Posted May 26, 200816 yr Hi and thank you in advance. I just got this bike and it runs great once you get t started. The problem is the starter drive keeps kicking out. I have a 1978 XS650 with the same problem-sounds like a bunch of marbles until it actually kicks in and turns over. XSmike.com sells a kit for the problem for the XS650. I am wondering if this is the same setup as the TX500. On the XS650,it is a problem with the spring behind the clutch basket. The spring is too weak to keep the starter drive kicked in and so it grinds and sounds like a bunch of marbles.I have not taken the right side cover off yet,thought I would ask if it is the same as the XS650 before I take it apart.

Its these buggers that flat off over time and start to slip. you need to get new dowls and springs from yamaha (you need 3) this relates to the xs400 and I'm sure they are the same for the 500.

Well,thank you. It is different than the XS650. The lower case looks quite the same as xs650. I am glad I did not take it aprt until I get the parts. Thank you drewpy
