i recently bought my son a KX 80 big wheel and there is no oil in the forks. I know that they could probably use new seals but i think someone might have swapped the forks with a diffrent bike. How can i identify the forks for parts ordering info. Should i put some fork oil in them and see if it holds. If they get pressure in them will they be alright to ride as long as i watch the oil level? Someone also ground off the serial # off the frame so i cant find put what year it is for sure but there is a # on the engine it is KX080RE000602.
