I finally got my new to me GL650i ready to ride. I switched around the throttle cables because the PO had hooked them up backwards. I overhauled the front brake calipers. I replaced the leaky fuel valve with a new one without the vacuum and sealed of the original vacuum hose that went to the petcock. Changed and/or added to all the fluids and pumped some grease into the zerk fitting on the final drive. I've done a few short drives and now I find an annoying amount of free play in the drive. On the center stand, in gear I can move the back wheel about 2 1/2 inches measured on the tire tread. There is no detectable noise from the drive when I'm riding. I'm guessing that I have worn out splines. Since there aren't many good riding days left this year, in the frozen north, I'd like to hold off on the repairs till it gets too cold to ride. Would that be unsafe? Is there any other place that could be worn to make that much shaft lash? Thanks for the past help. I don't know what I'd do without this forum.
