Nitromethane Cylinder Liner Question & Connecting Rod
I removed the cylinder liner from my OS 46AX, 46LA and Thunder Tiger 46 PRO. I noticed the intake and exhaust ports were sharp, and not smoothed out. Would there be any benefit for me to smooth out or round out the intake and exhaust ports with a metal deburring tool or similar tool..... Or would that degrade performance or liner integrity... ?
I was also wondering if the connecting rod on these engines need to be balanced, or does the connecting rod matter?....
