Hello, I am having a weird issue. I bought the bike in pieces. It had been the victim of a wheelie gone wrong. I put it back together. It runs fine except for the overheating. I have flushed the system. I have replaced the hoses. I have taken the time to burp it. I used a flushing chemical in it and did not realize it was supposed to be drain shortly after running it. I drained the chemical, flushed with tap water and put the new hoses on. Now I see a bit of oil sitting at the top of the coolant. It is like a few droplets. I was thinking I may have damaged the water-pump seal. But the overheating issue is driving me crazy. It does fine until I get on the freeway. Then it gets up around 225-244. It goes back down when I slow down. Also if I cut it off at the light it will increase in temperature then go down immediately after I get going. I know I am rambling, but there is a lot going on lol. I also took the oil filler cap off while it was running and there seemed to be air pushing out of it, like exhaust. I'm quite confused. Have experience with car, so I am able to fix it, I just need to know what is going on. I do not want to tear the thing apart for something minor. I have read through the forums, but mine seems to be unique.
