no oil flow
no oil flow
the bikes runs but i have NO oil flow when i look into the spar. i took the cluthc cover off and turned the motor over and all the oil pump gears worked so i know thats not the problem. also i took the oil filter out and turned the motor over and very little oil shot out of that rod. so how come im not having any oil flow? whats tests can i do? this is so frustrating!!!!!!:mad: :mad:

The gears and shafts rotating does not mean that the pumps are rotating -- an internal pump pin may be sheared. You could disconnect the long vertical scavenge hose where it returns to frame, and test that with some known oil volume still down below.
Inlet filter plugged?, next easiest check, but in that case like a failed oilfilter pump, the oil would accumulate in the spars and starve the motor sump. Draining the oil to see where it is will give some clues.

Pull the inlet line off the back of the engine and see if oil will flow from the spar out . This will tell you if the frame is plugged up. It should pour out very fast. Get a bucket. If the frame is clean then reinstall the hose and refill the frame with oil. Remove the oil filter cover and filter. Start the engine for a few seconds. If no oil pumps out the cover then you main oil pump has sheared the tiny pin or the counterbalance shaft is snapped.
The scavange pump is easy to check also. Pour about half a quart into the starter clutch vent fitting. Reassemble and start the engine. It should pump that oil into the frame within 20 seconds.

Hey, just want to clear something up. We are only getting bits and pieces of the story here. From what Chris has told me you had little to no oil flow and then tried to drain from the clutch side spar. Nothing came out. He said you guys then stuck a metal wire up in there and sludge came out. Just from that you should have known something wasn't right and drained/flushed everything. Doing something halfway will only bring more problems and cost more money. Sounds like something has gotton clogged up.
Did the crank go on this before or something? Where did all the sludge come from?
