oil light

Postby trashtruck » Sat May 11, 2013 12:41 pm



took my 82 out this am to put some gas in it. started raining so i was in a hurry to get back home. some idiot biker forgot to turn the fuel valve back on and ran the carbs out of gas. duh. anyway bike gave me a real hard time about restarting. took 8 or 9 tries then i heard the first cylinder fire, second cylinder and so on. trouble is now i have a low end kind of thumping, knock and my oil pressure light stays on. bike has plenty of oil. i have a feeling that running it out of gas may have done something to the carbs and now they need a good cleaning and sync . that would account for the knocking, thumping as it appears near #3 at low rpm, under 2k. what has me stumped is the light.

First thing I would do is make sure that you do actually have oil pressure before attempting to find the cause of a "faulty" oil light. The light doesn't indicate "not enough oil" it indicates "not enough oil pressure." This is a Very Bad Thing, and can cause catastrophic damage to the engine if left to run this way.

ok, went to the local auto store and picked up an "el cheapo" oil pressure guage. hooked it up where the original sending unit was and cant get oil into the plastic line to verify pressure. if i hooked this up correctly and had pressure, the line should fill, after bleeding air, correct? if it does not, does this verify no pressure?

Correct.
No need to bleed the air, though. The gauge won't care if sees 50 psi of oil, or oil pushing air.

probably the next thing would be to drain the antifreeze, pull the front cover off the water pump,bump the starter with no intention of starting the engine and see If the pump turns.
The pump is direct driven by a chain along with the oil pump.

update: found and fixed the problem, pressure restored. the bolt fell out of the drive cog for the clutch chain. simple fix but i'm not sure what kind of damage was actually done. and yes, it does take 8 hrs to pull the motor and put it back in. thanks all for your help.

Short of tearing it completly down and specking every part and rebuilding it,I would add a full can of marvel mystery oil to a new change of synthetic oil and run it gently for a hundred miles.
Either it will settle in or self distruct.
Its a 50/50 shot.

Get a can of marvel mystery oil in it on the last oil change and run it easy for a while.
The MMO is like a salve after a gall stone episode.

It's all metal inside the engine and trans; no "salve" will repair any broken metal.

Agreed, what damage has been done, is done, nothing will reverse it!! Hopefully if you didn't load the crank too much, you got away with some light scuffing and an oil change will prevent any further damage.. Time will tell if the plain bearings in the engine (Main, big end and camshaft) where damaged or not. The transmission is mainly ball or needle bearings and they will run for a while without any oil feed, but plain bearings damage very quickly if not fed a regular supply of oil.. Fingers crossed all is well.

sorry to be all gloom and doom..

I also agree about MMO.It will not fix damaged parts.
I only suggested it because of it's nature of how it works.

How does it work???I haven't a clue..I'm not a chemist,just a user.
Just from the results of using the product and first hands on the part after use I have experience this...

A 78 gl1000..many miles...fair condition...I started using MMO with the oil changes..
I didn't notice any change but I continued to use it anyways.

2 years later,I rebuilt that engine..I found that the mains,journals,rocker arms,jugs,etc were extremely hard to resurface.Normal burr removal procedures that I've done many times before would not touch the metal....The hand resurfacing would not touch the metal.I had to resort to a machine shop whe cused me when he also had difficulties.
I discussed this with a Aircraft mechanic friend(old timer) and he informed me that to the best of his knowledge,The MMO creeps into the micro fissures of the metal and with extreme heat and pressure it bonds to it creating a "primer coat" if you will and hardens the metal.

With this guys problem,It may be too little to late but a few bucks for a additive that might help stay off a rebuild.....
I'd snake oil it up and run it.....Get as much as you can before having to replace the engine.

No,I am not a sponsor of MMO and receive no compensation either. :cry:
