This is the first video in my MXZ 670 engine mod series. This will focus on some of the basic things you can do to wake up your sled. This will work on most Rotax 670 motors, but especially effective on 1996-1997 MXZ models.
This video we replace the existing Needle Jets with 224-AA-3 and the Main Jet to PTO 310 and MAG 290
Future videos will be:
501 Rotary Valve Install
Y-Pipe Mod
Oil Injection Delete
Tuning for the mods
