hey guys i am new to this site however not new to dirtbikes i picked up a 450f with a toasted motor for 200 bucks. everything else on the bike is good, too tech suspension, fmf pipe 2 sets of plastics. the problem is the piston went through the cylinder followed closely by the rod, so the major parts i need would be a new piston, cylinder, crank and rod assembly, and a new set of cases , bearings , and gaskets, lets not forget the oil pump which caused the failure, im sure after sifting through the debris. so in a nutshell i need a motor so my question is what should i do? piece it back together or try to find a mystery motor on ebay if anyone has a motor running or not i would love to take it off there hands.
