Hi All,

re: CBZ xtreme / Hunk

When is the new xtreme expected to be available in showrooms ? I have not started seeing any new ones on the roads.

re: CBZ xtreme / Hunk

Veedol Take off 4t Premium - 10W30.
As of now this is the best oil for xtreme/Hunk at this price(~Rs.250/-).
Get two bottles as one bottle is 900ml, xtreme needs 1000ml if you tilt the bike (to get leftover oil from engine).Otherwise for normal draining 900ml will also do.

Regarding the bike then it is better if we can discuss about it over phone.

Re: spped and vibration problem for my CBZ Xtreme.. Help!!!!!!

Pritam could you please elaborate more on the source of the vibration, knowing that would be of great help in pin pointing your issue.

Also how many kms is the bike done? Any parts replaced during the service?

Top speed can be effected due to several reasons ( I take it that your engine is in good shape as you say you have serviced the bike regularly)

1. Worn out chain/sprockets
2. Worn out tyres
3. Gear shifting pattern

And various other things. Please answer the above questions as one can proceed better with that info

re: CBZ xtreme / Hunk

Its just been announced, even the price hasn't been declared yet, I think it'll take minimum 3-4months to hit the showroom.

re: CBZ xtreme / Hunk

So finally i got some time to clean my carb , the problems assosiated with were

1. Bike getting off during idling at traffic , which is irritating
2. Mileage and performance is affected ( decreased )
3. Rough idling and uneven strokes

So i made a short DIY with help of members , @paul.1911 , @shoeb.2015 and @sibun

1. Open right side body panel which houses the battery



2. Turn off fuel & Apply bit of force and un-screw the float drain screw , this is bit tight but not very hard , spray some WD40 beforehand to make it loose


3. Loosen carb side and air box side hose clamps , these are clips with screws easily unscrewed



4. Remove all hoses , choke cable , accelerator cable

5. Now only TPS should be connected with carb and then slowly pry out carb from the insulators



6.Now pinch TPS connector (white color) , if you are unable to remove it using hands, use pliers to gently press on clip and slide it out ( GENTLY )


7. Now remove the lower float screws (3 nos ) , They are hard to remove if you are unable to remove them and screwdriver is slipping , take it to mech , mech had T shaped screw driver and gave bit of tap on screws to get them free

8. Inspect float for any debris , clean using warm tide solution or carb cleaner


8.Now remove the float pin , float and float valve . Shake the plastic part and it should not have any petrol inside. Float valve rubber should be smooth .



9. Unscrew pilot jet and dip it in acetone ( nail polish remover ) or blast it using carb cleaner



10. Remove main jet and clean it , pilot jet is 35 and main jet is 128

11. Dry the jets under sun for a while or use hair dryer to remove any traces of acetone

12. Reassemble the jets , float valve , float and pin


13.Check float gasket but DO NOT REMOVE IT , refit float back , lube screws and screw it back


14.Reconnect TPS ,acc cable , choke cable and hoses

15. Turn fuel on and start the bike


But mine didnt start and i tried to crank it numerous time but it didnt fire up . So I tried to roll start but even then it didnt start . So took it to mech where he said there is no spark at all , removed the red plug cap and tried cranking even then no spark. I was really tensed as this was a new problem . I called up @sibun and he said to check below tank for loose CDI and power coil wires as they might get loose while removing carb.

SO i removed fuel tank a bit and YES THE WIRES FROM CDI WERE BIT LOOSE , so fitted them back securely , another thing caught my eye that a connector from fuse wiring covered with white rubber was also removed , this was accidentally removed while taking out side panel. Refitted it but repeated cranking made battery dead . Pushed started it and within 2-3mt it came back to life

I let it idle for 10-15 min so that batt gains some charge

Now bike idles very smoothly and strokes are nice and even , acceleration is improved.

Thanks to @sibun who exactly told root of the problem , SVC idiots were saying my stator has given up , Thanks brother you really helped me today.

Also yes our battery isnt much powerful if bike doesnt start up in 3-4 cranks , dont use self as it will drain battery completely like mine.

The connector near fuse box has 4 wires white yellow red and cant recall last one
1.if white is removed the bike wont crank
2.if yellow is removed the fuel gauge will drop with increase in speed
3.if red is removed the fuel level wont drop (this doesnt mean astounding FE )


So i hope this helps ppl and again thanks @sibun , @Paul , @shoeb you guys really made me find the problem and solve it in best way possible

re: CBZ xtreme / Hunk

Hi All,
I recently bought a 2010 model Hunk which has done 27,000+ Km and is in excellent (paint and looks) condition. The ride is very smooth, i changed the engine oil to Petronas Sprinta 10w40 Fully synthetic (i know the grade is not right will change it to 10w30) also the airfilter.
The issue I am facing is the bike wont go beyond the speed of 70/kmph. Can any one please tell me what could be the issue. I know the clutch is good as there is no slipage, wondering what could be wrong.

Any help would be highly appreciable.

re: CBZ xtreme / Hunk

Get the Carb and tank cleaned and see if that helps, check the chain sprocket for wear too. 10w40 grade in synthetic isn't a bad oil for hunk, u can use it no problem.

re: CBZ xtreme / Hunk

Got the carburetor cleaned changed the chain and sprockets. Both the sprockets were worn out. Lot of soil debris deposits cleaned it. Bike is now flying

Check the spark plug too, I'm sure the previous owner hasnt changed in the past 27k km.
