Bike cant rev past 10ooo rpm
If done carefully, second hand gear is ok so long as it has been handled properly, and the second hand top end is a complete kit, of KNOWN origin, you could get away with not replacing the rings, would depend on just how much you wanted to compromise the bikes repair. At any rate, you get what you pay for. New rings is a small cost against having to tear the engine down again if the rebuild ends up with no compression or blowing smoke,.... I would have put new rings in it.. Do a compression check across all cylinders to see if all looks ok.
If the carbies came of a wrecked bike(as did the other bits, they may well have issues with sitting around/stale fuel. Hopefully your mechanic DID clean up properly and throw in a gasket/service kit for carbueration.
He may not have included a tuneup in the price for the repairs, and the bike may need this also if the carbs are off another model(exhaust system on doner bike may be different also upsetting the tune).
I would be going back to the guy that did the work and see what he is prepared to do for you, or cut a deal on tuning the machine up.If you aren't too happy with the outcome you have now, time to find a new mechanic.
Aint nothing like a freshly tuned motocycle;)
Good luck with getting it sorted, happy to talk to you more. Cheers
