Hunk Mileage problem

I have a Hunk dual disk with kick start. It is 3k old on odo. The bike's mileage started increasing till it reached 40 and now it is again going down the last check revealed mileage to be 35. I adjusted the tappets and found a leaking wire and repaired it. The rpm immediately shot up and after adjusting it,I thought that the mileage problem was resolved but it still persists. Also no matter how many times the afr is tuned, the spark plug always suggests a lean mixture. I don't rip the bike either and accelerate gradually and smoothly.


Gear Change pattern :1st at 3500-4k rpm and rest at 3k.
Air filter cleaned,oil changed less than 3 weeks ago
Proper clutch freeplay is there.
At 5th Gear and 4000 rpm speed is between 48-to 50 kmph.

Re: Hunk Mileage problem

Leaking wire ? from where ? A leaking wire or pipe ? but it wont have this much effect on mileage . What do you mean my rpm shot up ? Tell in detail or pics what steps you followed . Are you tuning according to sibun's method ? It is the only method for perfect tune , i did the same and you can follow that on my signature for pics or details , After setting tappets , oil change mileage was upto 55+ , Lowest i got is 46 due to rip on highways .

Rest all is good , speed-gear-rpm is correct so no clutch issues. Mileage is something which depends upon two things
1. Man
2. Machine

When i drive my cbz xtreme is usually get 50+ kmpl , if someone else drives it it falls to 45 , reason lies in throttle control . You need to learn how much throttle will give corresponding rpm , by opening that amount of throttle wastage is reduced . So i learnt from [MENTION=14414]shoeb[/MENTION].2015 that we can cruise at 70-75 just at 1/5th of throttle , which gives us superb mileage considering its a aggressive mapped and heavy bike.

Re: Hunk Mileage problem

can you please post the link for throttle control.?

thanks.

Re: Hunk Mileage problem

I meant a leaking pipe. After repairing the leak the rpm automatically increased from 1000 to 1600. And yes I do use Sibun's method. I have a printed copy of page 697. I don't know what the problem is but my mileage is frustrating me enough that I am contemplating selling it and buying an FZ especially now that my bikes mileage is worse than it. I also control the throttle as much as possible and rarely move my hands. I just start and give a little bit of throttle and hold it there till I reach the desired rpm.

Re: Hunk Mileage problem

I was considering getting myself Riding Gloves with my first salary.

I came across this:
2014 High Quality Brand New Alpine/Stars GP PRO Original MEN'S Leather Motorcycle Racing Gloves 7 Colors Free Shipping-in Gloves from Automobiles & Motorcycles on Aliexpress.com

Any idea how genuine this is? Sites everywhere are retailing this for Rs. 14,000+ and these guys are charging Rs. 3000! :O What's the catch(if any!)?

re: CBZ xtreme / Hunk

[MENTION=40365]ashwin.terminator[/MENTION].. Price gap this huge, the product can't be genuine.
Get Rynox Rampage. There were my first gloves also. Best for city use.

Re: Hunk Mileage problem

Which pipe was leaking. Can u pls post the pics showing that pipe.

Re: Hunk Mileage problem

Next time I remove the tank,I will post a pic of the pipe.

Re: Hunk Mileage problem

Price difference is huge, though Chinese can do anything take it as a bet....Let us know if you order, we also would like to get them...

Re: Hunk Mileage problem

I am also getting around 40 kmpl only in my Hunk in city rides.
But my bike is running only in city. (Still it is a bit low, I know )

Please let us know the following, so members would be able to guide you better.

How many kilometers on Odo?
How do you check mileage - Reserve to Reserve method?
What was the mileage you used to get before?
Any major change done recently?

Re: Hunk Mileage problem

3k on odo.
Reserve to reserve.
Mileage for brand new was 26,gradually increased to 40 the dropped to 35.
No major changes. It dropped automatically.

re: CBZ xtreme / Hunk

Your bike's AFR mixture is perfectly alright . You can lean it out a wee bit ( or not ) , since you seem to be riding a lot in low rpms ( traffic ? ) .

re: CBZ xtreme / Hunk

An upgrade that I have been longing for so long finally came to fruition around 30 hours ago.



Finally upgraded the brakes!

My quest for better brakes began just a few days after I bought the bike. After the euphoria of a new bike died down, the reality check was that the stock brakes were way too spongy. Tried changing pads, fluid, but nothing really helped.

Ray of hope was @SunnyBoi, who suggested a hose + caliper change as he had done on his Karizma. I toyed around with the idea a little bit. Sunny suggested a Pulsar Master Cylinder with the P220 brake hose, as he had done on his ZMA. But I had experience with the old Pulsar brake, the ones from ETS, they were supremely sharp. But I hated them. Why? You could never modulate them. They were, as Sunny put it, the "on" and "off" variety.

I had always appreciated the brakes of the Yamahas. So I went about enquiring about the costs of the Master Cylinders for the 2 main contenders. The FZ and the R15. After hearing the costs, it was an easy decision. Rs. 1200 vs Rs. 4000.

This Monday, I'd gone to Khivraj Bajaj, Kasturba Road and bought the Pulsar 220 Steel Brake Hose. Then on Tuesday(Yesterday), bought the FZ Master Cylinder, which didn't have the lever attached to it nor the brake light switch. Bought the other 2 separately along with the Banjo Bolt from Perfect Riders, Lalbagh Road, Bangalore.


Post which, I headed straight for Sunny's place. He had offered to help me make the swap. And to be fair, I didn't help. He did all the work himself and also made sure it was a thorough job.

I tip my hat to you, @SunnyBoi "Saar"!

He first drained the old DOT3 fluid and flushed it with DOT4 fluid with the old Master Cylinder itself. Then we proceeded to removing the old Master Cylinder and the Brake hose and replaced them with the new ones. Fairly straightforward.

Problems faced were not too many. But one main concern was the length of the hose. It just fits. And you can't route it through the inside of the headlamp assembly. It had to be done from the outside, by the side of the right forks. But not really a concern. This is why I needed a zip-tie. To secure the hose. Also, the FZ Master Cylinder didn't come with the Master Cylinder Kit(or atleast part of it). The assembly did not have the rubber cup like thing, the pushrod and the spring that connects the Lever to the Master Cylinder. Luckily, the ones from the stock Master Cylinder were a direct fit! So that was another another minor headache averted.

Also, the brake light switch of the FZ uses the same kind of connector clips, but they were complicated. The switch was connected to a pin that would end right after the Master Cylinder and there was a extension cable with make clips inside a plastic connector, which wouldn't be able to house the stock brake light switch clips. Removing the extension cable was an option, but the stock wires were too short to reach the clips directly. So Sunny did a stop-gap arrangement to ride away in safety for the day.

The moment of truth was the ride I took soon after. I didn't feel very happy at first, but a few 100m into the ride and a big smile was plastered across my face. The brakes were beautiful. Super sharp! And the feedback was outstanding. I knew exactly when the tyres were going to lock.

Come next day, I wanted to get the brake light switch connections fixed. The exposed wiring stuck out like a sore thumb. I felt that the best option would be to cut short the extension cable and then fit compatible connector clips to the end. I went to Gowri Automobiles, RV Road, Bangalore and asked them for "Horn Connector Clips", just as @shoeb2015 had told me to. The gave the clips. But there was a problem, they were too big. Searched JC Road, SP Road, but didn't get the right size.

Came home and cut the clips using a plier. After some trial and error, got the size right and made the fit. So everything is perfect now!

This is the cost breakdown:

1) Yamaha FZ Master Cylinder - Rs. 1155
2) FZ Brake Lever - Rs. 95
3) FZ Banjo Bolt - Rs. 9
4) FZ Front Brake Light Switch - Rs. 80
5) Pulsar 220 Steel Brake Hose - Rs. 1110
6) FZ Master Cylinder Kit - Rs. 190
7) Zip Tie + Connectors - Rs. 10

Total - Rs. 2649

Some pictures:

A big, big thank you to Sunnyboi, without whom, none of this would've been possible. Be it the idea or the execution!

EDIT: The right mirror is barely useable now. Reason being, the thread for the mirror is located right on top of the handle bar and not near the brake lever as it was with the stock Master Cylinder. Also, the thread reverser is also rendered useless now. So will have to look for CBZ Xtreme mirrors now!

The mirror is visible in the 1st picture with the exposed wiring.



This is after applying a few fixes:

1) The wiring has been fixed
2) The hose has been secured with a zip-tie



Also, I changed back to the stock CPR8EA9 plug. Mileage is 48.5kmpl now.
