Well Hi Guyz, Its been almost 3 years now from my last post related to the same problem which I have experienced from the day one when I bought my first motorcycle. I am putting the old thread link here below.
Pulsar 180 UG 4 steering woblling proble - Old Thread Link
Well so far I have covered more than 55,000 km roughly with my pulsar. My handlebar wobbling problem was never solved though. I did number of things to rectify it so just don't want to go through that history. About 8 Months ago first time I changed my Tires and I was hopeful that my front will wobbling problem( between 55kmph to 655 kmph) would at least minimize then, but surprisingly there was no improvement at all.
After some engineering I found out that the new front tire is not seating properly on wheel rim, its slightly producing an oval shape. Tire Shop owner from where I installed new tires invented that my rim is bent. With a heavy heart finally I decided to change the wheel rim too. But even after so much of effort put(in terms of money) it was still useless but not completely. I observed that now if I over inflate front tire (say around 30 to 34 psi) and maintain recommended pressure at rear tire, the wobbling actually disappears.
I feel that here over inflating the tire basically makes the tire stiff which eventually resist deformation under load. Therefore the tires overall diameter marginally increases. So that means if i upgrade my stock tires 90/90 -R17 (Static Load Radius = 286mm) with some larger tire say 100/90 - R17 (Static Load Radius=293mm) it should help me out with the wobbling problem. I don't care about speedo error with distance covered and actual speed which would occur due to tire size change.
So please help me out and please provide me your valuable suggestions and opinions about the same. Has any body seen or done the front tire upgrade on pulsars with larger tire? are there any other concerns I may have left unnoticed!
