Hey guys im just chasing some advise on my 02 wr426, after riding my brothers husaberg 570 ive noticed my bike has nowhere near as much snap in bottom end acceleration. Im not expecting to match it with his bike however a bit more bottom would be good. As far as mods go its pretty stock just had the airbox lid removed and #170main jet installed. What are some mods I could do to help this and also I have my eyes on a yz400 can, will this fit with my header pipe or are they different dimensions? Also im in oz so messing with the throttle stop and grey wire mod wont help but I was considering the yz timing, will this improve bottom end or just mid-top power ?
