a leak in the clutch line will mean the clutch will start to grab even when your holding it down. this is because the pressure may be escaping slowly or quickly, either way its only a matter of time before your clutch totally becomes unresponsive (and cant be disengaged), this is of course if you dont keep the level of fluid up.
i actually broke my release fork monday night, so my lude is down for the next few days until the $80 worth of tranny parts come in and i can find 16 hours to drop the tranny...fix the release fork/TOB...and reinstall it.
