i would suggest 2 inline coolers, pro design (not modquad,they are junk) impeller, some water wetter or ice, and the aluminum radiator.. i run all the above on my 392 cub motor and it runs right around 200 in the summer.. if it where a stock radiator i would say it would run hot.. you could put a bigger main jet in the carbs, that would help get the temp down but would kill some power.. its a bitch when u start putting a lot of money in these bikes.. u have a big ass hot motor, i would spend the extra money to protect it.. so i will say yes.. get it..
