Yo! New to this forum as I've just bought an SM610. TT seemed like a good place to come! So yeah, I have an issue. My bike will not start. There is no kick start on it (but I have a spare engine I think from a TE610? with a kickstart mech so I may swap it over). Electric start sounds rough as guts. Stripped it out (starter all checked out and cleaned and it's looking spot on) and found that the gear that sits on the crank with the one way bearing inside (I guess anyway!) doesn't always lock. It seems to turn both ways half the time. Can you buy the bearings from somewhere? Apparently it's the same as a TE410/610 as well but I'm a proper newbie to these type of bikes!
