@awaiz43 no one is replying you for your bike's issues.
Did you got any solution ore consult with your dealer ore any good machine??

[awaiz43]

1.I will try other yamaha forums. I plan to wash and wax the bike today and wait for some good suggestions but i think this is not going to happen as i saw most senior and experienced members r not replying these days dnt know y.
2nd option is to visit Bismillah autos the owner and senior mechenic there is very experienced.
3. So far i didn't try or check any thing except engine oil and i think issue will be resolved with some basic settings.
4. Kindly tell me did ur bike ever hit the speed breaker frm bottom?

[rizwan_ch8]

Yes twice hitted on speed breaker when my czn was sitting behind me ( on max load ).
I think double stand touches on breaker...

[awaiz43]

Yes it happened once with mine i checked the bike but no damage seen. Its double stand which hit the speed breaker and when bike is fully loaded. Bike never touch with proper made speed breaker those breaker made in small street r more dangerous.

Good morning.
Saturday the start of holiday late night i took a short trip to islamabad with ybz. Frm last 2 days bike is not as joyfull as it was b 4. 2300 k.m done with 1 tunning and 3 oil change. Prblms are
1. Whistle type sound when accelerator released. Even at low speed.
2. Bike is not producing power mean it feels hard. Viberations at 6 to 8k r.p.m.
3. Not feeling the ride smooth at all.
4. Bike is not clean engine rims and chain cover etc are full of mud due to rainy season. But this can't effect a bike so badly?

01 number adjustment bolt is for fuel setting i think. Pic is taken frm battery side. @hamikhan i studied plug and carburator basics yesterday. My bike is running on lean petrol setting. Or i think mje petrol bhrhana chye mamoli sa. Aap ne bola petrol kam kro kindly discuss this point.

[hamikhan]

Ics mein aik bolt idle speed setting ka hay dosra air fuel mixture setting ka hota hay i don,t know which is one for speed setting & which is for mixture setting 1 sided small screw driver lay ker bari bari donon ko rotate ker kay dekho jis say engine key speed kum zyada ho wo speed setting kay leay hay dosra say air set hoti hay 1 turn 180 degree anti clock wise open kro phir bike ko 8,10 kilometers chlanay kay baad pic dubara post kro

[awaiz43]

There is only one screw beneath the carb and it is for fuel adjustment. The idle rpm adjuster is on the side of carb. Plz note and discuss this point.
1. Mera bike lean chal rha hy petrol bhrhana chye or clock wise turn se petrol bhrta hy. Aapne kaha anticlockwise turn kr k petrol kam kro?
