[vacrf150]

i just recently bought my son a crf150r,more bike than he really needed,but he has riden a few kx85s and a friends ktm85 so hes no stranger to a full race bike and handles himself well on it so weve started to think about racing it.witch brings me to my question.i want to change the coolant and reading the so called owners manuel it says unless you have the proper tools take it to the dealer,now im no mechanical wizard but it seems to me just drain all the coolant and flush really well and add new stuff,or am i wrong?

That's it. Just make sure you don't use tap water. Get some distilled water to flush. Use an air source to completely blow the system out, close it up, add new coolant.
