ok so i bought this sled about a year ago with a blown engine and i got her goin and i didnt think it ran the best for a 700 liberty becaue when im stoped and i pin it it only goes up to 7000rpm but if i ease into the gas it goes raight up to 8000 or w.e so i looked at the jets and looked at the specs and it is suppose to have 440s in it and it had 450s so i put the stock jets in and the guy that had it before had a can on it thats why it had bigger ones in it and this is really pissin me off any suggestions ive heard of it might be the temp sensor or ves valves i need help lol
