mga masters, tanong ko lang (although na discuss ko na to w/ master boknoyXTrm2001Xuvi2003), gano ba katagal ang lifetime ng clutch bago palitan? how many kilometers? and how do you know the symptons of a clutch that needs replacement.

napansin ko kasi to yesterday and this morning while I was driving. When I accelerate fast and reach around 3000 rpm, bigla na lang parang humihina yung tako ko, as in parang nag-flat out yung power. pero the RPM remains at 3000 rpm. when I decrease RPM, andun na ulit yung normal pull ng engine. pag high RPM lang nawawala. instinct tells me na baka it's either air in my fuel line or my clutch is slipping. Nag purge at binomba ko yung fuel/water separator ko last night, andun pa rin. yung problem. so I guess, palitin na clutch ko. whacha think? tama ba analysis ko?

just what to get more opinions... aside from mine and master boknoy's.
