I recently installed a D and D Y-pipe and power lite pipe onto my 06 Crossfire 700 along with an MBRP silencer. I'm currently running an orange spring and 71 g weights in the primary and an off white spring in the secondary with a D and D shift assist. The problem I'm having is a mid range bog with the power lite pipe that seems to disappear as soon as I put the stock pipe back on. Any suggestions on rectifying this problem? Maybe go to 73g weights? Thanks in advance for any input.
