I just put in an athena 144 kit . Jetting is spot on , ran great . It has about 3 rides on it no problems . Today the temp was about 20-25 degrees warmer than any other time it was ridden . It started to bog and lose coolant from the overflow hose . I pulled the plug and it is golden brown . bike ran fine for about 2 laps(5 minutes) before this happened . Do I need Bigger radiators ? Overheating is the only cause for the bog I can come up with . Everything else looks good no leaks anywhere . I run maxima cool aid for coolant . Any ideas or help would be greatly appreciated .
