I have a Dynoport can for my 2001 Mach Z w/DPM.
I had it installed last year and had problems (not related?)
My center piston blew twice.. Bomby investigated the motor and determined that it was caused by a faulty center bearing/seal..
My question is should I re-jet before I put the can on this year?  I have to break in the new motor first.
I wrote to Rich from Dynoport and he said that although my sled should not need to be jetted for the can, that he always went 1 jet size up on the center carb with his Rotax triples but only if he had a problem..
Sled is stock except for Boyesen reeds.
