re: CBZ xtreme / Hunk

Today I tried to tune my afr as per Sibun's guide. I did everything as told,set the screw at 1.5 turns out,removed the pipe and all but as I started tuning, my rpm was barely increasing. Any ideas why?

re: CBZ xtreme / Hunk

Did you warm up the engine before tuning? Cleaned air filter?

re: CBZ xtreme / Hunk

Air filter was cleaned a week ago. And I went for a ride before trying it. I set my rpm to 2000 when I started tuning and did not see gradual increase in rpm. The needle was rarely constant and the highest I got was 2500 rpm but it was not constant either.

re: CBZ xtreme / Hunk

Ok then, rpm will increase very slowly that is not an issue hear to the engine sound and note the position where rpm is maximum. Stop at that point. In my case rpm was increased to 3.7k maximum and got a tuning of 1.85 turns. If things are not going good then check for air leakage from carb and air hose pipes.

Set your rpm to 3000 before starting

re: CBZ xtreme / Hunk

Will do that now. Thanks. Do you think low acceleration is because of afr problems?

re: CBZ xtreme / Hunk

Cannot finalize it because of afr problem.. Afr problem will create vibrations,less power, low fe,hard gear shifts and also low acceleration, misfiring etc

re: CBZ xtreme / Hunk

So I dit it again and acceleration is much smoother I can now go at a decent pace at third gear and keep it below 4k rpm. Thanks for your help. By the way,which gear and what rpm range is best for city riding?

re: CBZ xtreme / Hunk

There is no text book for riding and gear shifting.. Just ride according to the conditions. But make sure to take care of your bike..

re: CBZ xtreme / Hunk

Hi Friends,
My xtreme has clocked 40,000 Kms till now.
Visor was vibrating a lot and was producing weird sound. Also I was not satisfied with the performance of Makino Front disc pads.
So, today morning I went to my mechanic to sort out these niggles.


1. Visor: There are two rubber grommets fixed at the two ends of the visor. Both of them were not looking in good shape, so they were replaced. Now the vibration issue has certainly reduced but still it vibrates a bit @ lower gears

2. Front Disc: I had replaced the front disc pads with Makino ones around 2 months back. But of late, braking performance was not satisfactory. Also, it was constantly rubbing the disc plate even after filing it with sandpaper, due to which there was screeching sound coming which was very irritating.
Luckily I found a Bosch Retailer and purchased Bosch Front disc pads. Now, the braking a has improved and bite is back. I observed that the thickness of pad was less in Bosch pads as compared to Makino pads, so they are not rubbing the disc plates as well. While installing, my mechanic just filed it slightly and that was enough.

3. Engine oil: My xtreme was running on Hero 4T Plus 10w30 engine oil since last 1500 Kms. Performance of this oil was quite good for the initial 1000 Kms, but after that I felt a dip in performance, may be because of the heat of Delhi. So, reverted back to my favorite Gulf Pride 4T Synth 10w30. But I must admit that my bike's engine was revving nicely on Hero oil.

Below are some images for reference.

I removed the TPS sensor above shown in red circle.<br />
Is it functional normally or required some calibrations. <br />
If yes .then what would be procedure for it.<br/>

re: CBZ xtreme / Hunk

If you disconnected it, there isn't any problem. But if you unscrewed it and removed it altogether, you will need to recalilbrate it.

I don't remember the procedure, @sibun had posted it somewhere earlier.

You can thank sibun.
As for my bike, I did carb tuning and tappet adjustment today as I found my bike to act as if it was short on fuel at speeds of around 70 kmph. Will know the result of my changes tomorrow. *fingers crossed*

Special thanks to sibun who helped me through the procedure.

As the bike sounds now, it sounds better than it did before. I'm not sure if that is a placebo effect of it is the real deal.

Either way, bated breath till tomorrow morning!

I was browsing through AliExpress and found this to be quite interesting:



Front and rear disk pads for Rs. 1260 odd. Any idea if they will fit? Curious to try them :P

re: CBZ xtreme / Hunk

My Hunk's headlight isn't responding to the switches. It is stuck in high beam. I cant get it on low beam or turn it off without shutting off the engine. Any help please. The bike was in a rain shower today is that the reason for this?

re: CBZ xtreme / Hunk

Is it available in tubeless...?.most imp did u do any modification for accommodating 110 section.?

re: CBZ xtreme / Hunk

No its not available in tubeless, but now the days most of the tube tyre are same as tube less so its upto you to use the tube or fit the tyre directly on your rim, I think your bike rim must be compatible with tubeless tyre if its not one can not use tubeless tyre.

No modification required for 110 section, you can fit it without any hassle and yes to avoid any problem I have bought a bottle of liquid to avoid/minimize tyre to deflate in case of any puncture and poured it in the tyre from air filling hose...
