July 28, 200917 yr Hi guys, I recently got a trials bike (1999 TXT270) and have been having a few overheating issues. I've checked out the fan and thermocouple - everything is operating fine. The problem is I end up doing a fair bit of dirt road riding to get to the technical stuff, and the bike overheats on the roads. As an enduro dude, I find this kind of ironic since it's the opposite of what happens with enduro bikes. Has anyone ever tried fitting an overflow bottle to a trials bike to recover the lost coolant? It's only an issue on uphill dirt roads where the bike gets revved a bit in 5th. Flat and downhill roads are fine. Or should I just slow down and let the bike cruise at idle in 5th? Thanks.
July 28, 200917 yr Both of my bikes never dripped a drop......on or off road. Perhaps the pressure cap on your radiator is not functioning properly.
July 28, 200917 yr if you have filled the coolent up it may be a case of it being too full. The rad cap will relese water if the level is not spot on. Try leaving it for two rides and it should find its own level.
July 28, 200917 yr Gday, it also might pay to have a look and make sure the radiator is clean - no rubbish blocking the fins so Air can flow through. Cheers, Stork
