...stumbled across this site just now, via an oil-technology forum of all things, (bobistheoilguy dot com), and tho i usually buy my OEM parts from HoT (YoT), they killed YoT's prices by $70 on a crf450 head, and by $50 on the crank...i have not ordered anything, just found the site... https://www.zanottimotor dot com...
