and gs has been in local market for quite a long time,, its good bike and has much better carb,,
if u want power gs isthe weay,, at least engine,chasis will not give any problem for a very long time,,,
had i been u ,, i would have gone for it,,
initially i wanted to buy it myself in 2009 but again i had to use it a lot and due to fuel prices i settled on 70cc chonda, my bike had to had to travel more then 70 km back then daily,,so a 70cc was a nice option,, fuel was above 85 rs to a litre back then..
