So I replaced the engine last week, and got it all back together fine. It runs fairly well and is rideable, but as you can see in the video it hesitates quite a bit in the low RPMs (around 2-3k). Once it's up to like 5k or so, it seems fine. Obviously though, this causes problems when I first start moving.
Any idea what's causing this? I replaced the air filter and checked all the fuel lines, and didn't find any problems. I'm not sure what else it could be (other than spark plugs), but if anyone has suggestions I'm all ears!
