Are the water cooled engines faster than the air cooled? I have heard the water cooled are faster. And also what is a good exhaust for a 84 atc 250R? And also stock top speed? Thanks for your help!!!

 

No, the Air Cooled 250Rs are not faster that the liquid cooled.They do however turn a little higher rpm, about 4 or 500 more.They can be made into quick machines.As for the best pipe, there isn't a whole lot to choose from, my suggestion would be LRD.Good luck.
