Default Whining from trans after adding syn

I have a friend with a 2003 Sporty 883...totally stock!
She has 1900 miles (doesn't have much time to ride)..
I helped her change her oil in the trans, switch from standard to Synthetic (HD).&nbsp\\;\\\\\\; Put enough to the oil was up to the bottom of the plate in the primary.&nbsp\\;\\\\\\; The trans now has this annoying whining sound coming from it.&nbsp\\;\\\\\\; It gets higher pitched as the engine revs.&nbsp\\;\\\\\\; She says it is shifting fine in all gears.

Is this because the Syn is thinner, is this normal?&nbsp\\;\\\\\\; Any ideas??&nbsp\\;\\\\\\; thanks..

How much oil did you put into the primary? I only calls for 1 qt. You may have too much oil in the case.

We filled it to the bottom of the plate in the primary as per the manual. I think it ended up being around 24 oz.

As I understand it should be a full 32 oz in the primary.&nbsp\\; Did you adjust the chain tension as if too tight it can cause a whine.&nbsp\\; I went from dino oil to synthetic in my 07 and didn't experience any whine at all...&nbsp\\;

Agreed, I had that whine issue after the 1,000 mile service, I cured it by dumping the Syn3 and switching to Spectro 75/90. No more whine on deceleration, smoother shifting and clutch operation.

In that case you have too little oil. It takes 1qt. The fill to bottom of plate is for adding oil. @ 24 oz you are 25% low on primary/transmission oil.

the bike must be setting level to gage the level by sight and then it is a estamate. put the other 8 oz in and you'll be all set.

Ya what he said, that's the second time I've read about noise after not adding enough oil. It takes a quart
