I just picked up my new 2000 440EX Big Bore. I have been riding it all weekend trying to get it broke in. I can definately tell the difference. I owned a 99 400ED before and there is no comparison. I have left the thing stock so far and I was looking for advice on what mods are working and what and where I should begin on this bike. All reply's would be much appreciated. Thanks guys.

 

Where did you get it done?
And what trinkets came with it?
$?

 

Put a cam in it, aftermarket air filter, airbox lid removed, aftermarket exhaust(I like the LRD or Big Gun complete systems), aftermarket rev limiter, rejet the carb or my best suggestion would be to get a bigger carb, one tooth up on the countershaft sprocket for more top end, the list goes on and on but this is a good start.
Oh Yeah, Hang on tight!!

 

Thanks norm440EX. I appreciate the advice and parts are being ordered as we speak. To answer the other questions I bought the 440EX in Nashville, IL. Holzhauer Motorsports did all the work. Right now it is just the big bore. No mods, but that is all going to change severely after it is broke in. WooooHooo!!!! Cant wait... Thanks again for any advice you guys have.
