Recently, I bought a brand new crankcase for the subject engine to replace the one on the engine I own. The two crankcases are identical EXCEPT the new crankcase I purchased needs a different size (larger OD) rear bearing. With my digital calipers the bearing I need has a 23.87mm OD.
Is there a source for this bearing? I've searched eBay and other sites and the new bearings they show for the ST G20 .23 seem to be the wrong sizes.
Thanks.
