re: CBZ xtreme / Hunk

CPR8-EA9 is the recommended plug. I believe Champion is the new recommended plug. But companies generally give NGK.

Change the Air Filter, 12k is enough km. :P

re: CBZ xtreme / Hunk

20w is more than enough, the dampening is good, just make sure the quantity is correct

re: CBZ xtreme / Hunk

No need to buy a carb for experiment. Even no need to buy a CDI for experiment. These were some suggestion. Next time just pull till 8k rpm in fourth and then shift to fifth. Mileage is very good and your carburettor is properly tuned. If you had been here or i there then i have lent you my bikes CDI to test. Although engine is same but these basic difference in firing and timing transforms feel and performance of both bikes.

Get the shocks re-serviced. You have mentioned that you have filled 175 ml which will cause less air and thus shock will hit and also while dis-assembly fill 160 ml and while draining and filling fill 155 ml. Also make sure to pump the shock 20-30 times after filing oil and before putting the fork cap. This ensures removal of air in shock. If air is not removed then shock will bottom out quickly.

Bike feeling heavy when heated indicates rich mixture. Change the air filter and spark plug. If the carb was tuned after cleaning carbon then after 1000 km retune it as the tuning that was done with no carbon will be rich when a thin layer of carbon sits on the head. IF tuning was not touched then just leave it and change the spark plug and air filter bike will feel like new.

Let me clarify a few things here. The real top speeds of various bikes are:-
Hunk- 113 kph
Extreme- 114-115 kph
Pulsar 150- 114 kph
Apache rtr 160- 118 kph
GS 150r- 113 kph
R15- 131 kph
CBR 150R- 132 kph.

These are some that i have collected from various magazines. As the engine gets free expect a 2-3 kph increase but not more. Hunk/extreme has accurate speedo which shows the correct speed and thus feels low. Other bike show 120+ which makes it feel like they are having high top speed. On this side of r15 and cbr hunk/extreme has one of the best top end pull as its powerband lies at high rpm. I always use the bike on highways and from my experience after 100 kph this bike still pulls like crazy to its top speed. The tuning is such that it pulls so quickly in top end that you wish for another gear as it hits the red-line. I have hit 117 kph although with crouching. I just get behind a high speed innova or scorpio keeping a distance of 60-70m and crouch such that my body is flat on tank and then twist and without wind resistance bike will simply climb revs like crazy. In winter season when the air is chill and there is no wind i find that bike pulls more eagerly to red-line. But mind that i do all this on the elevated expressway with barricades on both sides and also with helmet,jackets, gloves and shoes. That too for a maximum of 2-3 minutes so as to burn of the carbon from exhaust valve and silencer.My normal speed on highway is 80-85 kph and i always look at least 200-300m ahead. Also my habit is that i regularily scan the mirror for any fast moving car from rear.
So my advice is that do not always try to test the top speed just sometimes if condition is favorable then twist it to make the engine free.

I will update about my bike but damn your all queries are taking my time. Ok, nothing to worry as i will update in my next post as now i am going to office.

re: CBZ xtreme / Hunk

Thanks Sibun for your spot on assessment as always. Can you suggest any particular fork oil for xtreme as last time I used 'endurance' oil which is not performing up to the mark.

re: CBZ xtreme / Hunk

I'm on castrol and I find it up to the mark

re: CBZ xtreme / Hunk

You can try Veedol fork oil or Motul fork oil . If you want OE like damping then get Honda 10W grade of fork oil .

re: CBZ xtreme / Hunk

Thanks Sibun,

I am out of station now and will change my air filter, spark plug and Fork oil on my return(Boy I really do miss her).

Also, I always knew that my bike feels great after ripping her over 100, but now I know why. Thanks for the information mate.

updates on my extreme

It is the not the fork oil but overfilling and faulty workmanship that is to blame. Fill correct quantity of oil and flush air out of oil by pumping properly and it will work perfectly. Endurance is also a good brand, i have used in my joy and i forgot to drain and drained it at 25k and it was still running good without shock bottoming out and mind it my joy relies heavily on front shock as its front end is lower than splendor and passions and thus most load is on front shockers.

Ok, here is some update on my extreme.

Now my bike is running 100% on highways. On monday i ride it 172 kms to workplace and on saturday i ride it back to home, A round trip is usually 400km a week. Mileage has been a steady of 50-55 kpl with most of the time needle at 6k rpm or more.

Every journey has a story to tell.Last two mondays back i was riding to work place. After 40 kms a tavera overtook me. I was at 75 kph. I just followed the tavera to get wind protection but the tavera was not going above 80 kph and i was getting bored. On the back seat(side facing seat) there was a kid and two hot chicks. I was fully kitted up with helmet, gloves and jackets. Initially the chicks were looking towards front and not looking at me. It was also cloudy. The kid at the back waved at me, and i waved back. Sometimes i would overtake and sometimes the tavera, this went on for some 40 km, and finally the chicks had a look, i just gave a smile and we hit the elevated expressway near balugaon, here the tavera slowed to give way for an oncoming traffic and i just downshifted and crossed the tavera and went away.

The previous week i.e 7-13 i had to come home thrice as it was rath yatra and our new home puja was there. So i went to work place on monday returned on tuesday night, again went on friday and returned on saturday as saturday is half day. So last week a total of 1200 km was clocked which comes up to about average of 200 km a day if you consider six days as on sunday bike rested as i was riding my joy. Also bike rested on wednesday and thursday as i was riding my joy.

This Monday:-This monday i was returning from Home when i happened to meet a volvo bus. Let me get into some background. Two volvos are now running from hyderabad and bhubaneswar daily. Usually when i return from sunday one passes me in opposite direction opposite and on mondays same thing i meet one in opposite direction.Now this bus are Volvo 9400 xl- multi axle coach. Some of its specification are 340 hp at only 1900 rpm and earth revolving 1600 Nm @ 1100-1500 rpm. While company recommends a maximum speed of 100 kph but this behemoth repeatedly touches 120-130 kph due to its sheer torque as it crosses its maximum rpm of 2200 rpm easily.So this Monday one approached me from behind and i gave way. Then i decided to follow it(with no intention to overtake as i want to see how fast these behemoth goes), and i was surprised as when i touched 110 kph it was still pulling away. And when it slowed, it just pulled away so rapidly due to its humongous torque of 1600 nm that too at barely 1100 rpm. So you see torque does what horsepower cannot do, the volvos pulls their weight so effortlessly and so quick that it is a pleasure to watch.

On another note i am thinking of trying ZEN filter modification on my extreme as PSR sir has done on his karizma. Also since my running is heavy, filter gets dirty in no time, and also since extreme carb is large at 28 mm it will benefit with better breathing as low end pull will improve, which is the only sore point in extreme as it has very little low end torque. I will ask my mechanic to try with the cutting as i have no cutter and he has a excellent knife which just cuts plastic like hot knife in butter. Stay tuned for this mod updates.

Well, I thought it might be P375, but by the looks of the silencer its definitely a hero.. But again n gain the tyre is small. .may be its 110/90

Re: updates on my extreme

Hi All,

Does oil change improve performance of bike. What is the best engine oil(easily available in Bangalore) for Hunk(has run 24K KM's) provided service interval is 2500-3000KM's. Changed the oil last time at the Hero service centre and just after 1200KM's , feel the pick up has gone a little bad.


What is the change interval for Castrol Power1 Racing and Castrol Activ Xtra 20W-50.

Re: updates on my extreme

Yes it does , and nothing feels as good as fresh oil in your engine . That is a feature of the Hero 10w30 oil , I usually drain it around 1500 kms of use . 20w50 is not the right grade oil to use in your hunk , whatever the brand .

re: CBZ xtreme / Hunk

If u want drain interval above 3000-3500 km you should use synthetic or semi synthetic oil
15w40 or 10w40
Dont go for any 20w50 it can eat your pick up

Re: updates on my extreme

I'll surely take care of this.
Meanwhile, I'm going to get my xtreme serviced tomorrow evening, as it has clocked 2200 Kms on current engine oil(Shell Advance AX7 SS). This time I'm going to use Gulf Pride 4T Plus 10W-30 (Only Rs. 200/- for 900 ml of SS oil ) and I've also purchased NGK G power-CPR-8EA-GP9 Platinum tip spark plug. Let's see how they perform.

re: CBZ xtreme / Hunk

Thanks for the response. Can you suggest some easily available Synthetic or semi synthetic oil. What about Castrol Power1 Racing (10W50), is it a fully synthetic or semi synthetic oil?
