R6 is the correct size, ZZ or RS can both be used. I remove the inner shield to allow more oil to enter the bearing.

Johny,
You don't want the open R6 size... It is narrower than the sealed R6-2RS, and the R6-Z, at .2187", instead of .2812" and has a lower load capacity.
If you select the dual seal R6-2RS (or another notation for two contact seals), leave both seals on the bearing, since the grease it is packs with is a much better lubricant than the methanol diluted oil that the engine would expose it to.
If you select the R6-ZZ, do remove the inner seal, to fully expose it to the oil from the engine.
And yes, the rear bearing is a 6902... To make sure a failing cage/retainer would 'take out' the P+L on its way out, opt for plastic retainers...
Paul McIntosh of RC-Bearings offers them set up so for [link=http://www.rc-bearings.com/catalog/product_info.php?cPath=21_48_56&products_id=204]under $6-[/link].
