Here is the spark plug pic of my xtremeDo comment on mixture setting

re: CBZ xtreme / Hunk

I had varying idle issue when AFR setting was lean, also my spark plug was too old that time.
Tuned the bike myself, changed spark plug - I haven't faced then problem since then.

ASC usually messes up with disc brakes. I had the same issue with my front disc after ASC changed the disc fluid. Had to get the issue resolved in a local workshop. He cleaned the tube and changed master cylinder piston. Its almost a year after that, no issues so far.

re: CBZ xtreme / Hunk

Looks a little lean to me!

The carb hasn't been cleaned in more than 10,000km and speaking of Spark Plugs, my spark plug has brown spots, not the ones you get with a good mixture, but spots like it has been burnt at those places. Can fixing these 2 things solve my problems?

But I don't understand why the bike shuts off at very, very light throttle input?

The brakes, I've never been happy with the front brakes. The new bikes have Bybre brakes. To get brake bite like that, must I change the entire brake setup except for the disk or only the master cylinder? Or will changing the major and/or minor kit do the job? I've already switched to the KBX brake pads in front, but not much help.

For those reading this post, this is the link to my original problem:

re: CBZ xtreme / Hunk

@ashwin.terminator Try changing the spark plug and retuning the carb as satson said. Also varying rpm shows either you are running lean or there is air leakage into carb . A lean mix causes problematic issues of hot starting and a fouled spark plug adds to it too.

EDIT : Added a pic of my plug earlier one wasnt much clear .. Please comment

re: CBZ xtreme / Hunk

Man, from engineer you converted me to a doctor, speak all you can i am all ears.
Regarding achiever then let me tell you some of the positives of it:-
1. First of all it is the most fuel efficient 150 cc bikes around. My friend has it and most of the time mileage hovers around 60 kpl.
2. The seat is the best as it is very comfortable and if you are married then your wife will be thankful as its rear seat is most comfortable.
3. The bike is light at 134 kg so will feel lighter to zip through traffic than hunk and CBZ.
4. Maximum torque is at 5000 rpm, so pull is better than even UNICORN in low revs, almost pulls like splendor at low revs.
5. The new model looks quite good and has alloys with all black theme, and has also Disc brakes. Also the headlight shape is so good that high beam pattern is excellent as noticed in my friends achiever.
6. Is as quick as Unicorn to 60 kph and slightly more quicker to 80 kph than unicorn although not as quick as extreme, although not significant difference.

I have given you some positives and if you are interested then let me know i will tell you the ride experience and all. And regarding popularity then let me tell you i do not see what is popular or not, i see the product and buy. When i bought the Joy then passion and splendor were hot sellers and even Joy flopped, But any one day i have not regretted the decision, instead i feel happy and one of my old friend is there who always say that we both have so much memories with this bike that i love this bike as much as you do. Evan after 12 years it still returns 75-78 kpl in city and with two up it pulls inclines better than my extreme at low speeds in high gear. So i will not advice you whether to go for it or not, but see what you feel and let me know.

Clean the carburettor and change the air filter, extreme/hunk have 28 mm carburettor so it is very susceptible to dirty filter. I have faced the problem and changing the filter solved it. Also re-tune the carb after all this.
For the front disc get a new major kit and completely overhaul the master cylinder bike will be back to original bite. If you want you can change to BYBRE master cylinder for more braking power or can change to KARIZMA master cylinder kit.
Regarding rear DISC then those idiots while fitting has made the pads greasy or oily, check it and change it.

And regarding those ASC it will be better if you never go to them, find a good independent mechanic, or better work on your bike. I am here to help you all, and to remove your dependance on mechanic, and i assure you i will help you solve all your problems, even you can call me anytime, ask SHOEB and PAUL they have called me anytime and i have helped them, even PAUL re-built an engine by calling me and taking guidance, So i urge you to learn everything and no need to worry, I AM HERE HAVE NO FEAR. Post any problem and i will help. Even once HONDACBF had called me regarding his bike leaking oil and i had helped him and his problem has gone for ever.

I HAVE SEEN THAT YOU HAVE GONE FOR BIG BORE KIT FROM JOEL AND ALSO HEAD WORK, SO CAN YOU LET US KNOW YOUR EXPERIENCE AND ALL. ALSO ANY DOUBT ASK ME.


Spark plug is alright do not fiddle with tuning more.

Reagrding servicing then two weeks back i did the first servicing of my extreme on my own, i will post the details in another post(previous all service was done in service centers).

re: CBZ xtreme / Hunk

I too noticed that when I was going through team-bhp.
[MENTION=20978]ashwin[/MENTION].terminator
You get all help from here but don't update anything here. This is not justified,not at all.

re: CBZ xtreme / Hunk

Where's the Like / Rep button ? MOD's pls take care. You deserve this dude. I'm going thru all posts again to know more abt bike parts and how to detect issues or tune so that it bring smile everytime i wrist the throttle.

re: CBZ xtreme / Hunk

Thanks for those words of encouragement Sibun. It certainly gives me the confidence to tinker around on my own. I did call you once and your diagnosis was spot on! Just that, I tried cleaning the carb once, couldn't figure out what to do with the TPS. Then I forget to tighten a screw that led from the carb to the head and I'd lost the idling screw's spring. So I'm a little scared of I'll end up doing again. Also, my spark plug seems to have burn marks on the sides, must I change my plug or can I continue with this?

Haha, looks like my post on Team-BHP hasn't gone unnoticed. Well, yes, I will do as you said. My bike's carb hasn't been cleaned in 10,000km. So I'm almost certain it's all clogged up.

The brakes yes, is the Bybre better or Karizma's? Karizma's is Nissin, yes? I was never happy with the stock braking, so will a change in Major Kit really help? And any idea how much the Major Kit should cost?

And the Big Bore well, I haven't really been able to use it to its full potential. The pick up increased dramatically, as you must've read, only once had I touched 102kmph on a flyover here and once the big bore upgrade was done, 108kmph was consistent. I could go faster, but had to slow down. Bike would redline very, very easily. Lots more grunt, but coupled with the short gearing, it meant I would only be accelerating faster while my ultimate goal was to cruise easier at higher speeds.

But now, after the sprocketing, I could pull away from a P200NS in 3rd and 4th gear. The bike is stonking fast in 3rd and 4th, amazing fun. Fifth gear is quite lazy for now. I expect the bike to be capable of 120kmph now.

According to Joel's numbers, my bike should currently be at 17.xx bhp.

Mine is a very vague review of the Big Bore, I will update thoroughly once I go out on a long ride this June.

Sibun, is it possible for you to actually give us a DIY on how to service our bikes ourselves? From what all is to be done to how it is to be done.
Someday, when you're servicing your bike, could you take pictures of what you're doing and then put it up with text in the form of a tutorial? It'll benefit most of us here I am sure. I for one am a little skeptical to working on my own bike because Sunday is the only day I get to work on the bike and if something goes wrong, getting to college on Monday is going to be a big pain. If we had a reference, we can only go wrong in minor places and can keep required tools in hand along with necessary spares.

Haha, chill my man. I wanted to get all issues sorted before I post here, the mileage being the biggest one. I didn't want Joel to get any flak from this community which knows him so much better compared to Team-BHP. I wanted to post once all the issues not pertaining to the bore were sorted out.

It's not a valid reason perhaps, but Joel did a brilliant job with the bore and I didn't want things like a clogged air filter, dirty carb, damaged spark plug bring him any disrepute.

On a side note, I cannot wait for Joel's High Lift cams. I don't want any mods to be visible on the outside, like a FFE and what not. The exterior should be the same, but the inside should be a different story altogether.

Also, I was wondering if the new Xtreme's footrests will be a direct fit on the Hunk? From what I've noticed, the spring in thr Xtreme's footrests don't settle into a hole. Rather, they settle on the outside of the footrest itself. So by my estimation, it ought to be a direct fit. Anyone has a better idea about this?

re: CBZ xtreme / Hunk

Yes Sibun most of the above points are felt during my Test ride. The gear shifts are bit stiff when compared to my Unicorn. Maximun load specified for Aciever is 130 kg, the same for Unicorn is 170 kgs so what is the difference here. Is the Achiever is too light to take more weight. Aiso can you comment on new Achiever's Head light brightness.
Is your friend's achiever is latest model?

Re: brakes and oil queries

Hi Sibun,
I've visited two different authorized spare parts dealers, but mentioned parts were not available. Instead they were having complete rear master cylinder kit costing 2600.00 which I cant afford.
Can I find the minor kit in local market which are made by other manufacturers. I reside in Delhi and karol bagh is hub for spare parts. Plz suggest.

Re: brakes and oil queries

IMO I am afraid will I get the front disc parts as suggested by sibun, they looks like similar to yours here they are:-

The part number are:-1. 45503-KCC-841- PISTON 2. 45504-KCC-841- BOOT COMP3. 45506-KCC-841- SPRING4. 45525-KCC-841- PUSH ROD5.45526-KCC-841- SPRING , PUSH RODThese all are included in the kit or you can buy individually in this part number.Or if you want complete master cylinder the part number is 45510-KVN-901 M/C SUB ASSY, FR. BRK

I also reside in west Delhi, In which SVC you have visited, can you let me know because I also have to done my front disc work this week, Usually I visit to Rama Road SVC, Otherwise I will have to buy complete master cylinder kit...

Re: brakes and oil queries

Hi itsmevini123,
I've visited karol bagh SVC as well as patparganj SVC. It seems to me that these SVC's are only intrested in looting the customers rather than helping

Re: brakes and oil queries

[MENTION=20978]ashwin[/MENTION] and Nitesh

These parts are usually not sold by the SVC over the counter for some reason. Try to get them from reputed spare parts shop and make sure these parts are genuine.

Re: brakes and oil queries

Thanks for the tip man. Will it be available at Hero's authorized stockists? There's one called Parshawa Motors here in Bangalore. Service centers buy their spares from here. They ought to have it right?

Re: brakes and oil queries

It will be available with them for sure but these stockist don't bother selling small items in small numbers to individuals. Try to go there when they are less busy.
Print that particular page from the parts catalog and carry it along with you.
