Ok, so far I have ordered my engine and my bike and waiting on them to arrive. So now I need to ask some more questions. 1: Can i use amsoil to start and break in my engine? 100:1 seems a bit lean. Not sure just dont want to burn up the engine. 2: What and were can I get a better air intake for this engine (70cc). 3: Where can i get a 415 chain breaker? 4: Is there anyone here who can make a really good muffer if I supply the parts or money? 5: Also; where can i get the stronger wheel rims for front and back? Cant think of anymore questions atm will add more later.
