Err...there's no stock setting as such IMO. It depends on atleast your intake & condition of airfilter.

Means, you're running it leaner. Also I guess 3.5 turns is too much. I'm assuming it should be 1.5 to 1.75, not sure, I could be wrong though.

You need to talk to H.H.A.S.S patiently & then tighten up things. Otherwise you need to take it to a local garage or worst case, listen & learn patiently as where the noises are coming from, which is best IMO.

Ordinary, regular Petrol from a good fuel station is just perfect. Anything more than is welcome, but not needed.

You need this type of fuel only on engines with high compression ratio, for example, Ninja 250R, most SBKs or say compression ratio more than 10.5 or so. I believe CBZ has somewhere in 9.x for which ordinary petrol is suffice.

Always use ONLY Unleaded/normal Petrols i.e. 87octane from a good pump to keep the bike healthy, no premium fuels. And always stick with one good fuel pump.

All engines gets hotter, if you feel hot air in your feet while riding then you can consider it as a hotter. Best to check the temperature with a same segment other bike with a same average run. It mostly depends on engine oil, and its level too.

Just go to the service center and ask the "supervisor" to allow/permit the service center mechanic to check the setting on a brand new vehicle and give the results to you. I believe they won't say NO.
Since Xtreme has Keihin carb the setting would be between 1~3 turns out. My friends Xtreme has default setting of 1 3/4 turns out, not spot on though.
I am running 2 turns out on my Unicorn which shares everything including the carb. My friends FAZER has mikuni carb and the stock setting is 4.5 turns out.
Why can't you tune it for yourself oldschool method described in this website. After that X turns setting test it for a day, then test X+1 turns for a day and X-1 turns for another day, then use that setting which feels good for you.

I can feel the same thing on my Unicorn when I use SPEED(although its just normal fuel with some additives) and I am continuing to use it Plus I am getting 2~3kms extra per litre although the price difference nullifies the advantage in mileage, but not the smoothness. when you are riding uphill with a pillion, you can feel some knocking sound(very obvious on lower CC vehicles) and I had read somewhere that if you use higher Octane fuel you won't get that knocking sound(can't explain the science behind it, it has something to do with compression etc). Although everyone says normal petrol would suffice, there would be no prob in using premium fuels if you can obviously feel the difference using them right.

wow!!!! some great replies.

first of all to every one...after svc guys tuned my carb i got sluggish pick up then i tried it myself & it was approx 3.5 turns 360 degree & everything was ok. 360degree turn means 1full turn isnt it??after another servicing svc huys did the tuning again & again i got sluggish pick up & engine was getting hotter. then i counted the turns..it was full 2 turns 360degree. after then i revert it back to 3.5turns 360degree. though i think i'm wrong at something but my bike is flawless incase of smoothness & pickup. my current mileage is 43-44kmpl in the city & 48-52 on highway. remember that i live in Bangladesh where fuel quality is comparatively very lower than india & almost everyone in here gets very less mileage such as other cbzx owners get 30-35kmpl max. my spark plug color i think is little deep brown. i know rich setting would make it black. so please help me about tuning.

@aargee...bro please forget about the svc in BD.there is only one & they know nothing.now i go to my own mechanic. thanks bro for your response.

@soumen.sam people say that octane can harm the engine in the long run. thats why asked either to use petrol or octane?? i think my tool box is not making any sound. ok i'll try greasing the hole. what is chain guard??? you mean chain cover??? thanks bro for your awesome response

@sandeepcf its only 1 3/4 turns???? 360 degree turn??? i tuned my bike by following bike advice website. after taking into account you peoples response i'll definitely try to follow your advice taking X+-1 turn a day . well i feel better with octane. so now i'm assuming octane doesn't cause any harm to the engine in the long run. thanks so much for your reply.

by the way cbzx's compression ratio is 9.1:1

i have another question
i think the stock bulb isnt good enough for me.i cant go for HID.does any other bikes lamp can be any better than my stock halonix bulb??

thanks again to everyone

Go through this thread, you'll find quite a lot of information - http://www.xbhp.com/talkies/universa...g-hid-etc.html

Dude octane number is resistance capacity of the fuel to self-igniting. Octane defines the quality of the fuel. Higher Octane fuels burns more good and left less remaining than ordinary fuels. Without octane no fuel can burn. Even diesel have the octane also. But in India like countries those fuel we see calming as higher octane like speed 92, speed 97 leaded fuels those have lees actual octane and more fuel additives, so that with those people get better performance but those increase the CO level or Carbon deposit greater than unleaded fuel, so why manufacturer recommend to use unleaded fuel.



And best thing is to stick with the stock bulbs.

@Soumen.sam: Why is it best to stick to stock bulbs?

The bike itself manufacture with some specification. Volt to amp all are preciously calculated to provide the reliability.

Whatever lighting enhancement you go for, definitely you will get problem in future. Shorter battery life, low battery risk, wiring system may damage, HID also may damage the head light insight reflector due to extreme heat etc.

I saw many people who ripped of those HIDs after a few days of using.

Lets say you are on a long ride with a HID kit installed. Suddenly the bulb blown. What do you do? Also you will loose the full wiring system warranty.

Those low range HIDs comes around 1500 to 2k their focus, accuracy are far less than the stock light. They just provide a white light which always bother front coming riders.

So as per me better than HIDs if you want more light, keep the stock as it is and put a good separate fog light.

Wow! You must have never visited the Let there be light thread.
And how do you think the fog lamp will run when you do nothing to charge the battery more?

The H3 lamp is called the Fog lamp. These lamps are single filament lamps & as the name suggests increases the visibility during foggy conditions by giving brighter yellow lights.(halonix website), their wattage starts from 55w.
so 2X55w is a massive load and the bike cannot handle it.
Replacing a bulb is a matter of 10 min if you have a screwdriver, spanner. So in case of blow out carrying an extra lamp would simply solve the problem.
