Still not finding Neutral

I just replaced the stock slave to a nice Oberon.  Beautiful quality part.  It made a noticeable difference in the clutch pull and smoothing out gear changes.  I thought by changing the slave I would eliminate the neutral thing.  I more than adequately bled the system but it still cant find neutral unless I'm rolling.  My chain tension is to spec.  Am I doing something wrong here?  I don't have this issue with my other bikes.

Did this problem happen after changing parts?  Which parts?

I got the Oberon slave cylinder as well. Initially I had the same problem, so I bled it again at the master and the slave. I also did the "zip-tie the lever to the handlebar" trick for about an hour. Just before Icut the zip-tie, I gently tapped the clutch line with the handle of a screwdriver when one single air bubble appeared and floated to the top. While holding the clutch lever in, I cut the zip-tie, SLOWLY released the lever and screwed  the reservoir covers on.

Do the zip tie over night. When swapping out slaves it can be a real pregnant dog to get it 100% bled the first time. If you've got a vac bleeder or can borrow one you should hit it with that too

Also, if the slave you bought has a bigger piston diameter than the stock, it'll move less than the OEM one for each degree of lever pull. So just keep that in mind.

One thing you can do is adjust the pin that runs from the lever to the masters piston. If you lengthen it it will (until a point) translate into the slave piston moving further out.  Be aware that turing out that pin too far and making it too long will create a situation where the master piston will not return past the passage to the reservoir. When that happens you'll have a clutch slave that will not allow the clutch to engage. Basically it'll be stuck in a position like you had the lever pulled.

So, my advice is to bleed again, with a vac if possible and strap the lever down after that for at least a night. If you're still having issues after that - then start playing with that adjustment pin. A small turn goes a long way there - so turn in small steps (like 1/4-1/2 turn) and test.

IF you start to mess with that pin, be sure to keep the adjustment tools with you for a few rides. From personal experience I adjusted mine to far out and lost function of the clutch during a test ride. I had my tools with and a quarter turn back sorted it. But if I hadn't had the tools it'd have been near mile of pushing the bike home. On my bike (radial masters) you need a tiny 1.5 or 2mm allen and a small 5 or 6mm wrench.

Allens and wrenches of the right size can be found at Sears.
-Throttle's on the right, so are the brakes.  Good luck.

Thanks all.  I'm going to try strapping the lever overnight.  In the mean time, I'll look around to see if I can borrow a vac bleeder.
