I have no solution for the header pipe joint, but will point out we used to find pressurization leaks i aircraft with cigarrettes prior to no smoking rules. Never thought of using incense! Great tip.
Does the Dyna
3000 or speedstar go on the front of the battery box housing like the stock IM? I know it is not that hard to get out, but it is kind of a rat's nest! I installed a 2005 IM on my '03, and really am satisfied with the additional 500 RPM
. I understand a tailored ignition curve could yield more, but hey, I'm cheap!
