Hi. I have a problem rn. My cylinder had a very bad compression, only 4 so i then changed to another 50cc cylinder. I noticed immediately that it went very slow and had really bad acceleration. To fix this lack of speed I pulled out the wedding ring from the variator and then put everything in place. The only problem is that it goes almost as slow as before.
I just want to mention that before the new cylinder it did 56-58 km/h put now it does 52 km/h. I don't think it is the cdi anymore because it actually does 9000 rpm.
EDIT: Do you anything more I can do to make the moped go faster?
It is a TGB Bullet 50 from 2009
Please help.
