tomato_racing Posted May 24, 2009 Report Share Posted May 24, 2009 (edited) Basically I've prepped the bike for the track but now I'm running into issues. I replaced the OE Coolant with Engine Ice and now the bike wants to overheat! To be honest I'm afraid I might have popped a head gasket but wanted to get some other opinions. Here's the rundown:-replaced coolant about a month or so ago with Engine Ice-noticed off and on that the bike seemed to be running a tad hotter than usual (190ish cruising)-Rode to MidOhio last week and it ran hot within say 20 miles of the track (~200) while at 65 mph-On the way home from MidOhio It started to run REALLY hot while cruising (220) and reached all the way to 245 when I got pulled into my house. Yes I know this is bad and I might have caused internal damage but I couldn't do much to cool it down. -Thinking maybe I just needed to bleed it better I went and bought another stupid bottle of Engine Ice to top it off and bleed it. It was a little low when I filled it but the overflow tank was still full?!-While topping the bike off I rocked it back and fourth and side to side then proceeded to run the bike with the cap off. (I didn't see any bubbles in the radiator like you would normally see with a blown HG)-Rode the bike again tonight thinking I had fixed the issue and it ran fine on he highway (180@80mph) but when I got down onto city streets it shot straight for 220 and struggled to maintain. I turned the bike off for about 5 minutes and went back to ride low and behold the bike reached 237 just sitting! Mind you this is after maybe 20 minutes of riding.Sorry for the long read but I don't know what to do from here I think Ill go back to stock coolant and see if that's the issue but everyone raves about Engine Ice.Any help is appreciated.

mrmako777 Posted May 24, 2009 Report Share Posted May 24, 2009 sorry it was late last night when i posted that. anyways, after re-reading what you wrote, it sounds like you bled it right. did you do it exactly like this? per service manual...2-18 PERIODIC MAINTENANCEAIR BLEEDING THE COOLING CIRCUIT• Add engine coolant up to the radiator inlet.• Support the motorcycle upright.• Slowly swing the motorcycle, right and left, to bleed the airtrapped in the cooling circuit.• Add engine coolant up to the radiator inlet.• Start up the engine and bleed air from the radiator inlet completely.• Add engine coolant up to the radiator inlet.• Repeat the above procedure until no air bleeds from the radiatorinlet.• Loosen the air bleeding bolt 1 and check that the enginecoolant flows out.• Close the air bleeding bolt securely.• Close the radiator cap securely.• After warming up and cooling down the engine several times,add the engine coolant up to the full level of the reservoir.Engine coolant capacity:Engine side : 2 400 ml (2.5/2.1 US/Imp qt)Reservoir tank side : 250 ml (0.3/0.2 US/lmp qt)Repeat the above procedure several times and makesure that the radiator is filled with engine coolant up tothe reservoir full level.

tomato_racing Posted May 24, 2009 Author Report Share Posted May 24, 2009 You know I dont think I ever cracked the air bleeder with the new coolant. I think I did when I had watter wetter in it but not the Engine Ice. I just need to rebleed it and get the process correct with the whole standing the bike up and when to remove the rad cap etc etc. Who wants to ride to Dublin and double check me and then go for a ride later? lol Quote Link to comment Share on other sites More sharing options...
tomato_racing Posted May 30, 2009 Author Report Share Posted May 30, 2009 I bled it really well last week and it ran ok.... yes just ok. Problem being that I rode quite a bit yesterday, low and behold it got up around 230 again. I went out just now with the bike stone cold and the overflow tank is full... what gives?!

exSRAaron Posted May 30, 2009 Report Share Posted May 30, 2009 Could be the head gasket or thermostat. But maybe theres still air in the system or something. When did u get up to 230 this time? cruising or in stop n go traffic? Quote Link to comment Share on other sites More sharing options...
gixxie750 Posted May 30, 2009 Report Share Posted May 30, 2009 with the rad cap on start the bike and rev it and look in the res bottle for bubbles. Check you oil level and make sure its not rising. Is you rad fan turning on? Quote Link to comment Share on other sites More sharing options...
tomato_racing Posted May 30, 2009 Author Report Share Posted May 30, 2009 I hit 230 in stop and go. Fan kicks but only slows down the temp from rising, doesn't stop it. Oil level is fine.My thinking is that I just have yet to correctly bleed the system. Quote Link to comment Share on other sites More sharing options...
exSRAaron Posted May 30, 2009 Report Share Posted May 30, 2009 it really isnt that hard to do, make sure theres so leaks or spots where air is getting in. Quote Link to comment Share on other sites More sharing options...
mrmako777 Posted May 30, 2009 Report Share Posted May 30, 2009 The fan should kick on at 220. Is it turning on? Quote Link to comment Share on other sites More sharing options...
tomato_racing Posted May 30, 2009 Author Report Share Posted May 30, 2009 Yes fan kicks and I've bled it and bled it time and time again and the overflow res just fills up and the bike starts to overheat. The bike only has 3500 miles on it, could my radiator cap coinidently gone bad when I swapped coolants? Quote Link to comment Share on other sites More sharing options...
