Got the Mac 4-1 headers and muffler on.
This is typically something I do with an extra set of hands, but it went fairly smoothly. Earlier, I had a friend check out the Kerkers and he thinks he can heat bend to fit if using the spin-on oil filter. I let him take the headers and the spin-on. Nothing to lose.
I re-checked the valves - a bit nervous about bending a valve stem. Clearances were OK. .004 for intake and .005 for exhaust.
There is a fuel leal at the petcock outlet which I mitigated, but not eliminated, by tightening the hose clamp. Slowed down enough to attempt to start the engine.
Battery voltage was only 12.05v. Brand new battery (sitting on a shelf though since about September) but probably it ran down when I was dealing with the m-unit quirks. Thanks again, Cal, for solving that issue.
So I swiped the m-lock sensor and hit the start button. The engine turned over nicely for about 3 - 4 seconds, but then the m-unit turned off. Tried again by swiping the sensor to switch on; it turned over .... but the m-unit turned off again after about 2 seconds. Third time, swipe the sensor, and barely turned over before the m-unit shut down. I need to ask Cal, but the m-unit may be designed to shut down when attempting to start with insufficient cranking voltage. I just don't know enough about its features. I hope the Dyna 2000 is somehow not interfering with the m-unit. I will say that during the three attempts to start, there was no sound of any combustion....propbably not enough fuel getting into the cylinders from the carbs, but I did hear gas trickle down into the float bowls.
Battery is on the charger now, and after only a minute or two, the voltage climbed to 12.47.
So, it was a no-go for today.
