Just bought 05 ZX10. When I am stuck in traffic on warm days temps don't take long to get high. Jumps up to 115 C and starts flashing and depends how long sitting at a light right up to 118 then flashes HI. I get moving cools down to 110-114 , but won't take a few minutes to back up. Fan kicks on at 90 but doesn't do much. Here's the best part. Replaced rad cap first...no change...flush and fill with good bike coolant ..no change...bike shop replaced thermostat...they bench tested it said was fine now..I trust this bike shop. First day in warm traffic...ZERO change. Still hit high numbers and flashing temps. Suggestions??
