Regarding the unstable handling at curves, after running from pillar to post, I rummaged the net for discussions regarding unstable handling and the sort. On listing down the reasons for unstable handling on an A4 paper, I finished one full page. With the information available, I myself checked the alignment of the front and back wheels using the string method, and found that the two wheels were not in alignment. Next I found that the front wheel was not in the vertical plane. It had a slight slant. The top part had a slant to the left. Next I found out that the distance between the centre points from the swing arm pivot and the back wheel axle were not the same on both the sides. This meant that the markings on the swing arm for aligning the back wheels were wrong. Armed with these information, I approached PSN Yamaha, at Palarivattom, Cochin. They took the front suspension to a laithe, and have aligned the T-stem and the front forks. This has somewhat corrected the problems. I will be getting back to them after riding the vehicle for two weeks, when the parts bed in. Till then, bye.
