Just poured LM in my GS today .. Bike simply transformed .. Can't believe it's the same bike .. But i guess it's too early to comment now .. I'll post results after 500kms 
Got it for Rs.750 from Shamsi Oil Traders, Hyderi, North Nazimabad Karachi ..Thanks to @abdulrehmanrauf for providing map & @camry47 for providing further details ..
Shop owner's info
Name: Majid Shamsi
Contact Number: 0300-2114244
^ He is a very nice & co-operative guy .. When i reached there his shop was closed (Due to strike in Karachi) .. So got the number from his neighbor shop & called him up .. He said he's a few blocks away but will be there in 15-20mins .. Luckily he arrived on time
.. Opened up the shop & gave me this gem (and 2 Liqui Moly Keychains :P) for Rs.750 .. He said only 4 bottles are left now & new stock is gonna arrive after one month so Karachi guys hurry up if you wanna get it ..
Currently LM is only available at his shop .. Tried Khan Motors (Defence) & Al-hamd Autos (Ayesha Manzil) but they were all out of stock ..
