Hey guys, thanks all for the help on the carbs runs great now. thought I was all done and ready to ride those hundred thousand care free miles on a goldwing. UHMMM... Seems that when shifting if the momentum of the bike is such to keep the driveline loaded there is no problem. But if the shift is a slow one, it feels like after letting out the clutch and throttling there is some play being taken up in the drive line. I put the bike on the center stand in first gear and marked the bottom of the tire. there is about two and a half inches of play back and forth at that point. I removed the oil filler cap and observed the output shaft as I move the tire back and forth. the output shaft moves exactly with the tire movment and doesnt appear to have any play in the drive shaft or diff. It feels and sounds like the play is inside the trans. the bike is a 84 1200 and only has 20,000 miles on it. I would really like to think that the P.O couldnt have screwed up a goldwing trans that quickly but once again Im at a loss. Any ideas or suggestions are once again appreciated. Thanks mike

Having read all I could find about this subject, I went and checked the rear wheel freeplay on my 84 1200A. In first gear, the freeplay was 21/2 to 3" before meeting resistance at each extreme. I then removed the oil filler cap and stick the rubber tip of a pliars handle into a little cavity on the final drive and held it firm from moving. Then I tested the wheel movement and got only about 1/4 inch freeplay. This tells me thatmost of this freeplay is coming from ahead of the point where I held the shaft. In the tranny? I don't know, but can this possibly be due to worn gears in the gearbox, or worn bearings, or what? Should I be concerned at all about this apparent gearbox freeplay?

As I was typing, it occurred to me to check for freeplay in every gear: Here are the results:

1st--25/8" 2nd--21/2" 3rd---21/2" 4th--21/2" OD---1"

Is OD straight thru or overgeared on this bike? Interesting

Thanks

Thanks all. I guess then that once we determin that most of that lash is not rear end related, we can put it to rest.Thanks for that pic, Twisty, it was worth a thousand words.
