I was wondering if I should get the Boysenen Pro series Reeds with the stock valve or if I should go with the whole FMF ram valve and the reeds that come with it? I do a lot of trail riding, so I need low end power and don't need the top speed. One more question, do you think it's a good idea to move my needle to the 4th groove and put in a #250 for the main jet with the adjustments mentioned above or 3rd groove with #240 main jet. These will be the first adjustmens made to the 2000 Blaster. I am also putting in 9 filtered air vents.
