Hitchen187 Posted January 24, 2014 Author Share Posted January 24, 2014 Lol oh joyous another job im goin to change oil crank seal as i seem to be getting the symptoms of that leaking with the excessive smoke out of exhaust and oil spitting out of exhaust manifold also seems to tie in with the running issue im having with whats been said above might aswell do water pump seal aswell then Link to comment Share on other sites More sharing options...
dt502001 Posted January 24, 2014 Share Posted January 24, 2014 Ok before you go ripping anything appart check the crank seal left for leaks,check the intake for leaks . The oil comming from the pipe might be normal if the pipe is old and never been de coked ,,baffel packing old and saturated with old 2t oil,and milky tranny oil does not always mean a water pump seal condensation form's in the cases everytime the bike is left to cool down after riding and over time it will mix with the oil. Have you been having to top up the coolant? Is the gear box oil level high? Its a 5 dollar seal and easy to change and worth doing even if it isn't leaking. But lets just sort out the running problem first OK? Link to comment Share on other sites More sharing options...
Hitchen187 Posted January 24, 2014 Author Share Posted January 24, 2014 I havent really ridden bike to have to keep checking coolant lol iv only topped it up after iv had carb off with the coolant pipes and iv tried the lh crank case seal wen i got the bike cos it already had the idle issue but the rpm didnt change it just stayed the same and with the oil it was spitting out of the manifold onto the exhaust im goin to do seals anyway just to eliminate them im pretty handy with repairing bikes just no good at bike diagnosis lol Link to comment Share on other sites More sharing options...
blackhat250 Posted January 24, 2014 Share Posted January 24, 2014 Ok ill check that iv noticed that it looks asif its been spitting oil out of the exhaust maniflod and on to the numberplate at back you think this is crankcase seal issue then I think you"ve confused the Tailpipe with manifold, unless you"ve a numberplate on front mudgaurd, Link to comment Share on other sites More sharing options...
Hitchen187 Posted January 24, 2014 Author Share Posted January 24, 2014 No theres oil on the numberplate but i had a bad seal on the front pipe were oil was spitting of inbetween the exhaust and engine Link to comment Share on other sites More sharing options...

blackhat250 Posted January 24, 2014 Share Posted January 24, 2014 If your having to keep choke on to run, then its fuel starvation, on the pilot jet system . have you another carb" to swap. so we can illiminate more . Link to comment Share on other sites More sharing options...

Moderator Airhead Posted January 24, 2014 Moderator Share Posted January 24, 2014 yes I misunderstood that, but in post 85 he said "No theres oil on the numberplate but i had a bad seal on the front pipe were oil was spitting of inbetween the exhaust and engine" so lets talk further about this joint? oil on the numberplate is normal for these bikes especially when they arent getting ridder far (cold) Link to comment Share on other sites More sharing options...
Hitchen187 Posted January 24, 2014 Author Share Posted January 24, 2014 No iv just siliconed it up Link to comment Share on other sites More sharing options...
dt502001 Posted January 24, 2014 Share Posted January 24, 2014 Then is it sealed or not? If air can get in there then it will affect the bikes running ,,you realy need to fix all known problems missing parts seal ect Link to comment Share on other sites More sharing options...
Hitchen187 Posted January 24, 2014 Author Share Posted January 24, 2014 Yeah the exhaust front pipe to manifold has no gasket it was/ maybe still is spitting drops of oil on to the dep pipe on front of bike could this leaking joint cause my issue Link to comment Share on other sites More sharing options...

Moderator Airhead Posted January 24, 2014 Moderator Share Posted January 24, 2014 and while you're at it check the power valve (PV) is aligned correctly When you turn on the key the PV will go through it's cleaning cycle (zzzt zzzt) then turn off the key, at this point the 'U' shaped cutout in the PV pulley should be in line with the 4mm blind hole behind it in the cyl head. Now look up the exhaust port, the top of the port should be perfectly flat and smooth if the PV is positioned correctly, not protruding into the port in any way at all Link to comment Share on other sites More sharing options...
