does anyone know if there is a dyna ignition or cdi box for this model? i think i read that the only difference between the xt and the xtx is the xt uses a vacume fuel pump. please help. i think my 700 has ample power now, but im a power junkie. the 1000 is to expensive for me, so im doing one thing at a time with my 700. any info will be appreciated.
