I have a 03 TFR-USA model and the latest thing to "fall" off is the clutch weight assembally. Should I tourqe the bolt that holds this all together down?? if so how many lbs?? it works fine for about 5 miles then it comes loose and throws the crank shaft outta wack and causes some massive knocking inside. Thanks for any help and suggestions hopefully someone here can help, cuz the lady at cosmo is a "not so nice person" to say the least.
