hey Guys, Dave from OK here. Really hoping I can get some help as right now I’m hundreds of dollars in the hole on a really pretty brick.
Bought a bullet train and a handful of parts from bikeberry. Instant regret. But I figured I could make the hardware work. Since the build was complete it’s been **** to get it to start with either the electric or pull starts.
Intermittently, the engine will rev up just a bit and if I’m really careful I can get it to start. Once it does start it actually runs great, for the most part. It feels like it’s trying to give out more power than it’s actually able, like something is very wrong somewhere. Sometimes during operation, especially when going downhill, the engine will randomly stop and sputter out of life. When this happens it takes about an hour or so and it’ll start up with about the same amount of work as before.
I’ve tested, cleaned, and gapped multiple spark plugs. Pulling out the spark plug and testing on the engine reveals it sparks perfectly fine, but it SOUNDS like the problem when trying to get it to start is that there’s no spark. Not sure how to describe this.
Also checked for fuel flow and installed two carbs - one, the stock NT it came with and a “hi-performance” carb I bought as well. That thing is just a piece of trash.
As a bike it works fine but I cannot get it to start without putting way too much effort in. Plz halp. And thank you.
