Change your bike from horrible to butter smooth

Change your bike from horrible to butter smooth

I brought this bike during 2016 sorry to say it could never give me smoothness of my old splender. Main problem I feel like hard mono shock... Back pain started and feel like riding a untamed horse not at all smooth even after repeated service. Service centre fail to provide me satisfaction. I met my local mechanic first thing he advised me to change oil to power one Castrol it give me much comfort than before, then local spare store advice me change chain and sprockets to IFB after changing it much more comfort,. Still I feel not getting the smoothness of my old bike. Then I got an idea change from paper filter to oil wet sponge filter made by myself. That was done miracle's on my bike now my bike is super with 3times more powerful and smooth, then I made a seat cover which can accommodate a scooter tube inflated, now my back pain is almost gone.. what I like to share is honda has a worst spare parts collection though bike is good
