Hey guys, just bought a used 2001 YZ426 and I started to pull it apart and see what it needs today, couple of questions: 1) The left side radiator is caved in a bit, maybe a half an inch. It's caved in enough that the plastic things that direct the airflow into the radiator are all squished and probably blocking the airflow. No coolant leaks on a quick 20 minutes ride, bike did not seem to run hot. Should I bother replacing the radiator? If not, any problems leaving out the airflow director thingys? Leaving them in their squished state would seem to really block the air into the rad. 2) The airbox lid is gone, will this cause any problems? Took the bike out on a quick ride today, holy moly this sucker's got some grunt! Darn, if I knew dirt bikes were this fun I would have gotten one years ago. Super stoked! Any thoughts would be appreciated.
