Example of knife and counterweighting
 

Thought you guys might want to know the differences in the KA and SR cranks. Both are great cranks, but the KA needs some work. I took this pic from Joel07 of the 200sx forums, gotta give credit where credit is do, but I laid out the geometry pattern.

once i get a 240 *sigh* (yeah it seems the world's against me...) i want to do a KA24 NA buildup. nuthin quite like all motor... less variables, more consistency.
