Hey all. Just having a few problemo's with my bike atm... I have a 2010 GSX650F, and it only has about 25,000km's on it... It's run perfectly for the last 25,000kms and hasn't missed a beat... Until now... Last weekend, i saddled up and went for a spin down to Wodonga (about an hour and a half from here) to visit some family. Went straight along the Olympic highway. The most boring and flat road around lol. When i arrived, i noticed there was coolant coming out of my overflow hose. "No problem" i think, as it was hot, and i thought it was just the coolant reservoir doing it's thing letting some coolant out as i had the bike serviced recently by a local Suzuki dealer. So i left it and didn't think much into it. The next day I rode home. The same boring, straight bit of road. When i arrived home and pulled into my driveway, I noticed more coolant on the ground (out of my overflow hose again) as i got off the bike. WTF? Coolant reservoir still full, so we're all sweet. I rode into work on Monday and Tuesday (about a 15 minute ride, and i always let the bike warm up for about 5 minutes before i take off), and noticed my thermo fans came on on my way home and back into work from lunch. Which again was fine, as it was hot. It does this quite regularly as i approach the end of my trip. Now here's where the penny dropped. The next morning as i rode into work, in the cold, my fans came on again. This had never happened before in the morning. I'd had a clear run all the way in, no lights, didn't have to stop at intersections or anything. So i decided i better check that at lunch. Well i got home, and as i was pulling into my driveway, for the first time ever my temperature warning light came on (The F's don't have a temp gauge, they just have a warning light that comes on when they get too hot). So i stripped the rear fairing down to have a look and found that there was still coolant in the reservoir. So i took the fuel tank off to do a better check (the geniuses at Suzuki put our radiator cap under the fuel tank, just for convenience sake ), took the cage back in and left it to cool down in my car hold till i came home from work to check the level. I got home and went and had a look. She's dry. Not completely dry, but enough to cause alarm. I took all the fairings, topped her up, gave it a shake and squeezed the pipes to get rid of any air in the pipes etc and let her run till it got hot to see if i could find a leak of any sorts. Nothing. It ran, it got hot, the thermo's came on, the thermos cooled it down and did their bit, they turned off. Ran like it should. No leaks at all. I did however notice this, so i made a video of it. It didnt go for the entire time, but when it got hot it started... I'm hoping it's something simple like they didn't bleed it properly at the dealers etc or something simple like that. The thing is though, I''d done about 1500 k's since they serviced my bike, up in the hills and around town etc and it hasn't had a problem till just recently. I've changed the radiator cap in case it had a little leak, and am going out to have a good long ride after i knock off here at work to see if it stops the problem. The coolant isn't oily, and the oil isn't milky, and the bubble flow isn't governed by my engine revs or anything like that, so it's not a head gasket... Just wondering if anyone else has seen anything like this or has any suggestions?
