SOURCE: I have a 1999 fatboy

On a '99 Fatboy, you can use H-D Syn3 20W50 engine oil in all three locations. But, you can use most any lubricant you wish as long as it meets Harley's specifications. Amsoil, Royal Purple, Mobil V-Twin, just check the manufacturer's website for compatibility. On the Evo engines, I use H-D or Mobil V-Twin synthetic 20W50 engine oil. I use nothing but H-D transmission and primary lubricant in those two locations.

Good Luck

Tightening primary nut on 1999 fatboy


Hi Anonymous, If you are talking about the compensating sproket nut you need to jam a large soft piece of metal aluminum or brass or a piece of hard wood on the bottom of the primary chain and compensating sproket to keep the engine from rotating. Then torque the sproket nut to 165 ft lbs. Good luck

I haven't had any problems with the balancing system. If the noise is coming from the left side, check the primary chain adjustment/adjuster. If it's coming from the right side, check the cam shoes. The shoes went bad in my '04 Fatboy and whined like it had gear drive cams. Good luck!

Hi Anonymous, I'm sorry but I just loaned my listening ears to the lead technician at your local Harley Dealer so he could take your bike for a test ride and evaluate the noise. Have a nice day.

Whining noise from primary case when you roll on throttle.


Clutch inner primary bearing gone or primary chain too tight. Auto adjuster on these bikes so more than likely bearing failure.

There is a whining noise from the primary side of engine by the generator is there a bearing on the out side near the cover?


No, the whining noise come from the primary chain as it spinning over the clutch and the sprocket motor.Perhaps the adjustment is too tight,this will cause the noise.Do you check the chain tight through the inspection cover on the primary .You need a 1/2 to 5/8 in free play.

98 fatboy engine noise.


Harley's do run hot, anywhere from 220 to 240 normally, and a little hotter this time of year. I suggest running a straight weight oil, and a little heavier weight in the summer. I use Valvoline VR-1 30 weight most of the year, and 50 or 60 weight in the hot summer, and I use Lucas 20w50 primary/trans for the primary and tranny. I don't bother with the extremely high prices of the HD oils. For the whining noise, you need to determine which side of the engine it's coming from. Whining will almost always be in the bottom end. There's nothing in the top end that should whine, and if there is whining from the top, it's usually an air leak around the carb. Start by checking the fluid levels in the tranny, and primary. These are the two most common areas to pick up a whining noise. If it's coming from the left, it's going to be in the primary, and usually this is caused by low fluid levels. From the right, it's going to be either the tranny, low fluid, or the oil pump. The oil pump is a gear type system. If you're running a light weight oil, say a 10w40 or HD 20w50, when the engine heats up and the oil thins, it can cause the oil pump gears to whine a bit, especially in the summer heat. So, check the fluid levels, if they check good, then change the oil, since the summer is coming to an end, go with a straight 30 weight. This should clear up the whining noise. If it doesn't, get back to me with the exact location the noise is coming from, and we'll go to the next level of diagnosing the whine, but I believe that this will cure it.
