Shifter Shaft It Wasn't! UPDATE update

I put 300 miles on the Morini yesterday, It ran great until 60 miles from home the shift lever would not return. It stays down on the down shift and stays up on the upshift, more stiff than jammed I would say, Any Ideas?

Looks like I will be splitting the cases to get at this one.

I'll be looking at the Springs on the gearshift spindle

Can anyone guide me through a shopping list of things

THAT I MIGHT AS WELL DO WHILE I'M IN THERE???

So far;
1) Gasket kit
2) oil seals

It's a "76/'77 A3 09*** Strada (very nicely "Sported") It's a daily rider that will see track time
a few times a year, I don't want to get too crazy, but, you know,
while I'm in there....

Can't think of much apart from just putting it all back nicely. I hope you find a broken spring or something tangible as the cause, I don't like mysteries.Of course check the bearings if you wish.( I am more used to shimming end float in BMW gearboxes after they have wiped out a bearing but in the Morini I just put it all back in) I only gave mine a quick look at. probably could have made more effort but it all works.
I renewed the neoprene seal on the oil pump side and had forty fits worring it would drop out of the cover by the time I had got used to reinstalling it with the kickstart mech. I stuffed a new gasket in this process and tore a new clutch seal. Smoothed some Hermetite gold on to it and it never leaked. Now I know better.
Let us know what you find, then I will know what to expect!

Thanks for the advice 3pot.
Was going to get started on this tonight and realised that the clutch lever is almost impossible to bring to the bar. (Herculean effort!)
What does this mean????

You'll have to look at that clutch and clutch pushrods.I assume that with the cable disconnected from the clutch arm it is nice and loose. Was there some free play before the event? It's only a tiny clutch compared to my BMW so should not be heavy.

God I love it when I'm wrong. Turns out the rearsets were jamming up
(Tarozzis) filed the pivot and cleaned/greased them up... works great!
F#@*ing rearsets have been nothing but bother.
Sprayed lots of 5way down the BRAND NEW VENHILL clutch cable and flushed out SLUDGE and DIRT. It is now silky smooth.
So, no need to split the cases after all....

Had same problem with my Tarozzi's on siezing up after a short period.

Once greased they work fine,

but not sure how often they will need doing as there is no provision for regular lubrication apart from removal....

Tarozzi's are the right idea and in some parts well executed but could have been just that bit better without too much design application.

Glad it is sorted. I have been wondering about rearsets, though in fact I am not uncomfortable on the bike as it it. Maybe I'll stick with the standard set up a while....
