Yes they ain't cheap and you can probably buy a new engine case for what the kit cost, but it is a simple and easy fix that will get you back on the road quickly and that set of threads will be bullet proof from there on out, use loctite on all the mounting fasteners, had the same issues when I built my first bike, loctite was the cure for all of my engines fastener issues.

New case for $15 plus shipping

best wishes

Is it hard to install a new case ? That might be a wise investment
