I am overhauling my 2001 R1 and was wondering what rebuild kits yall would recommend? Also replacing all O rings from pipe joints as one was leaking, but the carbs were definitely not tuned right. The guy said he had them synchronized but that doesn't help jack sh*t if they aren't clear and tuned right. Bike ran very lean as well. Added radiator fan switch and silicone hoses when they get here. Along with the best coolant, that you guys use or have had luck with. Thanks
