cobluecrewfan Posted February 21, 2011 Share Posted February 21, 2011 I tried to find a previous post about this issue, but didnt find anything completely similar. I getting my '73 TX500 back to riding condition and tried to start it with the electric start. When I push the button, it sounds like it is engaging, then after a second or so, I hear horrible clanking coming from th left side of the bike. It sounds like a loose chain clanking around inside th cover. I took off the left cover thinking it may be the starter chain (the chain that engages the flywheel and starter motor) and I noticed when I looked at it, it looked to be a little droopy between the chain guide and the starter motor. But when I look at pictures of other guys similar bikes, they also have some droop. I dont want to purchase a new one if it is not that, but I cant think of what else it may be.

I just want to make sure I am understading you correctly, are you talking about the bearing that is on the starter motor itself, or the starter clutch that sits behind the flywheel?

Alan m Posted February 24, 2011 Share Posted February 24, 2011 starter clutch is behind the flywheel the chain from the started should run down to it a good tip wpould be to disconnect the chain from the starter and turn it over and see if there is any grinding from the starter bearings but to be honest a 73 motor will prob not have had the clutch bearing done in a while if at all if you don't feel comfortable doing it get a mate with the know how to do it and show you the ropes do it once and do it right do it twice and waste your night sounds taccy i know but when you do it right you will fell better for it Thank you for your help!
