Did something alot better. Took apart my DLE 55 and all the parts interchange with the RCG 50. Only difference was the rod needle bearing. The DLE 55 needle bearing is wider than the RCG 50, but they both share the same rod.
The cylinders interchange on the cases, the cases look and are the same. The porting on the RCG when compared to the DLE is different. The piston ports are different also.
So, here comes a new DLE 55 cylinder with a new piston assemby on a RCG 50 case. Results shortly on You Tube.
