Recently installed the RST clutch and lightened steel flywheel. First aftermarket clutch I've had. Very happy with it as a whole, I've put about 500 local traffic miles on it over the past 2 months, so I'm assuming it's broken in.. I'm not sure if this is normal, but if I'm in 2nd gear around 1800rpm, 20 mph, I get a buzz, (maybe chattering?) kind of sound for a second or two before I increase rpm's to over 2k . I can work around it by shifting from 1st to 2nd at higher rpm/mph, I do not get the noise. It's only at slow speeds that this happens. In neutral at idle it's very quiet, no chatter at all. Anyone else have this experience?
