Jonathan Yeung NB48 2.2 2nd day trial at Laliwarehouse 20240803 

@trippjonesiii6566 Thanks. The chassis is breaking in well. The engine probably needs another liter of fuel before the break-in process is complete.

@trippjonesiii6566 I also can use the current stage of the engine in racing if time is limited. However, the performance and life of the engine will have a certain discount due to the imperfect match of piston and cylinder before the break-in process is completed. So, if time is available, a well controlled break-in process is recommended.
