Clutch arm spring broken

[motoOzarks]

Using oil "additives" can lead to sticky clutch performance on a  bike.

They don't rinse out all the way with a oil change either.  Don't ask how I know.

If you bought your bike used the PO may have used something in there you don't know about.

Have fun on yer trip.

Only additives I use are lead and zinc (both in my TVR).  Oil is maybe 1500 miles in and Mobil 4t.  Looks still brown.

I accidentally put maybe 1/4 litre of Castrol GTX car oil in my Blackbird once instead of the usual Motul Semi Synth.  The clutch screeched when pulling away afterwards.  I changed the oil and it still took about a 1000 miles to settle down again.  I know we've had war and peace on the car oil subject, but 1st hand experience goes a long way

Well I'm just going to start banging my helmetless head against the wall now.  Got an email from Hermy's that the gasket and a few other bits have shipped, clutch was going to be ordered today, springs are here.  Wouldn't you know it that in perfect British fashion she fixed herself.  500 miles this week and hasn't shifted this good ever.  No clunk into first, no hard shifting, nodda, zip, ziltch.  If this keeps up I will have a spare bike stocked on my shelves.

Well 10 days later, today the hard shifting returned on nearly every shift.  I just don't understand what could be wrong that the issue comes and goes like this.  Guess I will need to order the clutch after all.  Any thoughts on this?  Oil is Mobil 1 4t with about 1500-2000 miles on it, looks good and brown, at the proper level etc.
