i had an eg 144(99 cyl) kit on my 01 cr125(worked great!) but with the stock pipe on, the front tire hit the pipe.im assuming the 99 cyl is longer from front to back, i just lucked into finding out that a 99 pipe bolted up fairly easy and solved my trouble. now im going to put the kit on my 02, will the 99 pipe bolt up with the frame differences? any ideas, or even if i had to modify a pipe which pipe is the best suited for my 02 with the 99 cyl (144) is the boyesen flange enough shorter to aleviate this prospective trouble im about too face? thanks guys.
