Hi guys, my friend who owns an CBZ Xtreme 2011 model has an rather unusual problem with his bike.
1.While riding during rains, the bike tends to jerk as if there is no petrol and does not start, but starts after the rain stops.

2. Strange sound coming from the handlebar, where the Xtreme logo is embraced.We had put thermocol but even then the issue is not yet resolved.

3.Knocking sound and both the suspension feels rock hard while going over a pothole.

Went to HH service centre yesterday, the mechanic said engine needs to be opened to clean the carbon deposits in the head.And about the problem mentiones in Point No.1, probably the water is entering through the tank.Confused.
The bike was returned within 8 hours but it has not rained yet since yesterday, we are yet to find out whether the issue is corrected or not.
And the noise is still there near the handle even after the service.

Any inputs?

Some one here(IIRC, Sooraj_vs) has tried KBX pads and he's satisified with the results, but they'd wear out soon.

But I don't feel my Hunk's brakes to be too bad as you guys mentioned, may be its poor compared to Apache. Check the following anyways,
- check if the brake fluid is too old, when did you change it last?
- check the condition of master cylinder piston with the help of a mechanic, if the oil pressure is leaking thru pistons you'll not get the right braking
- rubbing the brake pads to remove glazing would improve braking, see the link here

My disc was starting giving me trouble at 5000km, so there no point of changing brake fluid at that time (correct me if i am wrong)..

Dump the OE brake pads and install ANL or KBX (available only for the front i think) - i am using ANL on the rear and they are way better than even ASK pads .

So ANL on the rear and KBX on the front ?? whats the lifetime of these pads??

Also if you can change the crap OE MRF tyres to SIRAC STREET like me and see the magic - when i first bought this bike its brake sucked balls even i thought of installing the RTR disc assembly like you - just install these two and i bet you will forget about the poor braking .
Rear MRF tyre sucks big time.its very slippery in wet floor or road.waiting to get it finish its life.how long will it last btw ?

I tried to set the carb using sibuns guide but my RPM needle is not working need to repair it before i try sibuns guide again.So i have set it 2.5 turn out think thats the factory setting but i dont know .

KBX pads come from the front only i think - i am using ANL in the back and ASK in the front -

Is braking response better than stock one? and u didnt mention the changing period .mine is 12.5K and i guess its high time though my front brake is good and rear one is OK (as expected in most cases).
No offence but i was interested in replacing my disc plate with something compatible,i dnt like its silver color

the OE tyre is hard compound will last a while mine lasted for like 25K+ and in an emergency its your worst enemy - if i were you i would switch to SIRAC street immediately and keep the MRF as backup only - the OE tyres will probably kill you sooner rather than later esp. if its raining .

I doubt so,i guess its gonna last even longer .i was planning for leh-spiti ride since ages but cannot find time-company for the same.wont go into it without changing my rubber . btw is it TL ?? and cost ??
Most of the braking comes from the front only so change both front and rear as a pair for best results .

brand new bike + no disc brake + noob driver = this :



rear ended some truck at high speed the driver and the passenger gone instantly .

I dont know how but this guy walked away without a scratch :



maybe run over by a train ?

Did a thorough search on C.A. road yesterday (I live in Nagpur, Maharashtra) and finally found the rare Motul 3000 4T Plus (20W40).
A question... is 15W50 grade higher and better than 20W40 ? A shopkeeper kept trying to sell me that.
Also I could not find that Ngk G Power spark plug... Some shops had them but it was for splendor's and other low segment bikes.... Also one shopkeeper told me that he used to keep them but now has stopped cause of a vast china market in NGK's (Can't distinguish the genuine one if both kept aside).
So is there any substitute for the NGK G Power or should I stick to the stock Champion one

I have seen a lot of Xtreme that stops like that in rain - mine used to do that when it was new .

Hi guys, my friend who owns an CBZ Xtreme 2011 model has an rather unusual problem with his bike.
1.While riding during rains, the bike tends to jerk as if there is no petrol and does not start, but starts after the rain stops.
Check the ignition switch connector below the ignition switch. If there is water on the connector then the above problem will occur.
2. Strange sound coming from the handlebar, where the Xtreme logo is embraced.We had put thermocol but even then the issue is not yet resolved.
Open the cover and see if sound is coming and then report back.
3.Knocking sound and both the suspension feels rock hard while going over a pothole.
Change the front shocker oil and the rear suspension is hard by default. It is the suspension which gives the excellent handling of extreme.However you can adjust to a softer setting. Some batches had also defective rear shock. Check with service center and change under warranty.

Went to HH service centre yesterday, the mechanic said engine needs to be opened to clean the carbon deposits in the head.And about the problem mentiones in Point No.1, probably the water is entering through the tank.Confused.

Yes, carbon deposits in head is a major reason of knocking. Are you getting adulterated petrol in your area.Also use IFTEX system 2-3. I am using it and is greatly beneficial as it contains detergent.
Any inputs?

Yeah like you predicted earlier and those marks are "honing" marks ? i thought inside the bore should be smooth with no marks like that .

The SC mech told me they dont rebore only install new bore kits - its like their standard practice or something - only that head mech in vellore was ready to change just the rings - i even called some other SC and they were like " better go for complete overhaul" .
No service center wants to go for boring and overhaul. They only wants to change parts. Its because they get 15% commission with new parts. So more value of parts, more profit and also more labor charge.
For the work you have done they used parts of Rs.4000. So there commission is Rs. 600 and labor charge of Rs.700.
For your information the engine oil of hero honda which is Rs.215 cost Rs. 170 to SVC. So they are always eager to change engine oil and do not alow any other oil. Hero honda clearly mentions in manual that any oil of 10W 30 grade can be used but svc do not allow.
So a total of Rs. 1300 they made by just changing the bore kit.
So it was the oil seeping through the rings gap that was spoiling the valves ? that head mech in vellore already knew of this [problem yet he didnt change the rings the second time the bike lost compression - he just put new valves and sent me home that bugger .

This particular SC in kanchipuram is a known CHOR SC - long back they even tried to sell me a accident bike as new - they once filled in only half a lt of engine oil during service - failed to set the tappet correctly even after multiple attempts - the list is endless - so you know i would never have given my ride to them ever - but that mail that i sent to hero and the GM guys response was what made me change my mind - also i was getting tired of running around .

completed 200Kms with the new bore and some observations :

1) earlier with the old bore the genuine honda 10w30 felt great but on this new bore i dont see much diff. between the hero oil and this honda one.
Its because your compression has increased.
2)The engine heats up a lot like even after just 20Kms it fells like it has done 70Kms or more .
Same as above.
3)The engine feels like its "free" already - feels like it require no running in - also i see little to no diff. in the kicker pressure - the kicker compression is not all that great - i checked it with a old xtreme that came to the SC its kicker was much harder to kick .
Compression increase will always make the engine feel free. Check the tappet with feeler gauge. If the tappet clearance is low your kick will feel soft. The major problem of soft kick is caused by incorrectly set tappets. After 1000 km take it to good SVC and tell them to set the tappets using feeler gauge. You kick will become hard.
But the bike flies like anything it feels like one twist of the throttle and it will do 90km/hr in no time .

Hello guys,
I have some queries regarding my bike (xtreme 2010 model -black red)

Which Engine oil is most recommended for our bike? I'm thinking of Motul 20W40, but could not locate any dealer in Nagpur selling it (even online). So if you have any, please tell me.
Use Motul 10W 30 or any good 10W 30 oil. Else use SHELL 10W 40 SS oil and you will see the difference. Do not use 20W 40.
Do engine oil supplements work? If yes then which to prefer?
Never.
Is Ngk Iridium Spark plug good for our bike and will it need any air-fuel mixture setting done when installed? Or should I stick to the stock Spark plug?
Do not use NGK iridium. They are quite expensive and also not available for extreme. Use g-power, best plugs at affordable price.
Regarding AIR- FUEL setting ensure that engine is not tuned rich as these plug easily gets damaged at rich setting.
What do you think about installing KnN air filter? What are it's pro's and con's
Do not use as it causes more damage than benefit.
Also, any permanent solution for the front disc problem common in all xtreme's?
There is no problem in extreme brakes. Do a complete overhaul and see the difference. In my next post i will mention how to do a complete overhaul of front disc.
Thanks in adv
Have a riding day

need some advice from experienced xbhpians here .

1. What is the life of the spark plug ? my cbz is 2 yrs old 13k kms on odo . is it time to change the plug ?

2. when must i replace brake pads and brake oil for the front disc ?

Any cbz owners in south bangalore ?

Thanks s1d , will replace it shortly , But my mechanic says front discs are fine , but i am not happy with it .

At first i thought this was regular wear out and brakes are not as new as it was , but i rode a few other bikes like pulsar 220 , gs 150r , apache which have done more than 20k + kms , their discs are really good. its like pressing a button to brake.

Any one here tried apache or other pads on CBZ ? wil it fit without any modifications ?

If the pads are still good, then start by replacing the oil and the brake hoses. Ensure the brakes are bled and there is no air trapped. You can also get the brakes overhauled and replace any other parts in the brake system that could b worn out. This will give you a good 'bite'.
