Re: CBZ xtreme / Hunk

Any suggestions please.

Re: CBZ xtreme / Hunk

If you find good effect then you can continue using it.
Since your bike has crossed 50k your engine clearance will have slightly increased, so the nulon is helping in smoothening the engine.
Shoeb has replied, and he also gave you the part number. So good to go.



Updates on my extreme:-

Nothing good. Bike has been running good but loss of torque is felt.

Due to two times opening of engine for gear problem and in spite of my request to change the rings while opening, ring change was not carried out. As a result now bike is low on compression and thus torque.

Both the tyres need change, engine needs a rebore and clutch although feels new, once rebore is done and compression is increased will require change, so needs to be changed. All in all a case of 8k expenditure. Bike has crossed 50k and if engine was not opened or if rings were changed while opening this re-bore wouldn't have been required.

In two minds whether to overhaul or sell and get a ZMR.

Re: CBZ xtreme / Hunk

My Vote, go for ZMR.....!!!! would be a perfect upgrade from 150CC all rounder to 220cc all rounder.

Re: CBZ xtreme / Hunk

Unfortunately no. Will not go for a ZMR now. Its because i weighed the pros and cons.

Now i will give you a perspective.

My is 3.2 years old. Has run 50k but let me tell you everything feels new. You use the switch, feels new, use brake, feels new, look at instrument console feels new, Ride it and the chassis feels new and taut.

Now let me come to problems:-
1. Engine oil consumption- it is not high but still a loss of 150ml in 2000 km. My Joy when had bought it here for three weeks, on highways was operated with full throttle most of time and still the oil level was perfect. So no excuse for extreme on this. This happened because the buggers at showroom didn't change the rings while installing back engine due to gear problem. Now no difference in changing ring as i can hear ring flutter at high rpm which indicates the grooves in piston are worn.

Will rebore it as the extreme has a very thick liner and can be bored four oversizes. Besides throwing away the bore with so much thick liner is waste of material. Moreover usually in boring main problem is the guy doing it, but i found out a guy who does boring and honing with boring machine and honing machines. His work is amazing.

2. Clutch plates- Even to this day the clutch feel is like new, and no slipping and no judder. But have to change as after boring the compression will increase and also power and thus will eat of the plates. SO changing it at a time is better.

3. Tyres- Both set require replacement, but this shouldn't be counted as maintenance as any bike you buy will require change of tyres.


So basically the parts needed to be changed are:-
1. Boring with new piston - COst Rs. 1200
2. Clutch plates- Rs. 1350
3. Tyres- Rs. 4000
4. Rocker arms- Rs. 490.

Thats all at 50k.

Now what will be the loss.
I bought this bike for 72k on road. Today if i sell then at most at 40k. Depreciation = Rs. 32k/3= 10.66k per year.

Now suppose i buy a ZMR. I have to invest 70k extra which i will take loan. The installment for 3 year loan comes to 2100 for staff loan.

Now any bike i buy the depreciation will start immediately. Also as per my running bike will require work in three years like above. So in three years the ZMR will sell for around 60k. So the depreciation is 50k/3= 16,666.33. that almost equals to Rs. 1390 per month.

So in effect my fixed monthly expenditure is 2100+1390= 3490.

But if i keep the extreme, since three years has ended, depreciation will slow down. In fact even i sell after 1.5 years still also rate will almost be same or along 35-37k.

So practically any bike you buy new , the first three years it depreciates rapidly. After that it stabilizes.

So i have a virtually new bike. After i do these works i can ride for another 50k without problem. Even will sell at same rate as now after 1 year.

As for the bike it is extremely good. Has been returning 53-56 kpl at speeds between 75-85 kph.

Extremely reliable. Have ridden at nights on highways and have reached home at 10 PM after riding 170 km and has no problems.

Important thing is that the headlight even though its AC is superb.

Pulls insane. i am yet to see another extreme pulling like this. keeping rpm above 6k for most of time has made it so.

Have touched 124 tops, which is amazing almost in bigger bikes territories.

Looks New. Parked and all will not believe it as three years bike.

Moreover that emotional bonding.

But when ever i see a new ZMR or ride one i feel instantly attracted to it.

Sometimes head and mind fight against each other.

Will do the work and ride it for another year. And rest assured with my magic working on engine, it will run better than before.

Whoever wants to upgrade after three years can look at above calculation. Usually after 4-5 years selling is beneficial.

Re: CBZ xtreme / Hunk

Hello fellow members,

i am new on this forum, had issues with my motorcycle, googled for it, and ended up here...
couldn't go through all the pages of this thread for my issues, so will post all details here..

to start with, i am a noob in this domain, so forgive me for my lack of knowledge.
i have buyed a 2nd hand CBZ Xtreme 2011 make 1 week back...
pics are below:








Sorry, for the image resolutions.
I have a few concerns about the bike:

1. Pick-Up: The pickup is very bad, 0-50 kmph in 8-10 seconds approx (with regular change in gears)... i am keeping the rpm although within 5k, as, i think going more further at this stage will damage the engine. Also, this slow pickup is in all gears. Could this be an issue with clutch plate?
2. Engine Heat Up: I just ride the bike for 4-6 km, on a normal day (little cloudy), and yet, the engine heats up much, in my opinion, this might be due to the low pick-up issue.
3. Shocker Adjustment: I also feel sometimes that the shocker is a bit worn off, whenever few bumps or pits come on the way, it feels as if the back shocker is loose and is very very jumpy.

The bike has run around 54000 kms...
Due to above performance factors, i am not quite happy with the bike,
the bike hasn't been services yet in around 3 months.
Also, i tried to get to max speed just to check how much it goes, and i just went far as 80kmph, and that too on a less busy highway.


anyone, who could help me with these situations?

also, what would it cost to get a full servicing done in a hero authorized service center....??

Re: CBZ xtreme / Hunk

All the best for ovehaul Sibun. What about rear shocks, i remember you mentioning about that sometime back, you changed them?
I couldn't change them yet, I think I got used to the shock feel

Coming to my bike, mileage was always a worry for me. I started using Shell normal petrol these days and started shifting gears in a much low RPM.
If I wanted to ride bit faster, still I shift below 4k RPM and reach top gear as early as possible and start building speed from there.
I am getting a more consistent mileage now, mostly between 42-44 kmpl in city. Before, it used to fluctuate a lot, sometimes 38, 36, 40 like that.
I think Hunk's short gearing doesn't need it to be revved to hell, it can easily build speeds in top gear itself. Also, I avoid unnecessary downshift during overtaking.

Both chain covers got cracks near the nut holes, so removed them and riding without chain covers now. Need to get them welded.

The cylinder gasket is showing bit of leak it seems, I can see slight amount of oil near the gasket, also in the head gasket. I think I need to visit some ASC soon to fix them, also to adjust the tappets.

Since you mentioned about low pick up and heat, I suspect the clutch plates. What speed you get at say 5000 RPM in 5th gear?
Since you're in doubt about service history of the bike, take it to your local mechanic, change engine oil, clean air filter (If it looks very old/dirty replace them, costs around Rs.140 only). Also, ask him to check spark plug condition. Check chain slack - adjust chain and lube it properly.

Re: CBZ xtreme / Hunk

really a practical guide for selling ones bike. i did mind calculation suggested u ZMR

Re: CBZ xtreme / Hunk

For slow acceleration, first of all check the condition of your spark plugs and engine oil. If these two are in good condition, the problem might be a worn out clutch. Also you mentioned the bike hasn't been serviced in 3 months. Considering the previous owner did 54,000 kms in 4 years, that puts a monthly run of around 1100km. SO 3 months means almost 3500KM. Get it serviced ASAP

Re: CBZ xtreme / Hunk

Thanks for your input windrider, i was thinking of doing that, will do probably this weekend.
One more thing i asked, what would be the avg cost of servicing considering everything done, starting from cleaning to oiling.... in an authorized service center..

Re: CBZ xtreme / Hunk

At the authorised service center, you will have to pay around Rs 200 as fixed service charge. On top of that, an oil change will cost anywhere from Rs 250-300, spark plug change around Rs 110. So this comes to around Rs600 total. Doing this is so simple, you could do it yourself at home. If not, a local workshop is more than enough. Even after doing the plug and oil change you have trouble accelerating, then the problems might be with the clutch. When you put the bike in gear and start moving, does the rpm increase quickly with speed increasing slowly?? if yes, then its definitely the clutch. I don't know exactly how much it will cost to work on the clutch but expect it in the Rs 1500-2000 range if it needs to be replaced.

Re: CBZ xtreme / Hunk

New clutch plates cost 1300 rs approx + labour charges

Re: CBZ xtreme / Hunk

As for your bike hen let me be clear. The odo is showing 54 k so the bike is needing more than just servicing.

And one more thing is that if you want your bike to perform like new then stay away from SVC. find a good local mechanic. And there are lot of experienced member who can guide you and pay special attention to what they say. And last but not least pay special attention to me and what i say.

Extreme is the fastest air cooled 150 cc bikes. It accelerates like bat out of hell. If it is not accelerating properly then there ought to be a problem.

First of all i would like to add, that extreme feels the happiest when running on 10W 30 or 10 W 40 oil. 10 W 30 is best. If using 20 W 40 then let me tell you, extreme looses all the punch and pull and also mileage. So engine oil has to be 10 W30 and no other oils.

Second thing is tappets adjustments. Extreme is quite sensitive to Tappets adjustments. Since it has high lift camshaft so when tappets are not adjusted properly it will loose power heavily. Adjust inlet tappets at 0.06 mm for inlet and 0.10 mm for exhaust.

Third thing is clean and set carburettor. Extreme doesn't like running lean. So clean carburettor and choke thoroughly and set tuning. Most bikes tuning range from 7.75-2.0 turns from full closed position of fuel screw. Also check choke cable and replace that if jammed or has less free play.

Fourth thing is at 54 K the clutch will be worn. Change the plates to OE ones. Before changing remember to soak the plates in engine oil overnight before fitting it.

Fifth thing is that engine will be leaking compression. So best option is to re-bore the engine or new bore and change and polish the valves. Bike will run like new.

For shock absorber get it overhauled at shock repairing guys who repair gas shocks. Local mechanics can guide you to them.

And open the suspension and change the bush and bearings. Convert to twin bearings like i have mentioned few pages back.

And check the chain sprockets. If the previous owner had fitted Unicorn ones then your pick up will be screwed.

Man all the best!.

Nothing new for me. Moreover this is not an overhaul to see. Just boring and clutch plates change.

For me its like child play. So no worries.

As for the shocks got it repaired from a repairing guy who repairs gas struts and car shocks. He changes the oil, oil seals and also refilled Nitrogen gas in shocks.

Working better than new. Have jacked up the pre-load to third position from full soft which had made it stiffly sprung. Loving it as bike loves to corner. Just lean and it tips into corners.

Now no worries for shocks as that guy has said that he will repair shocks any time i want. Now i have two pair of shocks. One is on bike which i repaired and other is lying in home.

Cost was Rs. 320 per shocks along with change of mounting bush. Works better than new.

Yeah changing bikes after 3 years is waste of money, especially for a guy like me whose bike always remains new from inside and outside.

Moreover depreciation almost stops after 3 years so riding for 1-2 years after that is beneficial.

Moreover my bike has no problems. Just normal wear and tear.

Moreover i have got attached to the bike so thinking of selling now is making me upset.

And financially i have some big expenditure coming up so not eager to indulge in new bike.

But what to do as i am confused as i love the new ZMR. Each time i see on the street i feel very badly to get one.

Re: CBZ xtreme / Hunk

me too bro, the day i rode by friend's ZMR, iam tempted to buy it, but i will have to sell my Hunk then.

my bike has crossed 35000KM, i am planning to do the following

1. Fork oil change ( first time going to do. )
2. Chain sprocket along with sprocket bearing ( due to my ignorance in the initial period, it worn out faster)

apart from this i need your suggestion.

i feel like my engine sound has become little louder, dont know the reason.

for a 35000KM old bike, any parts replacement is required in engine like timing chain...?

what kind of maintenance is needed for rear shocks ?

and finally iam much interested in dual bearing setup, but sadly whenever i approach mechanics, they dont understand what iam asking... all they say, we have to dismantle to check for the setup.

My tyres are pretty solid and can go till 45000-50000Kms. so far no feel of skidding.
