I've had a number repaired and replated only to find the new weld cracks again very soon. Not always but in most cases.

Personally I'd be looking for another cylinder.

My warm up process is to start the bike, blip it up and down up to about 4500 rpm, led it idle for a bit then take off once the temp is about 50C. Then I wait till it's above 60C before I give it beans. It always hesitates in second gear for a bit, then pulls cleanly in 3rd and I know she's good to go.

Sound about right? I'd hate to break another cylinder.
