case saver to fit zongshen 250?

[RangaBlitzFanga]

ive managed to smash my engine case 3 times now and its getting old. it does have a flimsy piece of aluminium behind the sprocket but it hasnt done anything so far
i cant seem to find anything on ebay, and a broad search shows too many bike specific parts. any help?

maybe go to a welder and offer him a slab and some cash?
