it could be like buckaroo said. i have a yx 125 dirtbike <i know 2 small 2 stroke> and i swore i had something in the engine making noise when i got to a certain rpm. what it turned out being is the pipe was rattleing a lil cause the springs weren't as tight as they should be. i just live with the noise cause i know what it is and well it is a noisy bike anyways. but i could have swore something in the engine was amiss.

 

Lost mine too, if you find any that don't look like they belong to you, they may be mine - lol.... I would look where I left them last but I suffer from CRS (Cant' Remember Sh_t) and don't know where to look...

Don't mind me, I just have my tongue tied around my eye teeth and can't see where I am talking...
