[QUOTE="Bill_RC1, post: 26201, member: 22517"] 520 SX Update -- rode the bike today for the first time. Will never go back to a 2-stroke and was able to clear those big doubles and table tops with no problems on the 520. Used to scream the CR250 to do what the 520 does amost at idle. Amazing bike. 18.0 offset clamps -- no head shake and the bike turns on a dime. T-4 ProCircuit exhaust -- nice muffler. Motor just runs clear thru the RPM. Can ride the whole MX track 2nd. Disconnected the crankcase vent tube from the carb and routed between the radiators. Only problem was that you can smell the oil. Question for other 520/400 owners -- when the bike is on the bike stand and in neutral when I roll the rear tire their is a lot of noise being generated. I know some is the chain but I'm concerned that some is coming from the front sprocket/trany -- just seams like a lot of noise from this area. 2nd - when checking for jetting with the T-4 Muffler do you check the plug like a 2-stroke for color and determine if it needs changing? Any help will be nice. ------------------ [/QUOTE]
