Bob’s fix for the continuous breaking off of the two lower rear cylinder mounting tab ears to the crankcase studs
See photo

My new homemade Honda CR 250 girdle brace bracket will be a fixed with two 120mm long M10X1.25 socket head cap screws……These will in turn will be attached to the lower part of crankcase with two M10X1.25 connector coupling nuts 30mm long to the existing crankcase studs present on either side of the case.

These extra heavy duty cap screws ( two ) and connector coupling nuts should make the CR 250 cylinder rigid enough to prevent the two lower rear cylinder mounting tabs from continuously breaking off
Thanks
