Hi there,

Got an 1985 Tri Z 250. doesnt run, cleaned the carb cleaned gastank, air nox, new filter, new spark plug, engine starts idles perfet, at first i cant it in gear because the gear selecter rod were broken, i replaced that and put in new gear box oil, so i can shift all gears but if i release the clutch lever it doesnt start driving, so clutch looks good, oil is new, i tried different setting at the clutch pressure srew as well as the adjuster at the clutch cable. clutch cable is also not broken.

Some ideas what could be the issue here ???

THANKS

Remove the oil filler plug and look inside with a flashlight while you or a friend is pulling the clutch lever in and releasing it. Can’t you see the clutch plates opening and closing?

Thanks for this Advice, yes its moves, we take a look with my endoscope cam, see Video here if the clutch pack moves enough

clutch discs looks good to me on the metal discs no blue color or similar

what could be the problem here ?


How much gearbox oil comes in, it says on the gearbox 10500cm3 ??? which seems a lot to me i filled in 1,0 Litre
