Honda express 70cc DR kit, ticking noise
Im new to 2 strokes. I recently picked up a honda express that came with a new DR kit. I installed the kit and put a pz19 carb on it. Ive been using AI to help get me dialed in on jetting. Long story short, i was a bit lean on the top end and took it out for a longer ride without knowing. After maybe 15 min of running in the upper rpm but not flat out, the engine died. It was like I hit the kill switch. I cranked it over right after and the piston moved fine but it wasnt starting. It may have been from an over heated coil and not a seizure. After maybe 5 min of pushing I tried starting it again and it fired up. Now the engine has a ticking noise that changes with rpm. Its not noticeable in the higher range. I got my jetting fixed so Im good now on that.
Im trying to figure out if the ticking noise is a rod bearing or something else. Some basic research suggested it could be the roller bearing in the piston end of the connecting rod. I didn't see any signs of impact on the spark plug so not sure if it might be piston slap. Any thoughts? I can try to post a short video if that will help in identifying the sound.
