So today was an exciting day cuz i wanted to try out my new spark plug since i figured my last one would not give me enough power to start my bike. it is a ngk bp6hs? obviously this spark plug has a huge top that the boot will not fit on so i think i will swap it out for an automotive boot later on. so i reswapped the plug and the bike starts fine, weird since i had trouble starting the bike yesterday with about same weather temp almost. While testing the bike out around the neighborhood, the bike would jus not go like it used to, there is absolutely no power. Power starts to drop even on flat ground which i thought was very strange because i had no problem couple days ago wit the power issue. what do you think could be the issue with no power? idling is fine, just when it starts to move. I switched the c clip from rich to lean and then back to the middle where i had a tan spark plug from before. This is starting to get frustrating. i was hoping to be enjoying this bike this summer but this chinese girl is giving me to many problems. Already got another new 2 stroke motor on the way and if this one craps on me im gonna forget about these motorized bicycles and move up to buying a motorcycle. Already invested around $600 into this to include the bike.
