Still i reckon you've got a little leak somewhere in your new system giving you the ticking noise.

. Hmm... do you know when you open the black casing on the side of the gearbox, has 3 - 4 bolts on it, think it's the inspection cap, will it gush out oil or will it be ok? This screeching noise seems very clutch related, just whip her out, there one of the easiest gear box's I have ever removed![]()
... used to do that noise on my old clutch too, a year ago.
my clutch had felt heavy so thats what caused the heaviness for me, have you tried adjusting your clutch cable yourself??? the cutch cable may be worn/overstretched, do you get a groaning noise ???
