Few questions on Stihl MS381 and Stihl MS460 Magnum

[MichMich]

Good afternoon Gents

I recently bought and assembled the MS460 kit that Farmertec sells. I upgraded it with a 54mm big bore kit, and it now has much more compression than with the stock kit.
This saw has also received a bunch of Stihl parts (rim,sprocket assembly, brake handle and mechanism, tank assembly, clutch cover, and plastic covers as well as recoil starter are in a package somewhere in the world, on their way to me). I've been told that this saw is now a 81cc model, but haven't heard about power...
Can anybody tell me the power output for a 460 with a big bore kit?

I also bought a MS381 off Aliexpress that runs like a charm. But, I wanted to know if it's still possible to find some OEM parts, like the recoil starter (currently sports a MS462-C badge instead of a MS381 one)?

I'm also in the process of building an all OEM MS461 around a crankcase I bought off eBay. Could anyone here give me some of it's history with the serial number?

thanks!

right starter on 381, just wrong badge. it will come off. dunno how easy 381 badge will be to find.

It's the stock starter that was on the 381. Only upgrade(s) I made are clutch cover, sprocket rim, Stihl Elastostart handle and chain tensioner, and the 462 badge (would have largely prefered a 381 badge, but can't find one...)
