Start without oil!

Today I made a serious mistake.
I have started the bike not more than for 4 minutes to make the carburation, but i had forgot that yesterday I had completely emptied the oil from the engine.
I immediately turned off the engine and put new oil (I more reignited for cool) and I used many times the kick start lever to operate the oil pump.
I noticed that the left cylinder and also the left pipe were much more hot than right side!
What could have happened?.
After 3 hours, with cold engine, I restarted and everything seems to be good.
Ciao.

If the left pipe was hotter than the right, in just 4 minutes, then this would imply that this cylinder was doing all the work.
What were you doing to the carburation ?

This doesn't sound like an oiling problem to me.
Good that you shut it down before big problems !

I was adjusting the minimum.
The bike was stopped by 25 years!

Hi Piero,

I think you are ok and I would not worry about it.

Years ago I had a simple on/off valve in my oil line to stop wet sumping and I would turn the oil off when I got back to my home after a ride

twice, yes twice, I started the bike and rode away without remembering to turn the oil on

one time I rode about 1/2 mile and then turned it on

another time I rode two miles before I realized my oil was turned off

I reached down and turn it on and continued on my way, with no issues

see, these things really don't need any oil at all............

ok, I screwed up but life went on and my bike still runs just fine years later now

by the way, I now have that on/off valve safety wired ON so I will never forget again

I live in a warm climate and manage to ride my Norton at least three times a week so I don't worry about wet sumping

on the rare occasions when I will not be riding it for a while, then I cut the safety wife and turn the valve to off

Yeah if ya sum up the stories its like dropping food on floor with a 3-5 sec rule so it you were quick enough to put some back in time then no worries mat'e. On the other hand no defense against best advice that requires complete renewal now or riding with a dark cloud sigma. I'd never be able to live that reputation down like the one sheep ever I dated, now and then.

We useually lock someone in the closet for two weeks if they do something like that .

' Someone ' said their mechanic ( the new enthusiastic one ) took a GS Suzuki to get the Rego ,
when he got back they found it hadnt been oiled ( New ) as they drain them for shipping . Obviously a trace in there .
Said they did a Admiral Nelson ( Blind Eye ) . Had no complaints from the purchaser , so wasnt catastrophic .

No intoxicateing beverages for you for the next month . And you might be forgiven . Just this ONCE , no more . :wink:

I've seen a car engine lose the drain plug, run till seized, re-plugged/oiled and run another 1,000 miles.... THEN the con rod went through the block. YMMV

Re; “I noticed that the left cylinder and also the left pipe were much more hot than right side!”
At least you know that the hotter side that is firing OK and there may be something wrong with the fuel/ electrics/ spark on the cooler side.

Hi,
Please some sugestions in order to the left cylinder that was more hot than right.
The bike has a Boyer on.
But he is a 750 standard with 932 Amal on.
Ii dismount the carbs and the right manifold was broken a piece to the left stud fixed on the cylinder head.
Both the sparks plugs have fire from coils.
Please let me know where i must check.
Ciao.
Piero

Are you using a single carb or 2 carb setup?

If 2 carbs, then should be a synchronizing issue. This is a matter of cable adjustment, idle screw adjustment, and pilot(air screw) adjustment.

If using a single carb system, then maybe a bad spark plug.

Leaning the thing on the sidestand running isnt a good way to sort out anything .

Think you answered it youself . BROKEN MANIFOLD .

PHOTOGRAPHS dont need translateing . they speak ENGLISH . :wink:

That should ease pierodn's mind iup3dn but lower's my opinion of your scolding attitudes. Most stupid forgetful thing i've rode off on were leaving fuel taps off or a plug lead after investigation or swapping plugs out to get my buddy going again. Have had big leaks develop many miles away but caught in time to meet strangers and beg lawn mower or tractor/truck diesel oil. Oh yeah my very last trip with Trixie in late fall over flowing primary d/t rearward inner case bolt falling out, over filled and rode 20 messy miles timidly as could could home, arrived with nil oil left in engine but flowing out main shaft felt 'seal'. Rear fender dripped oil off for many weeks afterwards even after blottering much as could, a few times.

Here's what happened.
I changed the right manifold, the bike is started the first time, the engine runs fine, the carburation is good and the cylinders warm in equal measure.
Ciao.
Piero

P.S.: i loved the videos.

Now that is a new one on me, run out of oil and a manifold ear cracks off. No other cycle in the world offers such interconnected mysteries to ponder. Likely just freed up some hp friction burnishing to better fit and finish, which of course puts the electric conduction at risk next.
