Starting problem

[HuskerChop]

This is good cr, front, actuated, very short travel and cut down part of shaft allows compression to pass thru plunger seat, thru inside of cr and exit thru holes

Here is pic of good cr from prvious post. Dont quite have this posting pics thing fig'd out.

Again, rear cr, notice how large diameter of shaft is blocking the bleed holes of cr that bleed off compression into exhaust port

I see what you are talking about. I am new to the V twin thing and forget about the cylinder being sparked during the power or exhaust stroke. Lesson learned,thanks.

Now another stupid question, I therory shouldn't the engine stop with one cylinder close to the top of the compression stroke? Of course I realize that the compression could be lost between starts.

I used to have trucks with 2 stroke detroit diesels in them. They were know to roll over and start running backwards especially on cold mornings with weak batteries and a good snort of starting fluid.

The poster and Sven are obviously better mechanics than I am. But I figured I'd throw this out to make sure you thought of it. Not sure what bike you got didn't see it posted I'm guessing its +05 since its a crank sensor? That should be a single fire coil and ignition box. Shouldn't fire on both strokes.

That does happen on EVOs with dual fire coils and ign boxes and that is stock on 04 and earlier BDM.

Just wondering If you got a mismatch between coil and ign box causing issues.

Theinfamous, you are correct, this is a single fire ignition. One cyl at a time. Also a single fire coil installed. The problem happened same time the first Thunderheart adj ign crapped on me. Been problem since. When the ign failed, coincidence obviously, i am guessing the cr failed as well. When the ignition would cutoff, the cyl would still fill as normal cuz was at highway speeds. Ign would kick back on intermittently and would have very large amounts of fuel in exhaust ports n exaust, huge backfires. All happened in split second before i could get clutch in and roll to stop. Was pretty violent back fires. Im not however impressed with Braislle battery. Some people have great luck, some not. Im one of the nots. Just ordered new cr's and a new tomioka 1500 battery. Will post how all goes

And yet another lesson learned. Thanks for the info.

I had a typo last night 2004 and earlier had DUAL fire coils and DUAL fire ignition. I incorrectly said single. I've edited my post.

Re-read it this AM and said "well that didn't make any sense" lol
