I just recently bought a 03 F4i. Trying to replace a couple parts. My main concern is the gas tank. Dude had a stunt tank on it so im trying to get a stock one back on. Will any other CBR model fit its placement? If not where can I buy one besides ebay? The cheaper the better and color doesnt matter. If anyone is trying to sell one let me know. Also, 3rd gear slips under heavy acceleration. I have not whitnessed this yet. Am I looking at a trans replacement or clutch? He said he replace the levers and pegs so i was curious if it was possible that he never adjusted the clutch cable. Thanks for your help. Ill get some pics up soon.
