Picked up a 2003 WR450F yesterday for my Dad. The previous owner put an Edelbrock on it, pretty impressive carb, wish I had one on my XR. I looked around, but didn't see much in the way of tuning this carb, I have a couple extra needles for it, not sure what is in it or how many clicks/what position it's set at right now. I was wondering if someone could give me a starting point to tune from. The bike has an FMF pipe, and my elevation is 4500, running up to 8k or so (I believe the bike was set up for < 1000ft.) If someone could give me a starting point (Needle and position) for this altitude, I'd appreciate it.
