Yes, I edited my original post because I was informed that also the rear bearing was sealed at both sides, I overlooked this in my first post. I`m not making any statements here, just asking for opinions regarding what to use for replacement. As always opinions wary some
Regarding the destroying of the engine, I don`t know if this engine is still under warranty or not, what I do know is that it is extremely expensive to ship the engine all the way over to the US to get a simple bearing change. To change the bearings really is a quite simple task so don`t worry about that poor engine beeing destroyed, it will be fine
I just don`t understand why this engine needs both bearings to be stuffed full of grease and sealed when none of my tuned twostroke scooters, mopeds or none of all my glow engines has this kind of bearings.
Well, maybe the safest bet is to just order 2RS bearings and not worry about the extra drag they produce?
