Ron, is this engine close to race tune out the box?? Man I broke one in tonight for my buddy an it fired right up with a super strong idle. I gave the engine a little input on the box an boy was it responsive.
The B5 is by far the most simple engine I have ever broke in

We are useing Byrons 25%, OD97T plug, and 2013 pipe. This engine is going to be a head turner
