lol @ akshay

I hope u allow me to get some help on my bike too :P

llakhs !!!!!!!!!!!!!!!!!!
i think i have a misdefinition of dyno
i thought its a small electronic device( short form of a dynamo metre)
neways then how can i tune it
ne diys........

Dude, this is what is called as DYNO!

hmmmm
dyno ! !
but tread mill or treado would be more relative
newaus . . .
ne diys for carb tuning guyz ?

For carb tuning, spark plug reading is good enough!

is there anything else that needs regular tuning then the carburettor ?

what if i opened up airbox cover on my fz & make mixture rich using af ratio screw on the carb only(mikuni bs -26) ,can it run ok ,
if you have seen the air box setup on fz under the seat , there is no place for good amount of air to go in ,even intake sound changes when u remove the seat and revv it

You will not get any increase in power by just removing the cover. Besides, if you remove the cover, the whole purpose of having a filter is defeated since the carb will be sucking in air directly!! Have you opened up the airfilter box and seen the setup?

^+1

the stock air filter is designed such as to allow minimum amount of dirt to enter the engine .
if you remove the filter snorkel there will be a change in sound because of the change in flow path of the air . you will not be gaining any performance by this.
just running an extremely rich mixture for no reason wont give you anything too .

Hi Guys .. I came across this thread today .. I have little knowledge about bike modifications and i found good information here in this thread. I have a 2003 CBZ Classic with 23000 km in the odo. I have kept the bike idle for 5 years from 2005 to 2009 as I was out. I started riding it again from 2009 itself. The condition of the bike is good. I did some small changes to it myself .. I changed the stock plug to NGK iridium, modded and changed the airfilter to K&N and also put a original split-fire cable as the stock one got cut .. .. Anyways, I did not do upjetting or exhaust modification as I don't want to loose the beauty and reliability of my classic. I also changed chain spoket set with a new stock one and the clutch too. Cleaned the curb myself and adjusted the tapit by an mechanic here at Kolkaka. Am good with the power delivery of the bike as I am not into speed run or stunting and mainly use the bike for weekend trips of 150-250 kms around Kolkata.

I am facing few problems with classic recently and seeking for your help here.

1. The stock lights are really poor and want to do something with it. I have few options but need your help in terms of finding the best suitable. Options are:

A) Change to HID - Cost is not the factor, but there are issues associated with it .. I need to convert the electrical to DC. Need to put a 9AmpH or 14 AmpH battery and for that need to alter the existing battery case. Also for charging the battery, perhaps needs to change the power direction from magneto to battery and headlamp. As for the existing setup, 2 points go to the battery charger and 3 points for the headlamp. Simply switching it won't help as it is not plug n play setup. If I don't do this, the battery will drain in couple of hours.Though the wattage consumed by HID is 35 but switching it on and off couple of times will choke the battery to death.

B) Change the magneto to generate more wattage so it can power 55/60 or 90/100 halogen. But there is no available plug n play magneto in the market. Only option is to rewind the coils. The issues associated to this is, it has to be done by a experienced electrician... for this perhaps 40mm gauge copper wire is suitable but am not sure. Currently, 34mm gauge copper wire is used for the coils. After the rewinding, I have to change the entire electrical as I don't think 7 year old wires are capable of handling the extra load. The biggest problem for this entire staff is finding a good auto electrician to do the entire job. I can start doing this by myself but perhaps it will take me a year to complete the job... So, If anyone has any idea of an good auto electrician and mechanic, Please let me know.


2. My second problem is, after fitting the K&N, the engine has become lean, generating excessive heat and I am not able to fine tune it .. Need someone to help me fix this quickly otherwise it's gonna hurt the engine a lot.


3. Third problem is, both of the rims has some little bends .. and I am not able to find a good mach to fix it ... and it's also causing the fron disk to get a li'l jammed and sometimes given trouble to breaking too.

So friends these are my issues .... I know there are experience ppl here and expecting the reply from the gurus here .. Thanks a lot ..

Untrue

I don't feel this is entirely accurate and people who write articles such as this must not write based on friend's experiences and hear-say.

I ride a pulsar 220 and it was completely stock until today, I had bought an extra large kn filter, iridium plugs and plug wires.. totally it costed a little over 4k. But believe me I CAN feel a difference in the acceleration of the bike, I don't know what difference a dyno will show but I did feel the bike was quicker and I'm not misled by the extra sound. That's the only thing I didn't like.That horrendous noise like an obese red Indian farting or like a Honda Dio...both are same!

The key is not to expect much and you will surely find some gains which only the person who rides the bike regularly can feel. These mods are the first step in my quest for more power. Perhaps in a month or two I will visit Joel and get some serious mods done. But all the same one cannot term these beginner level mods as useless.

peace!

RogueRider,

Can you post some pics of the K-N filer assembly?
Wan't to know how it fits.. or whether it kind of protrudes out?
Also, what is that you comment abou the sound ? Exhaust note got changed due to air filter?

I myself am planning to get a K-N for my P180(2004) and want to know about the issues (if any) beforehand.

Cheers!

The kn filter i bought was bigger than the normal one but there was alot of space left even after installing this filter. I could take a pic but it beats the point as my bike is not the same as yours, the mechanic removed the stock airfilter with its box. I think if I clean it once in 3 months it'll do just fine. It doesn't protrude at all.

The exhaust note may not change but there is quite an increase in the noise from the air filter as more air is being sucked in.Don't worry it's not that loud and if you want it extra quiet you can fix the kn filter in the stock filter box.

peace!

K&N

K&N are more porous than stock OEM filters.It means the K&N can allow more larger particles in to your engine which will grind your piston ,rings and bore leading to early loss of compression.The best filters have been found to be Paper filters which at worst may clog but will not allow large dirt particles inside your engine. OEM filters are the best.The OEM filters are designed for specific Engine and must comply as per ARAI certification.

DUDE IS THIS A JOKE????

i am personally using a k&n and have had no problems whatsoever. if the k&n is not fitted properly, dirt escape in from the sides but never through filter.

if this was true then i would have had a damaged carb long time ago.

the k&n simply increases the effective surface area for dirt colection and hence requires lower air pressure to allow air thru it.
