Bhai G. Jitnay mun uttni baatein. Back in 1994 when my father bought me a CD70 big tank (black with pink sticker)for 47,500; everyone had a bloody opinion. Take it to 80km/h slow and steady after 500kms once otherwise it wont go above 60km/h for the rest of its life! Double sawari not at all!! After continuous ride of 5kms, give it a 10 minutes rest!!! Dont drive for more than 8-10kms even at the speed of 30km/h.
I did double sawari right from day 1. Simple reason that a two persons of 100kgs combined weight and single person of 100kgs, what is the difference? I did 500kms and then drove normally at 60-65kms/h. First oil change at 800kms then every 1000km. The head was opened first time at 60k mileage and in those 60k kms, how many races, 14th August without silencer, triple sawari etc I myself can't count. Hope this helps
