Okay so here's the skinny , I recently swapped out my shitty looking primary cover for my 2007 Softail st to a nice chrome one , replaced the gaskets etc..
As you know the 2007 Softail only has the derby cover to add oil not like the Softails pre 2007 , my buddy was adding the oil and I watched him basically add a qaurt and due to the limited space he poured some oil over the clutch plates. I didn't nothing of it until yeasterday I took it for a spin and noticed when shifting from 1 st to second I really have to lift up hard or it stays in neutral ? The bike only has 10,000 kms and was fine prior to changing the primary oil. My question is will this subside with the more I ride it and the clutch plates dry off or do I have to take it in for servicing ?
The plates are SUPPOSED to be oiled, they're not designed to be run dry.
If you think about it, it would be kind of stupid to put a dry plate clutch inside a sealed housing (primary case) with a quart of oil getting flung all over the place by the chain.
My guess would be that your linkage may be a but out of adjustment or the oil level in the tranny may be low.
You might also consider putting a full synthetic gear oil in it like Mobile 1 75W90, Amsoil, Redline Shockproof, or Royal Purple in it. They do a better job of lubing the gears/bearings and make the tranny easier to shift than the usual 20W/50 engine oil that's generally put into them at the factory or a dealer servicing.
I changed mine to Mobile 1 75W/90 and it shifts lot smoother with it.
PS, If you don't have a Service Manual, get one!
Then go through the clutch adjustment. With different makes and grades of oil the clutch can drag a little making it harder to shift.

Ya...They are supposed to run wet. I believe you should fill to the bottom of the derby cover hole with the bike on the jiffy stand. If I'm mistaken someone let me know. I'm far from home and my shop manual.
yep,as stated the clutch is a "wet"clutch. when you say "lift up hard" do you mean the shifter has to travel a long distance? if so your shift linkage may need adjustment. if you mean physically hard, then I would suspect clutch adjustment.
Maby you overfilled? If you put 1 Quart in then it most likely is over filled as there is allways some oil left in there after draining. Just an idea. I also find lucas oil addatives help with smoother shifts. IMO
Thanks fella's I don't think I articulated exactly what i meant before and that's due to shift work and sleep depravation ! I know they are supposed to run wet hence the oil. My concern was if it was too much pouring the oil right on the plates themselves and literally saturating the clutch plates , as he poured the whole qaurt directly on the plates. I removed the derby cover heard small " whoosh " sound of air after removing the gasket checked my levels ( which were good ) replaced the derby , took it for a spin and low and behold it ran like a charm. Very strange , anyways thanks for the feedback.

Pouring the oil directly on the clutch plates will not hurt anything. Probably just a one time occurance. I would not worry about it.
