hoping to revive the thread and keep the wealth of knowledge flowing. here is a crazy idea i have been throwing around. norra or vegas to reno with an IT490! so these were the WRs of their day, with higher gearing and bigger tanks. is there a difference in suspension between the IT and YZ? i see 490s for sale all the time in my area and the occasional IT490 for pretty cheap. so i think it would be a cool vintage desert racer. lets say i find a clean YZ, can i swap an IT transmission straight over? ive seen some info on the internet stating the IT was rated somewhere in the 35-40hp range and the YZ was in the 47-55 hp range. is there really that much of a difference in the motors?
