is your belt adjusted right. if not thats your problem you should be able to turn 26" tires with out changing a thing.
when you replaced the belt did you put the old 650 belt in there if so its the wrong one. the new machines run the same belt. for KFX700, KVF700, KFV650SRA, KVF650I, KFV750I. this belt is wider then the old p650 belt.
