I'm a complete newbie at motorcycle. I took the challenge of customizing a motorcycle. Took me exactly 12 months. I got everything to work, Exempt when I test drive it, it seems like its losing power and when I change gears it loose more power.




Here is what I already did:
- I got a mechanic to do a sonic cleaning on the carb.
- Replaced all the spark plugs
- Checked all the Spark plug cables

All the coils and all 4 cylinders work. When the motorcycle is on, I get all 4 pipes hot.
I don't know if it's the carb that needs to be set correctly (Pilot jets etc) or if it's the coils. Is it possible that I have two cylinders not working?

Here is a link to a video I recorded:
