good day everyone, recently I have been having inconsistent speed issues. at full throttle, with a sbp expansion chamber, I sometimes get 65km/hr and sometimes get only 50km/hr. I am not sure what is causing but the first trip I get better speed e.g. if I am going somewhere I get the better speed and when I get on the bike again after a little bit of time the speed suffers.
Any help would be greatly appreciate. Please keep in mind I am no experienced motorized bicycle so a little detail help a lot.
Regards
