bk mod

hey guys,

ive heard u guys talking about the bk mod on the 426. i was wondering what it is and how hard it is to put on my bike.


It is the simplest mod you will ever do! You basically drill and tap a tab on the carburetor to limit the duration of the accelerator pump. Motoman 393 I think has it posted on his site with pictures. Also look into the blue wire mod. This mod works very well. My 2000 426 has both of these mods and it starts easily, has no bog, and is fast as I can handle. I have not fouled any plugs since the blue wire mod. Cya
