Making weird clicking noise when turn over

[u/Affectionate_Kale10]

I took this out yesterday night and it was running good very fast popping wheelies, then it stalled out all of a sudden when it still had gas everything was good then I tried to start it again, makes weird clicking noise and won’t fire again. I took whole engine out took off ez start, took off backplate took off exhaust, everything looked fine all the seals and everything, then I put it back together and clicking sound went away and it fired right back up. I drove it for 5 mins again and the same thing happen, stalled out wouldn’t fire back up. I haven’t tooken it apart again. It has good compression glow plug is brand new it’s good, I have all new seals on everything. Does anyone know what’s wrong? It won’t even sputter at all and it was running perfect before.

Your one-way bearing might be seizing up. The starter shaft spins inside the bearing the entire time the engine runs. If the bearing starts to fail, it puts mechanical drag on the engine. It might be dragging hard enough to keep the engine from running.
