It would suck if the internals totaly change and there are different parts needed for the Gen 5 range, the GX range and now the MG66 range.
I thought the new gx line was really a gen 5.5 with coated parts and pretty heads. As far as the con rods I thought that 4-5.5 were the same. Just porting was changed along with the cranks, carbs. But they all took the same crank rod. Mark from massive mods,22racer or grizz would be the ones who would really know. I wouldn't be surprised if you could take the crank from the gx line along with the new con rod and put it in your go 5.5. along with the carb. as soon as they appear on ebay I plan on trying it.
