did tuning after installing the TDK and protec filter. i'd say it did make a difference to the torque! awesome man! one more thing just now i took out my pulsar stock plugs, decided to bring them home to scrub, and decided to be cheap and try to compare them to my old Zx6 denso IU27 plugs.. upon comparing, they looked similar.

but just wanted to play safe so i googled RG4HC and IU27....

and turns out that they are compatible!!! 'free' iradium plugs!! wootz!!

 

haha

but the tip is different

our stock is copper tip

with tdk and filter good torque

wait till you install the protec coils...

[-Gu0Zz-]

haha spaiduhz bro, nice to see that u have time to come chit chat in the forum. how's work at KFC today?

[-Gu0Zz-]

haha i'd like to give that one some consideration. how much does it cost btw?

[alvinyansg]

haha i'd like to give that one some consideration. how much does it cost btw?

 

the ones that the pulsarians bought this time round is $36sgd per coil

the price will flutuate cause of the exchange rate

and also there is shipping and the admin fee for paypal

so if more ppl buy then can share the shipping and admin fee

my bike hit 140kph! hahah.. was randomly trying.. got slight down slope..

[ORen]

Anyone using the Mobil FS1 oil sometimes feels that the oil is less efficient when closing to 1500km mileage ?

I mean, feels like changing it about 1000km before hitting the normal 2500km change ?

 

It's now twice that I am feeling the engine reving and overall gear shifting/accelerations are not as smooth as my first 1000km after oil change. Now I know it's normal to get a smoother bike after servicing and changing the oil, I just wonder why its so obvious that the smoothness disappears after a while.

 

Or could it be because of the effect of the Xado/Turbo products wearing off :confused:

Ucal-Mikuni BS29 Contant Velocity Carburator

 

Understanding the Basic ...

 

 

1: Starter Circuit : Constant Velocity Carburetor

 

http://www.singaporebikes.com/forums/attachment.php?attachmentid=205613&d=1306419848

 

Function

The function of starter circuit is to provide rich air fuel mixture on starting / cold starting. At cold engine

condition the air is dense also the engine parts are cold enough this does not allow the petrol to

vaporize properly this leads to starting trouble.

 

Construction

The Starter Circuit consists of a starter jet and a plunger. The starter jet is used to meter the fuel and a

plunger that opens an air passage from the inlet of the carburetor (underneath the diaphragm) which

passes the mixture to the mainfold.

 

Working

On pulling the choke lever the plunger is lifted by a cable. This uncovers the fuel passage that leads to

the starter jet, air inlet passage and the outlet passage towards the manifold.

This creates enough suction to draw fuel up from the bowl into the mixing chamber (below the plunger).

Here the fuel is mixed with the air and the mixture is drawn into the engine through the outlet passage.

 

 

2: Pilot Circuit: Constant Velocity Carburetor

 

http://www.singaporebikes.com/forums/attachment.php?attachmentid=205618&d=1306420012

 

Function

The pilot circuit provides the air fuel mixture at idling when not enough air is being drawn through the

carburettor to cause the main circuit to operate.

 

Construction

The pilot circuit consists of pilot jet, pilot air jet and volume control screw. The pilot jet meters the fuel

and the pilot air jet meters the air quantity. The volume control (VC) screw controls the amount of air fuel

mixture flowing through the pilot outlet.

 

Working

As the air enters the pilot air inlet the fuel is metered by pilot jet and air quantity is metered by pilot air

jet. The atomized / vaporized mixture is discharged through the pilot outlet. The pilot outlet is located on

the manifold side of the carburettor. Since the throttle valve is almost at fully closed position, air fuel

mixture is supplied mainly by pilot outlet only. Air fuel mixture volume is adjusted by volume control (VC)

screw and mixture becomes lean when volume control (VC) screw turned clockwise and rich when it is

turned Anticlockwise direction.

 

 

3: Progression Circuit : Constant Velocity Carburetor

 

http://www.singaporebikes.com/forums/attachment.php?attachmentid=205619&d=1306420018

 

Function

The progression circuit provides the air / fuel mixture at small throttle opening when pilot circuit is still

working but unable to meet the engine demands on small throttle opening.

 

Construction

The progression circuit follows the path of pilot circuit and the construction is same as that of pilot

circuit.

 

Working

As like pilot circuit the fuel is metered by pilot jet and air volume is metered by pilot air jet. This mixture

in vaporized / atomized form is discharged through the bypass ports when the butterfly valve is opened

from idling further.

 

 

4: Main Circuit : Constant Velocity Carburetor

 

http://www.singaporebikes.com/forums/attachment.php?attachmentid=205616&d=1306420001

 

Function

The Main Circuit provides air fuel mixture by lifting up the piston valve in direct proportion to the engine demand.

This assures the correct venture size & air velocity throughout the mid range operation of the engine.

 

Construction

This circuit consists of jet needle, needle jet and main jet.

To assist in atomization an air bleed circuit is incorporated in the main metering system and it aids fuel vaporization

by introducing the air into the fuel before it enters the main air stream.

Towards Engine Air Inlet for main jet

The piston valve movement is controlled by spring and carburettor venture vacuum which is generated

below the piston valve diaphragm.

 

Working

When the butterfly valve is opened and air flow through the venturi increases, the air pressure in the

venturi (and the upper chamber) decreases.

As the atmospheric pressure in the bottom chamber is greater than the venturi pressure above the

diaphragm, the piston valve along with jet needle is pushed up and more air fuel mixture is drawn into

the engine from main jet through needle jet into the main air stream.

When the butterfly valve is closed, air flow through the venturi decreases; air pressure in the venturi

increases and approaches atmospheric pressure, & the spring pushes the piston valve along with jet

needle down.

Now I know it's normal to get a smoother bike after servicing and changing the oil, I just wonder why its so obvious that the smoothness disappears after a while.

 

Or could it be because of the effect of the Xado/Turbo products wearing off :confused:

 

 

hmmm .. you can try changing other EO to have a feel if it's the same feeling you encountered. Every bike has it's own charactors and every rider has their own feel of their bike ...

 

It's also how the way we ride our bike too to have the bike to its top performance ...

 

eg only : riding slow does not mean it's good for the engine and whacking the bike also does not mean it's harm the engine too.

It's all about the engine itself from the very beginning ...

 

 

"Any rebuilt or new engine has to go through a break in process. Each piece of moving metal must get to know and fit with the piece of metal it is moving against. Usually, the manufacturers put a sticker on the speedometer or tachometer telling you to take it easy for 600 miles or so. Your buddy says "If you want to run it hard, break it in hard." As you might expect, the truth is not on the right hand or the left but, in the center.

 

The problem is this. All this rubbing produces heat, which can cause oil to fail, which can cause a piston to seize to a cylinder wall. On the other hand, if there is not enough rubbing, the piston rings will not seat right with the cylinder walls. If this happens the engine will not reach it's full power potential. If the only new parts are piston and rings, as in an engine rebuild, we only have to worry about heat build up from the new parts. If the entire engine is new, the heat built up is even greater, because all the parts are new.

 

Yes, it is true that we have much better machining and quality control on new motorcycle engines, then we did in the past but, moving parts still have to wear in. If you have better, harder metal, it will take longer then if you have poorer, softer metal. Years ago I decided to bore my BMW motorcycle to the first oversize. After a hundred miles of break-in I started to ride normally, which is to say FAST ! Well, the bike just was not running right. I re-jetted the carb and it started to run OK. Another hundred miles passed and I had to rejet again. This went on for over one thousand miles. After the last re-jetting I realized I had just put the stock jets back in ! It took better then 1100 miles for those rings to break-in. The steel used in BMW motorcycles is very hard !

 

On one hand, if you run the bike too easy, you run the risk of the cylinder walls glazing over and then, maybe, never seating properly. On the other hand, if you run the bike too hard, you run the risk of engine seizure. I suspect, that even if you do glaze the cylinder walls over, if your run the engine hard enough and long enough, the rings will seat. However, this may take a thousand miles, or more, to do.

 

So what's a biker to do ? Well, a compromise is in order. This is what I do with a freshly rebuilt engine. It will work on new engines too. On a straight, deserted road, I put the bike in second or third gear and accelerate with wide open throttle to about one or two thousand RPM BELOW red line. I then shut the throttle and coast down, in gear, to two thousand RPM or so. I then do it again. I do this about ten times. Then I ride around for a while at an easy pace. I do this several times, if possible. This seats the rings without overheating the engine." .. (dan's motorcycle)

[ORen]

@mjbs64, thank you for the reply, I thought about changing the oil, just got lazy to research which i could use. In any case i think I will have to during my trip, I don;t think I'll find the one I use here, everywhere I go.

Agree it's all about the riding style. That's why I am a liiiiittle bit concerned. Because i don;t think it's the bike. I think it's probably me. I don't know.. i didn't make any massive change in my riding style, but who knows, maybe I did..

Maybe I'm making a big deal out of something everyone experiences that's why I wanted feedback from this group. I know the slightest change on my bike, either feeling or sound or visual difference as soon as i notice it, I need to have an explanation for it.

Otherwise I keep thinking about it all the time

 

Also since i noticed this a month ago or so, before my last servicing, I kept paying attention and the smoothness was perfect after the servicing and recently, as I hit 1500km with this oil change, the slight roughness is coming back.

But I'll keep monitoring.. and anyway my 10k km servicing will be done sometime soon so we'll see then if anything is uncovered..
