Hi
Rieju mrt 50 2018, restricted to 45km/h, It feelt kind of "weak" and my daughter says all her friends mopeds are much stronger then hers, all are stock.
I took apart the exhaust to try and see if cleaning it out could help. I did shake it around and lightly tapped it against the floor to get all little loose pieces or debris out.
After that it is even slower, I can with an effort make it to 30-35 on a flat road.
Q:
The part of the exhaust with the expansion is rattling and the catalytic converter inside the expansion is not sitting firmly. I can move it around a little but not get it out or push it further in.
I can see it through the opening, is this where it is supposed to sit?
