So, I sort of fucked up. Yesterday a buddy of mine started doing power wheelies and sort of taught me how to do them. So me being me decided to give it a go. I was sort of doing it successfully but I stayed in first gear while going 50-60 attempting to do them for a few hours. I’m just telling you guys this because I assume this is where the problem originated from.Today as I’m riding I get on the highway and for some reason the bike I managed to hit 170 on was struggling to go past 100. I’d start pulling back on the throttle and the bike would stop taking it and damn near throw me forward. Then once I got off the highway I passed under this bridge going home so I decided to give it a rev as I normally would and it wouldn’t go pass 9-10k rpm. I’m a pretty new rider so I have no idea what I should even be trying to fix on the bike.
