Mine starts to buzz around 115 klm (68-70 mph)...I can handle the buzz over that speed but it's a good reminder why I sold my last sports bike...I had to slow down.....and it's a good speed to cruise all day... noticed the other day that if I keep my front tire at about 26 psi cold instead of the 28 psi recommended the buzz isn't as bad....might also have something to do with the balancing but I'm ok with it. Cheers.
My VN2000 used to cruise smooth as butter for about 4/5 years. Now it vibrates at any n all speeds. Feet/hands/ friggin teeth. I know it's coming from the engine. But I don't know what could make an engine vibrate that much without doing serious damage. Going on my 16th year n still have no good answers. Runs great in every other respect. never leaked so much as a drop of coolant or oil. HELP ME !!!!!!!!!
