This crankshaft is machined from a solid bar of alloy steel and will give you .175"more stroke than the stock Honda/Clone 196cc crankshaft with far more superior strength. This is the strongest material used for a small engine crank. When installed in a Harbor Freight Predator 212cc you will net a +.136" stroke due to the Predator's 55mm stroke OEM crank. You will need at minimum, our connecting rod #6265 or #6765 and a Wiseco 11132PS or 17-2677 for Honda/Clone or (11132P94/17-2756 in a 212 Predator) and a 6521 HD wrist pin to run this crank. The crank is properly balanced when run with these parts. Larger pistons may require the crank to be re-balanced.
* Pre-clearanced for the compression release.
*The 11132PS and P94 pistons have a thick dome which is designed to be cut down to your engine's deck height when using connecting rod #6265. You must cut down the top of the piston by test-installing the parts and measuring to see how much needs to be taken off.
* NOW AVAILABLE ARC connecting rod #6765 3.525" "Drop in" rod that does not require machining of the 11132P pistons in most applications, and can be used with the 17-2677 and 17-2756 3 ring Wiseco pistons for extra ring seal... WARNING "Do Not machine the top of the 3 ring pistons"
* The rod and crank are pre-clearanced for for most cam applications but some additional machining may be required with high lift/high duration cams
*The only way a non-adjustable flywheel can be used with this crank is WITHOUT a flywheel key.
