More likely a valve guide allowing a little oil to seep by, and when the engine is started, it gets pulled into the combustion chamber and burned, and comes out the exhaust as what you see. If it is just visible on startup, you don't have to worry for a while, but it will get progressively worse over time. Oil fouled spark plugs will be the final result. Of course it all depends on how much you use the Harley.

Catch caniron head sportster xlh spit oil after sitting for a while.Should I use a oil catch can to fix this problem?


Hi Anonymous, it's called wet sumpping. Evo's and earlier engines were famous for oil draining out of the oil tank past the oil pump check ball/valve and into the bottom end when left without starting for long period of time (winter storage). When the bike is restarted the piston downstroke creates pressure in the bottom end which is routed back through the gearcase, up the push rod tubes and into the rocker boxes and finally into the air cleaner where unspent fuel particles are recycled back through the carburator and into the combustion chamber. Oil mist and air are seperated by a baffling system in the cam gearcase compartment. Under normal circumstances there is only a couple ounces of oil in the gearcase and bottom end. If the bottom end has a gallon of oil in it, well you get the picture and the mess. Best way to prevent oil eruptus is to drain it before it has a chance to to relocate and take up residence in your bottom end. Enjoy the new season.

ADJUSTED VALVES AND NOW THERES IS SMOKE ON 75 HARLEY IRONHEAD


Hi Curtis, and the usual suspects are:
1. Oil tank/pan overfilled.
2. Restricted oil return line to oil tank/pan.
3. Restricted breather operation.
4. Restricted oil filter.
5. Piston rings badly worn or broken.
6. Valve guides or seals worn or crushed.
7. O-ring damaged or missing from oil pump/crankcase junction.

1973 Ironhead. white smoke from exhaust when started


Not uncommon on the Ironhead. As long as it's just a little white smoke for a short while. Probably some oil ran down the valve stem. You can do a compression test or a leakdown test to check the rings.

Good luck
Steve

I have a 1974 ironhead, starter turns but will not kick out .made bike into bobber none of original wire harness is used, I really have no idea what im doing when it comes to wiring. any help would be...


Maybe a bad solenoid in the starter. Check that you have a good ground to the starter. would suggest running wire from the battery negative post to the starter housing then try starting it. you may just have a bad ground if runnin a wire to the starter helps then you probably need to pull the starter take emery cloth or scotchbrite to where the starter meets up with inside of the mounting housing clean it up a little also the lip of the starter. or you may need to just run and mount a wire from the battery to one of the starter mounting bolts.
