Ok product, but misses key part
" Bought this bottom end kit for my 01 yz250 and unlike the stock crank it does not use the collar to set the drive gears in the correct position. Due to inproper machining on the drive gear side my the gears had no place to seat against properly. So long story short I had to hand make a collar to fit on the crank in order to get the drive gear in its correct position. Other than that being the only problem this kit seams to be ok but unless you have the know how to make a collar or wiseco fixes this flaw I would not purchase. "
