Sled starts and idles perfect .....Low power and only revs to around 5500 rpm Carbs are good .... 125 psi both sides ....exhaust not obstructed ...New CDI ..Any ideas ?????
Check The Pipe For Being Plugged. Animals Build Nests In Exhaust Which Chokes Off Power Output. If Nessary Remove And Run Temporalily Or Replace With Known Unplugged Good Pipe And Try.
