Alright. What do you mean they're a bastard carb though?
I'm not sure what kind of porting. Last time I seen it was right after I got the bike and pulled the motor to repair a crank seal, and honestly at the time I didn't know what I was looking at, but I could tell it was definitely cleaned up.
Riding…
Mostly trail -->mid/high rpm...
… some pit riding where I keep it pinned. I try to keep it pinned as much as possible but my riding conditions/spots don't always allow me to.
I would love some more mid range power without sacrificing top end. Top end is what I love about this bike of course.
I have no idea honestly. I bought the bike like this.
