Oil on my sperk plug

As the topic says, found oil on my spark plug threads on the #1 and #2 cylinders. #1 was the worst, looks like it was all the way up the threads. The plugs themselves aren't fouled with oil and they have at least 3,000 miles on them. Is this something I should worry about? I just dropped in some new plugs so I guess I'll see how those are doing in the next hundred miles or so. My bike does have a habit of making oil disappear, but it's in small quantities at a time and I figured it was from my leaky valve cover gasket.

If you have a valvecover leaking, it could well be leaking into the plug well, and that's where the oil on your plug threads is from.

While riding 1993 katana gas went into my crank case what caused this? And how do I fix it?

There is really only one way that gasoline can get into the crankcase, and that is through one or more cylinders. My guess is that you either have a carburetor that is providing a too rich air/fuel mixture, you have one or more spark plugs that are not firing or firing irregularly, or, in the worst case, you have badly worn cylinders/piston rings. Remove the spark plugs and look for a plug, or plugs, that are wet with gas, and/or black with carbon. Connect the plug wires to all of the spark plugs and lay the plugs against the cylinder head. Now crank the engine over and make sure that you have good spark (wide and blue in colour) at each plug. If you have no spark, or a small yellow spark, then you either have a bad plug (change all four) or a bad coil. If the spark is good then do a compression test on the engine. The compression should be around 150 psi and fairly close between cylinders (less than 10% difference). An engine overhaul is going to be needed if your compression readings are much lower than 150 psi or vary widely. If compression and spark are OK, then you need to check the carb(s).

Engine race and new spark plug is rust carbon every 5-10km

1.check your engine oil level. 2.check the silencer whether black smoke or blue smoke? in case black smoke, airfilter is blocked and improper air/fuel screw adjustment in carburetor. in case blue smoke,the oil burns inside the cylinder, check the valve clearance or the cylinder need to reboring or replacement along with piston....

Change the spark plugs.

If it still happens, it sounds as if you are not getting spark once the ignition heats up. That will mean replacing the defective ignition parts.

I sure hope the spark plugs fix it.

Use loctite anti seize on the threads and torque the plugs to 15 lbs.

Thanks a ton Donald...

Yes! this means that the OIL RINGS within the cylinder is weak and does not prevent the oil within to burnt out into the cylinder. Hence you are using up too much oil which is burnt out causing more smoke with reduced efficiency. A clear picture can be confirmed once the spark plugs are removed as oil smear on the plug will confirm. Also it is good to get the compression checked using a meter at the nearest service outlet. All what could be done is to confirm if the oil used was of the same grade, if lower it can cause this issue. Finally if the fuel consumption is also low with smoking it seems that you must get this work done ONLY with an authorised center as poor components can reduce the performance.

Draining some oil is the thing to do. It will probably take a few days for the dripping to stop. The cylinder walls are splash lubricated. Too much oil lessens the splash. Chances are that little or no damage was done. Install a fresh set of spark plugs. Before installing, compare the spark between 1 & 2 cylinder. If the spark is noticeably weaker on cyl 1, consider getting a new coil. Please rate my answer. Thanks.

First of get the spark plugs checked.they must be coming out loose, to causing smoke neat spark plugs.Get the spark plugs checked with meter.If plugs are very old and not replaced for long time, get the plugs replaced.------- Also the spark plugs gets power from coils.Get the compression test done for injector coils and cylinders.There is spark plug tester available at local auto part store.Remove each cylinder one by one and get the spark tested .To which cylinder there is no or low spark that can also be the issue. -------- The other thing to check is rec/ref .Get the voltage checked . Also for oil issue get the oil filter checked and confirm if oil is getting leaked or , oil is getting burned.crankcase breather hose may have spewed oil into the airbox and that can also cause oil smell.Also bad or loose o-rings at valve can cause slight oil leak. -------- first check this basic possibilities.If there is a short or loose part, then that has to be replaced, before getting it started and run.---------- This should help.Thanks.Helpmech.

Cross-threaded spark plug threads on 2007 stratoliner 1900. right , rear cylinder. What can be done without removing the head?

You need to get hold of the correct "TAP", with a get deal of care re-tap the original thread. Then replace the spark plug and all should be well.

Loose spark plug thread, can't hold my spark plug

looks like you stripped it out ? they make/sell what the call a heli coil kit the repair striped and worn spark plug holes if you never used one? it takes time and patience to do it correctly.
it comes with a re threading tool and a installer to install the new coil/ threads but one thing to remember is when doing a in frame porject you will suffer the problem of getting metal shaving from the rethreading into the cylinder which can be hard if not impossible to remove with out taking the head off

It might be a good idea to flush everything out with clean oil. And maybe clean the oil filter. And clean the crankcase and stuff.
