Ok after getting a legit race race under my belt I’m completely convinced there’s something seriously up with this bike?  Every other 125 out there no matter what age, color or how clapped out was pulling me on every uphill by a lot. If there was a jump right out of a turn, forget about it…
It seems to run well but it seriously feels like there’s an 80cc motor in a 125 frame?
The first moto I was riding so far over my head just trying to make it go that I ended up laying at the bottom of a downhill dizzy with some bruised ribs and a sore ego. 2nd moto I just rode the best I could with the damn thing.
I have no idea but I’m in need of a local So-Cal air cooled 2stroke guru. 
Anyone?
