I have got my suspension checked and my tuk tuk sound was from right chimta and goda rods were loose got one outer right kit changed now there is no suspension noise.
Secondly i had some vibration issue in my cultus which i was facing after getting new mounts but have got 2 genuine mounts firewall and timing mount now there is only 5 % or less vibration and sound of engine reduced to zero if you set your rpm at 800...i got them for 2600 and labour 600.
