Recently purchased a 09 fz6. Started having an issue overheating after riding for about 25-30 mins. Temps getting up to 240 or so. So I replaced the lower coolant hose that goes to the oil cooler bc I saw some slight seepage. And I also flushed the cooling system 3-4 times and refilled with engine ice and burped the system. I also replaced the radiator cap with an oem one. Went on a small ride around town for 30 mins with no issues. Went on the highway riding at about 60-70 for about 20 mins straight and the bike started overheating again. Any suggestions??

Hey so last night I picked up a 05 shadow 750 aero and when I got home noticed there was a t shape vacuum hose behind the rear cylinder with what looks like a yellowish filter. It’s unplugged and hanging there and I can’t find out what it goes to through the diagrams. (I’ll post pictures when I get home)
