Hi Guys,
First off, a little about the bike. I have an 02 CR250 that I bought brand new when they came out in 2001. Just like most brand new bikes, it was as smooth as butter and an absolute rocket. Over time, it seemed to develop a bad vibration issue. A couple of years ago, I sent the engine to Eric Gorr to be bored to a 265cc. I was really impressed with the power gains but now it vibrates even more than previously (obviously). I have tried different handle bars (including flex bars) different grips, foam in bars, correctly torqued engine mount bolts, and many many more.
I enjoy riding the bike and use it for both motocross and woods riding. I ride regular enough that I don't feel I should be getting arm pump after 5 mins on the track or arms going numb after 30 Mins in the woods. I've been doing some research and was thinking about having the crank balanced. I would like to get some thoughts and feedback from you guys if you think it would be worth the money and help with reducing vibration.
For all you jokesters out there, No, I have not tried putting tampons in the bar ends..lol...I know that a 2 stroke 265cc bike will have some vibration but it just seems to be WAY too much. My buddy has a YZ265 with the same engine mods and it's like night and days when it comes to vibration.
Thanks in advance for you thoughts.
