Is there a turbine connected to the main crankshaft that creates pressure pushing the oil up one end and down the other end of the oil cooler? Would overheating to the point of failure, cause an immediate stall without performance issues or would the bike struggle then die?
No turbine - all pressure is supplied via the oil pump. Have a look thru the service manual - there should be a cut away drawing of the oil circulation system.
"Generally" there are symptoms of low / no oil pressure. Problems shifting, can't find neutral while running, running so hot it wants to stall at idle, etc.. If you're worried about oil pressure, there is a fitting on the right side of the engine that will accept a pressure meter (I've never done it, but know some people have).
My bikes got those symptoms man. Am definitely worried about it. The bikes after running for 10-15 mins wants to stall anytime i come up to a stop or pull the clutch in. Once it stalls shifting from neutral into first is pretty much impossible. It will shift into second though. Never had shifting problems before. Shifts fine when running.
The oil light never comes on, but the bike only runs for 5 mins then shutsoff and wont start for about 30 mins. When it shutsoff its instantaneously like somebody hit the kill switch. No struggle nothing. no performance loss beforehand. Throttle response is fine.
All of this happened after i hit a curb at probably 30-40 mph bike took a big fall, obvious impact to the left side of the engine, Just a big scrape but you know the impact went through the whole engine while running. Tomorrow i was going to rip apart my carb and clean it out, because honestly thats simpler and easier than taking the engine apart, but now im thinking the oil pump isnt working.
When were your valves done last? Aside from the problems shifting, they kinda have the same symptoms.
Is it safe to assume that you changed the oil last, with good cycle oil, and it's not low? Just gotta check.....
Last i checked it was between low and full so i topped it off. Never had the valves checked, have only had the bike for a year but its got 40k on it so they need to be. Bike ran perfectly aside from having to fix an oil leak from a bad crankcase gasket. Then i wrecked and believe it or not a month afterwards rode a about 20 miles from my friends house to my house, then 2 weeks later tried riding it again and did about 6 miles and then it stalled as i was coming up to a stop in my neighborhood. Gas in its about 2 monthes old.
I rode it every day up until then, never had an issue until the crash, doesn't mean its related though. The day of the crash was also the hardest i had ever ridden it, large group ride, redlined about 6 times without meaning too for a few seconds. Before then had only gotten to about 500 below redline. Rode the bike for three hours straight until hitting something. Before that had probably only pushed it an hour once and usually just rode for 15-30 mins tops most of the time.
Valves also got the same symptoms? By check it you mean measure the valve clearance?
You could have clogged your gas cap vent when it went over. After riding a while if it's not venting it can create a vacuum inside the tank and no gas will flow. Next time it stalls pop open the cap and close it. Then try to start it.
