Your good to go. What suspension work are you having done?

Krannie, I am just replacing springs in the forks and shock at the moment. But i made a stupid mistake with my shock. I broke the bottom nut and removed the damper thimble or what ever you call it. Anyways the inner rod on the damper came out and i lost oil until i pushed it back in. I took it to the dealer to get get the nitro bled and oil filled and recharged with nitro again.:thumbsup: When all i had to do was remove the lower spring guide and slide the upper guide and spring out.. It was a long night working on the bike, called it quits after that bone head move. I cant wait to ride it and feel the difference on the carb and throttle screw.

I have 2007 WR450 and I am running Main jet:168, Pilot Jet:48, Leak Jet:50, stock pilot air jet, MSR fuel screw 2.5 turns out, Yamaha NFLR needle on 4th clip and Lexx MXE slip-on exhaust with spark arrestor in. I have done all the free mods, removed the snorkle from the air box, YZ throttle stop and I run the stock air filter. I ride in North Carolina in low elevations with usually high humidity/heat. This setup is right on for me so sounds like you should be good too, or very very close.
