    Hello guys.

    i'm on the road again, on a long trip around my country, and i'm having problems of overheating, i'm discarting posible issues like air on lines, coolant leaks, water pump issues, problems on the rads, but everything is perfect, so i was wondering, maybe the thermostat is close (or wathever the thermostat do when runs out), so any of you guys had removed the thermostat of your lc4? is any issues i should know about?, please remember i'm on the road, i have only basic tools,:cry:cry and no chance of buying new stuff for at least 1 more week.

    all the info i can get is more than wellcome

    Do the rads get hot to the touch when the bike has been running for a bit? This would indicate that there is indeed coolant flowing through them, and the thermostat is most likely not stuck shut (or at least not completely).

    When you say the bike is overheating, is it puking coolant out the overflow? Or is the temp light coming on? You had wired a fan, right? Is it still working?

    Hope you can get this sorted. :nod

    Can you beg or barrow a meat or candy thermometer and check the actual coolant temp. That would tell a lot.

    Are you sure your waterpump is OK? One day my bike got hot riding around town. I had low coolant from a bad waterpump seal. The bearings in the pump had seals that were starting to melt. It got that hot in there! Fixed it and now the bike runs cool again.

    finally i decided to go with it, i'm very far from any place where can i buy some spare parts for the cooling system, (this small town only has a ciber cafe as the super main atraction), so i decided to invest more time to find the real problem, i still think that the thermostat runs out because is the only part of the cooling system i hadn't replace ( i found that the upper hose from the thermostat is hot to the touch, but the lower hose, a smaller one is not tht hot only a little warm) , the water pump fine, no coolant leaks, so what the heck i'm going to disassemble the thermostat and see what happens:huh

    ps: thanks for the help guys i really apreciate

    once you pull the thermostat out, you can check to see if it works by putting it in a pot with water and heating it up. You'll see it open if it is working. It would be great to have a thermometer - maybe a restaurant will let you borrow one and their stove - but if not, at least you can tell if it opens by the time it boils.

    If you really doubt it works, leave it out, but remember it will take a lot longer for the bike to warm up.

    Good Luck!
