Whining sound on decel

[HOOLIGAN]

Hey fellas i just got back from a couple hundred mile ride and on my way home i noticed a whining sound coming from my primary (i think). It only does it during decel. I have never noticed it before. The chop still pulls good though all the gears and shifts like normal. I did notice a few drops of what i think is primary oil on the final belt drive. I'm beat and didn't tear anything apart yet, i just wondered if any of you guys have dealt with this before or have any ideas on where i should start mt trouble shooting. Also i'm due for the 7500 mile service as well. Could this just be the primary fluid is shot or maybe something with the tranny? My bike is an '03 Chopper LSD. Any input or ideas are much appreciated.

i had a noise like that and it was in the trans. I had john sach pull it and fix it.

I have a noise simular and when I changed over to Rev-Tech fluid in Primary it stopped. Hope this helps

if the 7500 is due, it could be the primary chain might need adjusted.

I had that issue as well when I got my bike and I tightened the drive belt and it went away. I was told by a bike shop it was to loose.

I agree this is probably the issue.

With yours being a 2003 you have a standard HD primary setup you should see this. Including 2 pics... one with a look of the clutch plates in and the other with the outer primary off and clutch pack is out.

Here's another shot as you can see the comp nut off

While you're in there... adjust the chain slack, and check the comp nut and tranny nut for tightness. Remember the trans nut is left handed. if they are loose, remove, clean, and red loctite.

Trans nut goes back on dry at 150ft lbs, remove, loctite, and torqued to 100 ft lbs.

Comp nut... not sure the spec as my bdm manual for the 2006 does have a comp nut. Alhall or some others like knotso or ray could tell you.

125 lbs on the comp nut.

On the left side drive models the original torque called for 150 ft. lbs. but then there was a service bulletin that bumped it to 165 to 175. But after I talked to a couple builders and I wiped out 2 stators I used an impact gun and set for 250 ft. lbs. Then a year later when I decided to put my belt drive on when I was removing the old components I noticed that the compensator was loose again but I caught it just in time. If you run a compensator like this I suggest that checking that crank nut be part of your regular maintenance program. And when I installed the belt drive I installed this baby and never looked back.
