Hi all,
I just got my motor back and got it into the frame tonight and all that's left to do is install the carb, airbox and gas tank. Here is my prob. The 39mm FCR that I have came off of a 99 YZ400F. I've jetted it to about roughly what most people recommend here (50 pilot, 170 main, 3rd clip on needle from the bottom and also did the accel pump mod). I went to put it on and the f'er won't go into the boot on the intake manifold. I even put a little WD40 on the carb and the inside if the boot and still no go. I compared it to the stock carb and it's about 2 or 3 mm larger than the stocker where it goes into the boot. Any suggestions???
