I have a 93 evo was out riding when the rpms dropped the bike wanted to stall. It was only about a 15 min ride to where I was going. when the bike started to stall I also heard a squeal like a fan belt on a car. when I got to where I was going I checked the oil and the tank was all the way to the top. It was late at night so really could not do anything that night when I got the bike home it had to sit for a few days and when I checked the oil it was where it was supposed to be. Is it possible for the lines to be block enough to stop the oil from being pumped to the engine

 

Did the oil pressure light go on?

 

No light did not come on

 

no the light did not come on

 

Is the motor all stock? When it lost power, did it also run rough?

 

motor is stock. When I would slow down it would stall out the only way to keep it running was to give it gas or pull out the choke. What made me nervous was the sweak that came from the motor at low rpm's

 

Did it sound like this?

 

Some thoughts on your symptoms:

Stalling at idle:
Could be the manifold gaskets. If they've never been replaced, they likely could be old and no longer sealing at the heads. Also check the large gasket/seal that holds the carb to the manifold. When mine decided to fail (2006), I was a few miles from my house, and could 'limp' home by pulling the enrichener out. Not a difficult job, but I'd recommend cutting down an Allen wrench to get to a couple of the fasteners on the heads.

Squeal:
As 0maha posted, it could possibly be the cam bearing. The 93 has the INA style bearing, known to be problematic, especially if an aftermarket cam was installed and not replaced with a Torrington style bearing. Get this replaced ASAP if you track it down to the cam bearing. Bad do-do can/will happen to the engine if it totally fails.

The transmission output shaft bearing could be hitting the inner primary. This is caused by the nut which holds the drive pulley on, loosening up. A known problem, and one The MoCo addressed with an 'upgrade' kit (locking plate and drive sprocket) in 1994. When mine happened 'on the road' (in Western PA), it caused a loud squeal. And also dug a small groove into the inner primary. I thought a wheel bearing was seizing, or worse. In addition to the gawd awful squeal, the engine felt like it was 'missing'. Tell tale early warning of this, is a small leak of transmission oil, behind the inner primary, that will sometimes leave a small spot on the the floor. And other times wouldn't. The leak/drip can fool you into thinking it's coming from the outer primary (it did to me), so you need to get on the floor and check the area behind the inner primary. It doesn't have to loosen by much to cause this. I've had mine 'fixed' twice: Once in PA (1994 Chambersburg HD) and the other time in FL (2002 Kissimmee HD). I caught it the last time, before it loosened enough to hit the inner primary, by noticing the small transmission oil leak. A few years back (2015 local independent), I proactively replaced the OEM lock plate with a JIMS kit, which is a superior design IMHO, but rather pricey. IIRC, the dealerships were charging around 3 hours labor for this repair. As with most things Harley, you have to remove a lot of good parts, to get to the bad part. Loosening (and torquing) the large nuts on the primary chain is not something I'd like to do on the side of the road.

 

1, - does your oil light work?
2, - if you pull the return is the oil pumping out?
3, - will your engine crank over normally cold?

 

Sorry guys for not getting back sooner. The squeak sound is not constant it seems to more like a crank bearing as it makes a revolution at low rpms. Like I said it seems like the oil is being pumped out of the motor to the tank but not back to the motor. When I rode it that night for 15 min and heard it I thought I was low on oil but when I checked it when I got where I was going it was over filled, When I checked it 2 days later it was fine. That is why I was thinking there is a problem with it not being pumped to the motor correctly. when it sits it slowly drains some back to the motor
