Re: Looking for help!
First welcome to the forum, in my opinion you probably need to get the engine broken in first. About three full tanks of fuel should be good. A free flowing exhaust helps the most on just about everyones build, a modified stock pipe helps with a SBP expansion chamber being better. Some members have built custom chambers taylored to their engine that maximizes the power delivered. A nice replacement air filter might not help performance but do a better job than the stock filter, I have a SBP filter that I like a lot.
Your results may not be the same,Greg
