVE, it only uses the RESERVE amount.. not the full tank?

[VidaK]

lol of course not... when its at "reserve", it will use the entire tank...

[armani123sg]

from what i understand, this reserve function is like putting a vertical straw in e bottom of ur tank... so when u switch to on, e petrol goes in from e top of the straw... when run out of petrol, u switch to reserve, petrol travels through e bottom of e straw... can get e picture?

[naim]

but wen i was using it in the RES mode, it ran out... like empty tank.. dats wen i switch it to ON, then ok alr..

reserve tank works like this.

a rough sketch.

 

note th 2 different 'straw'..

Hello all,

 

rode into Malaysia recently in there evening and realised that our stock headlamp is rather dim, had to rely on a friends brighter headlight for proper illumination (he was riding a derbi adventure), any recommended bulbs we can buy and install ourselves to improve the brightness of the stock headlamp?

 

Thanks!!

[Pandoras Kitten 3]

At least your headlamp is dim. Mine is still pointed high into the sky, lol.

 

I let a car HID equipped S4 illuminate the road, an SP to illuminate horizontally while I supply top level illumination of the forest canopy from behind

[plush]

doesnt HID lamps require ballasts? if yes, then how do u manage to secure the ballast?

 

could it be that current supply to the bulb is not good?

what most of us did is to get a bulletheadlight... Then uses a H4 bulb..

 

* note : stock headlight cannot use HID or any other bulb. *

fixed up a S4 headlight and all is well....

Talking about this, I haven't got round to change my light bulb!

[Pandoras Kitten 3]

zpjohnny wanted a S4 headlight I believe.

 

If that doesn't cause havoc with the electrics (55W vs 35W stock) then I'll put S4 windscreen and label it Honda Super 2

Hahaha, better make sure you patent it!

Yalor got DIY VTEC some more leh

 

(Pickup @ low speed better than some super 4 - tested!)

air relay valve...United States Patent 3730226

 

An air relay valve including an enclosed housing separated into an air supply chamber and a control chamber by a flexible diaphragm Air pressure introduced into the control chamber flexes the diaphragm into the air supply chamber. This opens the air supply chamber to an air pressure source with ports directing the air pressure from the air supply chamber into air lines that activate, e.g., air brakes. The relay valve is further designed whereby the inlet from the air pressure source is kept open until the pressure on both sides of the diaphragm are equalized causing return of the diaphragm and automatic closing of the air pressure source. The present invention is characterized in providing a diaphragm wherein the two sides have equal surface areas exposed to the air pressure so that automatic shut off occurs at the point when the p.s.i. of the air in the air lines substantially equals the p.s.i. of the air in the control chamber with exhausting of the air pressure occurring through an exhaust port in direct communication with the air supply chamber. A further improvement is the inclusion of a dampening chamber to dampen vibration of the diaphragm assembly.

 

this ??

 

Wah chimz lah! Layman term can?

[pureice68]

just couldt figure out what is this thingy..maybe some one can supply answer..

instead i get question..haha

 

Hahaha... sorry lah! I'm more of a practical person so theory I blur blur lah! Maybe got to open up and have a look, hahaha... like wad Bikee always say "got screws means can open!", hahaha....
