I'am half way done my yz426 engine transplant into my 400ex everything has come together pretty well.My ? is what kind of gearing should I run I have to buy some new sprockets and a new chain,and it could get hard on the wallet if I have to buy a few before I get it right.My second ? is what do you think about a 450r rad in this project I hope that it will work becouse it is already mounted.I know that I should just go and buy a new 450, but thats no fun any help would be great thanks
