overheating

Hi, about a year ago my timing chain broke because a nut from the valve adjustment unskrewed itself and fell into the chain. This happend in low speed/ 1gear. It was ’’easy’’ start at this time. Just finished changing exhaust valve and mounting a new timing chain, tensioner, headgasket etc...

I have a 2001 Husaberg FX 470e and it continues to overheat after idling in place for 10 minutes or more. The bike I believe is jetted properly I did the conversion to a keihin carb (FCRMX 41) with the suggested DMS needle and suggested jets. It runs great and starts very easily but when left...

Hi, Today's not been so good, just blew out the head gasket on the 450 due to a suspected heat problem. I had a problem with the 450 popping and backfiring on deceleration and an inability to set the idle low enough, thought i'd try adjusting the mixture PS on the carb while running before...

One way to reduce overheating on the 390 is to free up the exhaust.. does anyone know how to do this or have pics? I get told its easy but I can't work it out.

HELP!!! I have A FE390, it over heats in slow single trails... I have replaced coolant with a high grade coolant Liquid Intelligence... But it has only helped slightly..fuel boils and I get to 101 degrees. Any cost affective quick fixes. I already have a thermostat fan.

Hello guys, I am wondering if someone can give me some advice. Have a 2010 FE 570 with about 25 hours on it. Went out riding in the Rockies where it was a cool morning. Bike started to get very hot just going down the road at about 30 MPH. Easy riding in cool morning. Then got on the...

I have a 2011 570. Replaced the fuel pump last summer, solved the hot starting issue. Put a snowbike kit on it this winter and it now has overheating problems. I placed a fan on it and it seemed to work for awhile, then bike just dies again. It will start right up, but I can't go anywhere...

I've spent a lot of time and effort insulating the gas tank, putting fans on the radiators, etc. Still had boiling gas problems on steep slow climbs. So I bit the bullet and went the exhaust route. After 3 months, no problems. Let me know what you think. [attachment=1:2rmw5b94]new...

I have an 06 FE550 and lately I have noticed a lot of oil coming from the top of the engine, I searched the forum and tried the RTV silicon on the valve cover gasket and changed the valve inspection cover o rings as well. Next two rides oil leak is much worse and I am constantly boiling...

hi guys i have a fe 550e 2005 and i have an overheating problem, i dont have any water going into the oil, my radiator hasnt got any blockages, and im using good coolant. when i first bought the bike i replaced the oil and water seals for the water pump cos it was leaking out the hole near the...

Hi guys a while ago I was having overheating issues with my 550 so i tried out this synthetic coolant Liquid Intelligence 115, I must say it is amazing, the bike runs cooler and has never boiled over since we put this magic in it, my brothers KTM 525 also running this and as with mine no...

My FE 390 has always boiled gas and overheated; like my wife I knew what I was getting when I signed on. Two rides ago, I was over heating, boiling gas, and dribbling coolant out my weep hole 10 miles from nothing while trail blazing. In a hope to just get home I filled the radiator with water...

Hi people, I have new 2011 fe450 (20H) . it starts fine when the engine is cold but everytime it gets hot after some slow technical stuff the bike wont start. I let it cool for 20 minutes and it starts fine and works great, got have a cooling fan kit as well. I ride with 3 other freinds that...

Hi All, My dealer installed EE radiator braces on my '09 FE590. While riding an event on the weekend I noticed I had a coolant leak coming from the top area of the rads. Turns out the T-shaped radiator hose that runs between the two radiators and runs through the frame is 1/4-3/8 of inch...

Hi all, put a Hyde skidplate on my 08 550 recently and have a feeling the bike runs hotter now. Does anybody have overheating issues with this skidplate? Have you tried drilling a few holes into it to improve airflow around the motor? Thinking about that and would like to hear some opinions...

first off i've no personal evidence of this and wont ever ride fast enough to do so, but was talking at an event on sunday and was told that at top class competition level the shock was being found to overheat, believed to be due to its close proxmiety to the exhaust. this came 3rd hand from...

I've heard a number of times about installing fans so our bikes don't overheat. I just thought I'd mention that my 05 650 has never had this problem. I've ridden many times in over 100 degrees and really getting on it. I have only had the usual loss of a couple of ounces of fluid, never...

Had a little discussion with someone on another forum about the oil level affecting the engine temp. But can't really explain why this is. So, how exactly does a too high oil level make the engine temp rise? Regards.

Well went for another ride to mount disapointment yesterday the bike ran great except blowing its top two or three times i installed two 120 mm fans behind the radiator guards (they are now both smashed ,altercation with some shrubbrey :) the question i want to ask is i have a 1.4 bar radiator...

I have recently had the misfortune of loosing a lot of coolant and not knowing it, then continuing to ride for another 20 minutes. The bike became sluggish and a bit lacking in power, it coughed and spluttered a bit then stalled when I pulled over to check it out. It would not restart until...
