06 YFZ450 Hot Rods crank 621

Recommended Posts

Hi all, rebuilding the top end on my 06 YFZ450 that I bought "dead" with a blown head gasket. 

 

I noticed the rod is marked Hot Rods 621, I think this is stock stroke and not a stroker, Am I ok to go ahead and install a stock size (95mm) 11.4:1 Wiseco piston and jug?

Welp don't do what i did and get a piston with a stock size 20mm wrist pin, can not use it with this crank, so my new Wiseco piston  has to go sit on the shelf and look pretty. 

 

The HR 621 uses a 18mm wrist pin and stock apparently is 20mm.
