You said that you managed to get 112 km/hr with pillion.

Members plz reply..only i am the one who got this speed or everyone getting same.

I remembering hitting 108kmph odd in the early days of the bike with a combined weight of around 120kg perhaps. 100kmph is quite low and the bike is definitely capable of going faster.

Thanks for your reply. I initially had a 180cc bore from joel which seized and then broke free on the highway scoring the cylinder walls. After that Joel put in a 170cc one (that is what he told me). So I think even for same engine block you can indeed have different bore size. That said I have absolutely zero idea on how to verify the claim short of opening the engine and measuring the dimensions with a vernier caliper (which I am not going to do).

My previous jet (115) was pretty lean with a solid flat spot at 6000 rpms. The 125 jet from Karizma seems to have solved that problem though.

If you are not finding any flat spots and if the engine is pulling clean on WOT then I think you are good to go anyway. In case you need bigger jet then Hero Impulse jet is size 132 and you can order it from Hero Central Spares Distribution Center at Kasturba Road (Parshawa Motors).

You are getting fantastic mileage, I get about 42-43 which is the same as I got before getting big bore. But highway ripping kills the mileage completely, I end up getting 34-35 kmpl with constant cruising at 95 kmph.

Any way thanks for the reply!

Did you get the 170cc bore on warranty? How has the current bore served you?

Maybe you can try the Main Jet of the Xtreme/Hunk. :P My big bore is really efficient with the stock Main Jet.

And thank you for the information about the Impulse Jet! I had no idea there was a compatible jet with a size above 128!

42-43? I got the same mileage earlier too. But a tappet adjustment and a carb tune sent the mileage shooting by almost 25%!

PS: Parshawa Motors is somewhere near KH Road, right?

I don't remember seeing it near Kasturba Road. :P

Also, could you check if these jets will fit the Hunk? They look different. But apparently, they fit.

but I have to keep in mind that tyres were stock and almost 3 years old with 15K on the ODO. would be great if owners could post how much lean is possible and what tyres and changes were made to get the max out of the ride.

I have always love cornering on the Hunk. I have never bothered to check the lean angle, but I do remember the exhilarating feeling I used to get.

I had once taken a left turn at speeds of around 65kmph I think. I don't try such things anymore though.

And somehow, I am more comfortable cornering into left turns than right turns. :P

Remember reading in an old review of Xtreme in a major auto magazine that it handled like a sports bike.
AFAIK, Hunk shares the same chassis of Xtreme, so shouldn't be bad.
May be the stock tires are the culprit.
Between, in which track did you ride your bike?

I never felt that bike doesn't handle well, BUT after looking at the pics taken at the track I found that lean angle is no where near as expected! and I rode it at MMSC race track chennai long back

Afaik, no one has calculated the lean angle in Hunk. but it cannot do much of cornering like R15 due to obvious reason. it has got less rigid frame (the school boy - single cradle). but upsizing the rear tyre would help but aspect ration must be very low. otherwise there is no use in upsizing the tyre. max 120 section can be accommodated. also you can set the rear suspension to stiffer setting which you will feel much more in control but your back will hurt like hell in bad roads.

Though in corners it may not be an expert, but it requires shorter turning radius which helps a lot in city ride.

since you have gone to track, i hope you are familiar with some of the basic cornering techniques as well.

I did tune the suspension to stiffest possible setting, I guess problem is with the frame. I am quiet familiar with counter steering and other stuff like throttle control when cornering.

Even I felt very comfortable while cornering, but only after looking at the pics I felt that it's no where close to what I expected, I took the first corner(not a sharp one) at 90+ km/hr. Guess race tracks demand a lot from the ride.

re: CBZ xtreme / Hunk

So I did everything as Sibun said,the bike now runs like a dream but mileage is still a nightmare at 35. What the hell is wrong with my bike?

Oh and the bloody plug still shows lean.

one thing i would like to add. for me while cornering, looking in the direction of turn (turning my head towards the direction of turn ) helped me a lot to lean more with little more speed.
also bracing the outer thigh to the tank and then opening the inner thigh little bit boosts my confidence.

may be iam not obeying the rules, but this helped me a lot.

besides nothing to worry about handling in Hunk/CBZ since these are not made for that.

it is the Handling Vs Comfort curve where are both mutually exclusive.

Digital tachos somehow don't feel right.

That would be me, PRATHM.

Tacho on both extreme/ hunk is digital especially after 2011. Only the face is analog else everything is digital as it runs on stepper motor. only the looks are digital. Analogue tacho are those that runs on cable like RXZ, or those that runs on galvanometer like caliber.

Hi,

I have a claimed 165cc bore.

And as for the jetting, the Hunk has a stock Main Jet size of 128. :P

I have been unable to find any bigger jets. And if at all, I'll have to order them from jetsrus where the cost of shipping is more than the jet itself! :/

Anyway, as for the big bore. What kind of details do you need?

I don't feel any flat spots as such. The bike pulls neatly enough. Though a solo top speed run is still due. The mileage is terrific, around 50kmpl in Bangalore city conditions. I currently use a 15T front sprocket from the Unicorn to better utilize the additional torque I got from the big bore.

That said, is there any real way to verify the CC or the bores we have? Considering the Dazzler and the Hunk run similar engines, hard to imagine Joel would have different sized ones for different bikes with similar engines.

Also, after cleaning up the Slow Jet, the bike behaves exactly as expected.

No random shut off and idling problems.

Aall izz well in Hero Honda Hunk land! :P

Bore size can be confirmed just by opening the head and checking with vernier calliper for the stroke of piston and the width of bore by dial guage. Stroke length will be same as stock, so measuring only the bore diameter will suffice. Use the formula for cylinder i.e V= 3014*r^2*h. Here r- dia of bore/2 and h= stroke of the piston.

I have some questions on big bore which i will ask on Pm.

If you are ridding in city, then most probably the tyre would have flattened a little on the center which would have decreased the lean angle. Extreme/hunk has one of the most well sorted out suspension and chassis which makes it lean amazingly. But the tyre should be round in structure. No the stock tyres are good except that it must be right shape.

Moreover cornering is an art which with practice you can master and lean more and more. Extreme will corner better than hunk because extreme has rear set footpegs and sitting position is little racing position.

Remember four things while cornering(for new riders),
1. Sitting position should be perfect for giving weight on handle bars i.e sitting position should be such that your chin is approximately near the tank cap.
2. While cornering the outer thigh should be bracing the tank, and the inner thigh should be inside the curve, with knee pointing towards the center of curve.
3. Move your ass, rather than sitting on seat you should move your ass. You must hang down from the bike towards the inside of the corner and be prepared to move up when bike is straightening. while you are moving from right to left move your ass with your legs.
4. Enter the turn wide with looking over the apex, and gun it while exiting the corner.

Ya very well, it is very good to buy the new extreme as it is most powerful in 150 cc on this side of air cooled bikes and also gives pretty good mileage. Handling is more than a pretty average joe can use. Buy it and you will never regret, however if you have no hurry, wait for the extreme sports.

Get your tuning set properly, as with this tuning, your bike will be struggling to build revs or pull hard. Get it tuned from a good mechanic or tun it from ASC by using inductive tachometer.
[MENTION=39287]dineshaugustin[/MENTION]- Can you upload a video of the sound you are telling.

Looking at the extreme then here is a picture of its cornering ability:-

Yes i have a lots of issue of OD mag and i have kept all issue in safe like in museum, for which i have to hear earfuls from mom. I have the test ride of extreme and 24hr run of extreme which i am going to post on the day when my odo will tick 40k. Will post a buying experience, ownership experience and hell lots of photos.

This was one of the photo but i had to post here earlier.

Look at the photo carefully and mark what i have said, Direction of knee. placement of chin, ass hanging from seat, looking at the apex, position of toes, and the position of elbows n 90 degrees.

When i was a novice i studied this pictures and practice this on my joy and i scraped the knee pads in 2 days on my joy.

Yes, you are doing it right, we should always look at the direction of the corner rather than looking ahead.

One small correction, Hunk does have similar seating position to CBZ, I got similar lean angle to what is shown in the pic, only difference is that I didn't hang out that much. Tyres are also a reason as you said

even with such little lean angle the front tyre didn't have any chicken stripes, which means that is the most I can get out of it.

Wooow. never seen this lean on Xtreme. Really practice makes difference.
Between any dual compound tyre is available for our bike.? eventhough we lean, we cannot avoid chicken strip since our is a single hard compound.

Even if you get more leaning angle, the speed would be another factor. say if Xtreme/Hunk can do a turn at 40kmph, then with the same lean angle R15 can do 50 or so and also the counter steering is better. this is due to the fact mono suspension, chassis and mass centralisation and low COG.

There are multiple reasons why R15 would be better than hunk as you said, only reason for my query is that I want to take my bike to it's limits before upgrading to a bigger bike. I wont sell my Hunk anyway

I am extremely attached to it as it is my first bike.

then fitting broader tyre with low aspect ratio will definitely help

If by warranty you mean without paying any extra money - then that's a yes. Have done a shade above 20000 kms on the 170cc bore including all sorts of ripping on the highway. However I have not yet tested top speed ever and I have never run the bike on WOT for more than 5 secs ever. Still scared of a bore failure so I never do these things. However the bike can cruise at 100 for extended periods of time without a problem. Acceleration upto 110 kmph is also effortless and easy. Though like I said, cruising at over 95 kmph brings down the mileage to 35 kmpl.

Maybe you can try the Main Jet of the Xtreme/Hunk. :P My big bore is really efficient with the stock Main Jet.

Well I did try looking for Hunk main jet but could not find it anywhere. But for the moment I am happy with Karizma's jet if 125 so no worries on that front.

And thank you for the information about the Impulse Jet! I had no idea there was a compatible jet with a size above 128!

No worries!

42-43? I got the same mileage earlier too. But a tappet adjustment and a carb tune sent the mileage shooting by almost 25%!

I also got my cylinder head ported from Joel and after that the tappets always get loose within 2000 kms of riding. Within that time also i do not see any mileage improvement. My carb is also tuned properly now so the reason for low mileage is something else. Any way I am not that bothered. 42-43 is good enough for me.

PS: Parshawa Motors is somewhere near KH Road, right?

I don't remember seeing it near Kasturba Road. :P

To be honest I am not too sure about this but Parshawa Motors has a separate building located I think on Kasturba Road which is just a spares distribution center, not a showroom. But I may be completely wrong since I have never been there.

Also, could you check if these jets will fit the Hunk? They look different. But apparently, they fit.

#130 #132 #135 #138 M5x0.8 Main JET For Mikuni KEIHIN Dellorto OKO KOSO PWK GY6 Carburetor ATV Buggy Scooter Dirt Bike Parts -in ATV Parts & Accessories from Automobiles & Motorcycles on Aliexpress.com | Alibaba Group

The length measurement for our jets (keihin VM28 carb) is 7mm and the website is saying for these jets as 8mm. So I can't say for sure if it will fit. Check the measurements against the ones given in jetsrus. The following is the link:

Keihin round main jet 99101-116

This is the jet which fits out carb.

Zapper Q is a good tyre for cornering. but to get most out of tyre it should be low profile. but for our bike it is not possible to very low profile.

as far as front is concerned, stock is better since other tyres are not suitable for our bike.....damn 18"..!!

hey bhpians
From past few days there is some continuous sound that comes from inside my xtremes fuel tank only when the fuel is low.
I think the sound is coming from the fuel gauge.
What should i do . please suggest. I referred this to a local mechanic but he says that the fuel tank cannot be opened

what kind of sound.? when it occurs...?? during idle, acceleration..??
