Hi guys.
I've just done a 70cc upgrade on my Agility 50 RS 2 stroke. Mollosi kit.
I notice there is quite a lot of side movement of the piston. That not the problem, it will centre in the barrel.
I also see that the small end bearing is moving in the con rod, it moves out of the con rod on the gudgeon pin inside the piston.
The question is. Will the small end centre in the con rod when the bike runs.
Second. It has an 82 main jet, the plug is black on the 50cc. What do people suggest for an upgrade on the 70cc.
Thanks in advance.
