rh-dt100 Posted January 29, 2012 Share Posted January 29, 2012 Hi I am still looking to cure my DT 100 fault. It wil not pull at anywhere near full revs under load on the road. It will rev up on the stand but will just not pull. I have re built the carb, cleaned the exhaust out etc etc. I have put it at the back of the garage since September (in frustration!!!!), but I really want to get it running properly if I can Could I be loosing crankcase pressure? If so is the cure an engine strip down to replace the gasket (s)? Many thanks Link to comment Share on other sites More sharing options...
Moderator Airhead Posted January 29, 2012 Moderator Share Posted January 29, 2012 crankcase pressure problems are usually caused by the crank seals wearing and can often be replaced with the engine insitu although not always. RH seal tell tale is burning oil and smokey and possibly a smell of fuel in the oil LH seal, take the cover of the magneto and see if theres any oil residue hanging around in there...or petrol, start the bike and spray the seal with WD40 through the slots in the rotor, listen for any change in engine tone it might be an idea to test the resistance of the ignition coil and the charge coil in the magneto...compare the the specs in the manual Link to comment Share on other sites More sharing options...
