thats why I like wiseco, they dont come apart. as for the reeds, replace them...carbon fiber will work slightly better than fiberglass (boysen) BUT the difference really isn't noticable to the avg person, but glass reeds will live longer than carbon fiber. before you start grinding on your cylinder with the dremel again, learn what you want to change, why you want to change etc.. sizes angles velocity and flow are all important.. 1 or 2 millimeters can make a huge difference for the better and for the worse. theres a lot wriiten and a lot of resources for 2 stroke knowledge, learn the basics then experiment and you will probably see some nice rewards, experiment with learning the basics and it will probably get expensive.
