Honda Express moped - loosing performance all of a sudden at high speeds (high rpm's). What's going on???
So, recently I neglected to check my nc50 express moped oil level and I came close to running out completely. I luckily checked before it was too late. Had I waited too long, the honda engine would have eventually seized. Side Note: You can check the oil level using a little see-through window in the gasoline/oil tank on the back of the honda express. [see diagram]
So I filled up all the oil reservoir with new Lucas Semi-Synthetic 2-Cycle Racing Oil. I then rode my Honda noped to work and 5+ miles into my ride, I noticed poor performance at high rates of speed. Just a few days ago I didn't have any trouble going 30+mph on the moped, but now I can't get over 25 mph. My honda express moped top speed totally decreased and isn't changing. I can also feel the engine "pulling back" or lacking power at the top honda speed ranges. It has no problem accelerating though.
After doing research online I have found many fellow moped riders LOVE synthetic 2-Cycle oil. In particular, I discovered many riders stand by AMSOIL DOMINATOR® Synthetic 2-Cycle Racing Oil (TDR). Perhaps I should give this a shot. Maybe my Lucas oil just isn't cutting it.
I will continue to repair my problem and post my results here. Perhaps a video on how to remove the Honda Express Engine Oil Pump??? We shall see... stay tuned and check back often for new posts.
