Reducing Vibration Issues on 200NS – single cylinder engines are notorious for the vibrations when riding. Bajaj quality panels don’t help much either. I bought my 200NS pre-owned and it must have gone through several mechanics’ hands. More often than not, these mechanics merely focus on getting their job done as quickly as possible, and tend to miss out the little details – such as a bolt here, a nut there, a grommet here, or a slightly cracked plastic panel. Let’s face it, there’s nobody who has as much interest in the bike than the owner him/herself.
So, in my quest to learn more of my newly acquired machine, I had taken it apart several times. It was not until recently that I got interested in trying to reduce the vibration from the bike. Only to realised that some previous mechanic must have accidentally popped out the side panel rubber grommet! It’s missing – only a big lobang remained. So, I made a trip to UM to get the replacement grommet – $1ea. I had only needed to replace 1, but since I’m at it, decided to change all 4 instead (2 on each side). Then with the side panel off, noticed that a plastic piece was cracked – the one that holds the plastic mesh panel to the side panel. So I glued it back.
Next, realised the rubber grommet nut holding the windshield (if you even call it a windshield) was wrongly mounted. The bolt was resting on the plastic mount instead of the rubber grommet. So any vibration from the headlight unit will be transferred to the windshield. So wonder I was experiencing quite abit of noise around the headlight unit / windshield area when riding. I’ve never opened this area since I got the bike about a month ago. So it’s probably either the previous owner or a mechanic. But I’m glad I picked it up.
So, after these “mods”, my 200ns now rides A LOT quieter!! Probably a lot closer to when it was new! My next related DIY mod may likely include pasting some rubber butyl sound deadening material – like what they use in cars – behind the side panels and tank cover. Hopefully this would further reduce any cruising rattle.
