I am currently running the Trail Bikes 143cc big bore with the Trail Bikes 143cc V2 race head and the race cam that come in the V2 head. I am running the stock pipe/muffler because I want to keep the bike quiet. I tried an intake, but I actually lost low end power and had no gains on the top end, so I put the stock airbox back on. I have the Bazzaz and my mechanic that helped install the kit tuned it for me with his Bazzaz self mapper. This is what my map looks like after he accepted the recommended settings. Any suggestions I can make to the map to improve power? I have the software on my computer, I just don't own the self mapping tool yet.
