  1. Turned out to be a seized oil pump, looks like moisture has been in it at some time. what i ended up doing was plugging the oil line at the banjo fitting and using compressed air from the oil filter housing determined the gallery to the head was clear. i took the side cover off and there is a feed gallery that goes to the main clutch then to the head. if anyone is curious to the oil flow direction the banjo fitting nearest the cylinder taps off this line. the gallery was dry so the oil pump then came out to reveal its problems
  2. @Frank Angerano see the attached photo. looks like an oil gallery that feeds the head. thankyou for your input sofar. ive now been able to download the manual for the bike so ill let you know what the outcome with it is
  3. Frank. From what it looks like externally the bango bolts and three way oil line are pressure feeding oil to the gear box, the head has an internal oil gallery that flows through the cylinder and into the head. which is why i was looking for a circuit diagram. i am only interested in the pressure side not the return. if one bango bolt is undone out of the 3 it would make zero difference which one it was as the 3 way pipe is interconnected to them all it only serves as an indication that the oil pump is flowing something in this case it is not. the oil return has a gallery in the head as well as the external lines from the timing gear cover baffle. does the 400cc bike have an external oil line to the head ? this is a different kettle of fish
  4. Yes i am aware of how it works, i was hoping someone had a circuit diagram to confirm flow direction. my initial thoughts were the pump had failed
  5. This is the oil line i have removed the banjo fitting from nearest the cylinder/head.
  6. this is a klf300b the oil to the head is fed through a port in the cylinder from what i can tell from the various videos pulling them apart online. the external oil line looks to feed the gearbox via the bango fitting which then splits to 2 other bango fittings
  7. The other oil (bango)fittings of the only oil line on it go towards the gearbox, i wouldnt have thought the oil flow direction returns to the head
  8. Im not sure of the year models of all 3 bikes, they all have the 3 point oil line though. i did remove the banjo fitting nearest the head on this one and ran it . no oil through the fitting. i can blow air through it and can get some movement visable through the valve ports in the head, i think we can look at the oil pump being removed as the next step. this motor might be better of as a parts donor for the other 2 bikes im starting to think. this was the easiest to get running of the 3 bikes.

  10. Thats why im looking for a circuit diagram, to see if i can rule out a blockage without tearing the motor too bits.. im hoping i can force some air through the filter or banjo ports to get some confirmation of flow to the head. the external oil line doesnt appear to feed the head oil gallery
  11. Hi guys New to the forum. i ended up here google searching for info on a bayou 300 i have here which has a nice squeek to it. looks very much like its not getting oil fed to the head. it was one of 2 bayous i got hold of to add to a third one i already had here. it looks like the previous owner had diesel in the sump instead of oil. its had fresh oil /filter in it but develops a squeek once it warms up. ive managed to work out the oil feed to the head is not getting anything so if anyone has a circuit diagram not just the parts manifest that would help out as im still looking for a service manual to download. Cheers
  12. is it possible for a mod to edit the first post that the links are dead to save scrolling through 5 pages to look in the download section?
  13. looking for a manual as well for the 3 bayou's i have here.. have one with an oiling problem to the head to sort out maybe worth a new thread ?
