10w-40 mein zic aur shell check Kar lo Bhai

[boldpisces]

Liqui moly is the best product in oil but 10w-40 is not recommended grade from Company. 20w-50 mein kixx Yamalube PSO aur liqui moly bhi milay ga. 10w-40 is good only if you find it in api SG. Api SL is a thinner oil as compare to SG because of less zddp. Isi liye company ny api SL myn 20w-50 recommend kiya for better engine protection.

I don't trust ZIC a single bit, is liye koi mujhe qasam de k bhi ZIC kahay to I won't use it. Sorry to say bus mera zehni ikhtilaf hai ZIC se. Meri aik car khatara ho gayi thi ZIC use kar kar k, is liye I seriously doubt ZIC's originality. Shell ki bohat tareef suni hai, will try Shell if Liqui Moly won't satisfy me.

[adnanniazi_2000]

If I won't find any trouble with Liqui moly, i'm not gonna change the brand but maybe will change viscosity ... bus that's it.

[adnanniazi_2000]

@hamikhan ... I seem to agree with u. I feel I need to tight my clutch a bit, but don't know how (koi hansay na mere pe

[boldpisces]

ZIC original oil is good but not good for yb 125z. Still you can use M5 if you really want to try ZIC otherwise go with SHELL or PSO in api SG because this is the only standard recommended for yamaha and will make gear box smoother. Liqui moly 20w-50 also meet api SG specs so it will also perform good in yamaha engine. After all these brands a top notch brand exist which is Mobil 1 but that is not affordable.

Meray bhai oil grade change kay baad agr appko gear shifting mein koi mushkil pesh aa rahee hay tow clutch assembly kay pass say clutch ko thora sa loose ya tight krain INSHA ALLAH app ka issue solve ho jiay ga

[waqassaif84]

Yes Hassan dear u are right and today i am going to Karachi will purchase liqui moly 20w50 as discussed with distributor a hour ago he confirmed price of 20 50 is 850/- but just confirmed me mileage that after how much kilo meter should change liqui moly 1000 or 2000.

[syedshehryar]

Yes i am still using it very good oil it reduces the noise of tappets while speeding. And gear shifting is good enough fir me. It costs 650 in mardan kpk. The shop dealer told me that don't use 20w50 full synthetic in new bike. 20w50 full synthetic is good for old bikes not new engines. He recommended 10w40.

[boldpisces]

Good. I will also check this oil but remember that 20w-50 is recommended viscosity by yamaha and using 10w-40 in SL grade can be little risky in stressed driving conditions.

[boldpisces]

You can stretch that up to 1500 easily and there are few people who is been changing this oil after 2500km.

Fuel Economy of Yamaha 125Z (72 Km/L)

Asslam-u-Alaikum,

This is my first post at Pakwheels. I purchased Yamaha 125z at 08-08-2017 and calculating its fuel average from first day. I got 55 Km/L in break-in period. After that I experimented at different speeds. I usually refill after my weekly trip of almost 325 km. The minimum average I got was above 40 Km/L at speed of 100-110 Km/H for one trip in my total travelling of about 8200 km.Now I am sharing data of my 9 trips mostly at speed of 60 Km/H

Distance Liter Average
334 Km / 4.88 L = 68.44 Km/L
326 Km / 4.62 L = 70.56 Km/L
325 Km / 4.49 L = 72.38 Km/L
465 Km / 7.19 L = 64.67 Km/L
453 Km / 7.45 L = 60.80 Km/L
352 Km / 5.39 L = 65.31 Km/L
348 Km / 5.50 L = 63.27 Km/L
330 Km / 4.63 L = 71.27 Km/L
379 Km / 5.36 L = 70.71 Km/L
Whenever I got low average, either there was a second person with me or I drove at higher speed for some distance.

Distance covered after closing petrol valve
1.2 km at speed of 80 Km/h and got average of 54 km/L,
1.6 km at speed of 60 Km/h and got average of 72 km/L,
1.7 km at speed of 55 Km/h,
1.8 km at speed of 50 Km/h,
From above data, I calculated a formula for myself (not a standard formula, it may be wrong)
54 / 1.2 = 45
72 / 1.6 = 45
i.e Distance covered after closing petrol valve x 45 = Average per Liter
Note that I can get average of above 72 Km/L at speed of 50 Km/h
(but 50 Km/h is very low speed at long drive)

There is nothing special in my bike, I change Yamalube after 3000 Km.
I am getting 40 km/L and 72 km/L from same bike with same settings just different speed and driving style.

Some key points for this average are
1)- Speed of 60 Km/h
2)- Long drive
3)- Single person
4)- shifting to higher gear as soon as possible
5)- Idling at 1000-1100 RPM

[boldpisces]

Great average. Now Honda and Suzuki owners must will cry as those bikes do not produce such mileage and new hike in petrol prices is more painful for those owners.

[mibadb]

Great post Shahid.

[adnanniazi_2000]

Condi of plug at first tuning. @hamikhan

[Khurramchauhdary]

Please tell me one thing if during ride one accidently or kids on the tank pressd the self start button, what will happen?

[boldpisces]

Nothing will happen as it doesn’t work when bike is start already but it’s better not to press that button again and again.

[mibadb]

Nothing should happen. You'll hear a weird sound as the engine is already running.

i also purchased ybz on 08-08-2017

[boldpisces]

My purchasing date is 10-8-2017. Fuel average is around 50 and sometimes above 50 within City and I always ride it aggressively while never driven along a pillion. Between, I messed up my average due to some idiot mechanics because they changed fuel screw settings. After lot of research, I came to know that it’s default settings is 1.5 turn, since I restore it to that point, it started giving excellent mileage. I believe that it must will produce above 60km per litre average when cruising around 60-70 in 5th shift but I never had a chance to drive such long trip and also time is more important for me than average so I usually cruise it around 90-100 in 30 to 40km trip.
