dantxtpro Posted March 13, 2014 Report Share Posted March 13, 2014 I'm new to trials and biking so please excuse my ignorance. Recently purchased a 2009 gas gas txt 250cc pro and it's been faultless until today when after riding it I stood it up while I attended to something else and when I returned I noticed a small puddle of oil ( gearbox) I can't see any obvious sources and when it's cold it doesn't leak so I can only think that once it gets warm the plastic cover expands enough to allow oil to leak from this illusive hole crack etc. It looks asif there is oil on the bottom left clutch casing bolt... Going to run bike until warm tomorrow and re tighten these casing bolts. Any idea what torque these should be?? Many thanks Dan Quote Link to comment Share on other sites More sharing options...
bilks Posted March 13, 2014 Report Share Posted March 13, 2014 Hi maybe it was out of your gearbox breather pipe.if you laid it down.see pic 1 Quote Link to comment Share on other sites More sharing options...
baldilocks Posted March 15, 2014 Report Share Posted March 15, 2014 Probably gasket if not the breather as suggested. Clutch gasket is very thin but you can now get a re usable one from splatshop which is a better job. Quote Link to comment Share on other sites More sharing options...
guys Posted March 15, 2014 Report Share Posted March 15, 2014 Clutch is on the right side and breather on the left, Would be strange if the leak travelled all the way to the other side... Quote Link to comment Share on other sites More sharing options...
cwill83247 Posted March 15, 2014 Report Share Posted March 15, 2014 Check near kickstart shaft on the casing for any cracks .. That's were mine turned out to be .. Quote Link to comment Share on other sites More sharing options...
dantxtpro Posted March 21, 2014 Author Report Share Posted March 21, 2014 Cheers guys i fired it up the next day and let it run warm then wiped clutch cover dry and let it sit. On further inspection it appeared the kick start oil seal was knackered. Now got a whole bunch of new problems if you can help please check out the thread ( fouling on clutch cover, clutch drags) Quote Link to comment Share on other sites More sharing options...
