Hi,on engaging my ts 150 gears up or down the gears make a not engaging cleanly noise but will engage with a bit of force(deafness helps)the clutch seems to be working ie the push rod opens the plates ,the bike was laid up 24 years ago ,maybe because of the gear noises ,any suggestions as to the cause ? and who can strip ,replace bits & rebuild for me as I dont have any extractors or special tools that might be needed .thanks Fletty
