elctb Posted November 29, 2009 Report Share Posted November 29, 2009 I recently noticed that the fan on my 2007 TXTPro 300 is running almost continuously. It shuts off on occasion, but is running more than it used to. The bike doesn't overheat though. What do you guys think the problem might be ? Thermostat or water pump ?

cosmickites Posted December 10, 2009 Report Share Posted December 10, 2009 i dont have an answer to that, but after a tip over in a puddle yesterday my fan "whistles" when it runs. Any thoughts on this? i was considering just unhooking the fan as i ride the bike in TRAILS, not trials, so it gets a fair bit of air over the rad.

lian Posted December 10, 2009 Report Share Posted December 10, 2009 (edited) elctb, i have the same "problem" but don't know why it always whirl and sound like spaceship...wiiiiiii! and 300cc model too. Edited December 10, 2009 by Lian Link to comment Share on other sites More sharing options...
elctb Posted December 27, 2009 Author Report Share Posted December 27, 2009 Well, I changed the thermostat and the fan still runs as much as it did before. I would estimate it runs 60-70% of the time. It might be normal for it to run that much. I'll keep riding the bike for now. Link to comment Share on other sites More sharing options...
lian Posted December 28, 2009 Report Share Posted December 28, 2009 (edited) Recently have read that cylinder can be warm more cause carb did not regulated right - give richer mix. And from long work on rich mix will generate snuff in engine and muffler. It cause decreasing power, shoots from silencer and overheating cylinder, so cooler will work almost always... Check mix, maybe I need too... Edited December 28, 2009 by Lian Link to comment Share on other sites More sharing options...

elctb Posted January 2, 2010 Author Report Share Posted January 2, 2010 I've checked the coolant level and it's to the top of the radiator. Is there an easy way to check the impeller ? How can I check the impeller is working properly ? Link to comment Share on other sites More sharing options...
matt_urban Posted January 2, 2010 Report Share Posted January 2, 2010 can be lots of things myn runs most the time they dont run much cooland and the rad is small so dosent do much if its on more than it was before check your still using same fuel and oil mix and same oil quality then check water pump impellor for broken fins and play and check you plug is not to dry or to wet maybe change it anyways thats all it can be really if your stat is new Link to comment Share on other sites More sharing options...
cosmickites Posted January 13, 2010 Report Share Posted January 13, 2010 any reason for the very loud whistling sound from my fan? sounds almost like a loud screech Link to comment Share on other sites More sharing options...
houseape1000 Posted January 13, 2010 Report Share Posted January 13, 2010 As for the sceeching, make sure theres nothing catching......sounds silly, but my old bike started screeching and it turned out to be the fan barely catching a cable tie !

cosmickites Posted January 13, 2010 Report Share Posted January 13, 2010 thanks its so tight in there (jokes aside) that its hard to get a good idea what the F is going on. i will try again and take a look. it could be something touching it Link to comment Share on other sites More sharing options...
gasgasmi Posted January 14, 2010 Report Share Posted January 14, 2010 The noise could be the bearings going out in the fan motor. If they are going out it could be slowing the fan down therefore causing it to run more. If it isn't rubbing I am guessing you need a new fan motor.
