I recently rebuilt my zrt 800, not my first rebuild so it's not as though im new to this. Ran great through the break in, or atleast the first tank of gas which was mixed. Put in fresh tank of super, took my sled out and it ran ok for a while but it was only running 7-7 1/2 rpms. then it began bogging and eventually died....acted like a gas shortage but the lines are full. Only new mod after rebuild was a set of k&n's. Other mods I have done are aaen triple pipes, v-force 3's, magic reed block spacers and then other clutching parts but nothing that would have any effect on the motor running. Any help would be appreciated.
