And yes, in stock a Mehran can go till 140 easily...a well tuned one can go till maybe 150.
A modified one on the other hand can go till 160 and that is the max that its 4 Speed gear box can handle.. And I mean MAX cuz after that, simply, the gearbox wud break..
Mine does 160 easily and has enuf torque to do it. If I release the accelerator for 2 secs at 160 and then hammer it down again, it regains the speed in seconds.
I'll post the pics soon.
