Yes, that is what you need to run until the motor is broken in. After that you can change ratios if you would like. Well, actually you will have to, 24:1 is way to rich for a broken in motor.
I'm not afraid to jet And yes, the stock silencers will work with some modification (several members here used them with their aftermarket pipes to have spark arrestors). I know that I should get the pipes and the silencers, but I'm not made of money
OK, let me re-word it. If I put on Aftermarket pipes, and used the stock silcners, would 8 sizes on the mains and 2 sizes on the pilot be good or would I have to go like lets say 7 sizes on the mains or what?
