Gearbox /Neutral problem

Hi my 850 Mke3 is a great bike to ride but has developed an annoying problem
I can't get neutral from 1st gear. Thought it was clutch drag so replaced all the working parts in the clutch,everything now mics up to correct spec.,even put a seal on the clutch pushrod all to no avail.It's got to be something in the gearbox ( all new about 8000 miles ago ).It's quite smooth 1st to and 2nd and OK from neutral to 1st .Anybody out there had the same problem ?
If so what is the solution?

your primary or drive chain have the proper amount of slack?

Works from neutral to 1st but not the other way around? Bent forkl?

Yes it's got a new chain and new hydraulic tensioners so all well there. J

Thanks,will look at the forks when I have the box down

It certainly has the symptoms of a primary chain that is out of adjustment, as per Juice's comment. Perhaps one of your chain tensioner plungers is in a bind and will not allow sufficient slack in the chain? Or, did you put super-heavy weight oil in the primary?

Please keep us aprised of what you find.

Have you tried tqf or atf (auto transmission fluid) in the primary case?

My first question would be .... After you changed the clutch did it work any better ?

Had the exact same problem using the sintered bronze clutch plates. Replaced them with Surflex plates and problem went away.

Not sure whether you changed the clutch center or not . If you didn't take a look at the spines and see if they are worn.

Good Luck
