2001 R1100RT - How much rear drive play is too much?

I'm looking at a 2001 RT, which I understand is pretty late in the model run. It has just over 36,000 miles on it. It's in reasonably good shape with stainless steel brake lines and fog lights. All the bags, manuals, a Clymer manual, and even some maintenance parts. The current owner had a new battery installed when he bought it earlier this year. Unfortunately, there are no maintenance records that made their way from the prior owner to the current owner. The current owner is an adult and there are no signs of abuse, but he admits to being mechanically challenged. I'm not afraid of doing the maintenance that the bike will need. In fact, I gravitate toward these bikes because the maintenance is pretty straightforward. I am concerned, however, about the final drive.

When looking the bike over with the bike on the center stand, I did the 9/3 and 12/6 grab and twist check. There is definitely some play. Maybe 1/16 to 1/8 inch on both axises. Is this a sign of impending crown bearing failure or just a need for swing arm bearing adjustment? If it is a sign of impending failure, how much would that cost to repair?

The owner is asking $3,300 for it, which is a little below what Kelly considers average retail for this vintage. I want some idea about what repair might be needed and what it may cost to use in negotiations. On the other hand, if this is a major calamity waiting to happen, I'd like to know if I should pass on this sample and keep looking.

Thanks in advance.

Get it checked at a dealer. That much play if correct can't be good but get a professional opinion. 36,000 miles shouldn't have any noticeable play.
 
Check for play with the brake applied. If the play is still there with the brake caliper clamping the disk it is in the swingarm pivot bearings. If it disappears with the brake applied it is likely to be in the crownwheel bearing.

If you can, inspect the final drive drain plug magnet.
Black fluff is normal.
Silver flakes are a sign of the big crown bearing failing.
Not a deal breaker but the price will need to drop accordingly
