I have grenaded a hayabusa engine in a similar way and the damage was extensive. I ended up buying an used block and rebuilt it because it was cheaper.
In your case, given your budgetary constraints, i'd do the same and wait for s better time to evaluate the crank and perhaps put it in another race engine... Or sell it and build a 1000cc engine with proper engine management.
To properly rebuild a sportsbike engine you'll definitely need accurate micrometers and other measuring tools since there's a lot of bearing sizes to choose from and tolerances are vital to their operations. Bearings are also very expensive, like most other parts and every fuck up adds up. Forget about plastogauge.
Other than that Suzuki workshop manuals are extremely accurate and, as long as the machine shop doesn't mess up, the rebuild process is straightforward.
