Shovelhead Just Will Not Crank

HELP!!! This is for the record books. I have a newly rebuilt shovelhead, 93" S&S Stroker kit, Crane Hi 4 ignition. Ran great for about 3500 miles. Riding down the road about 60 mph and it just quit. Just like you turned the switch off. My mechanic has tried everything, replaced ignition, coil, wires, plugs. It has fire, compression, oil pressure, fuel, it has been timed, but will not crank. Mechanic is at a loss, but thinks something in the engine has spun causing it not to fire at the right time. Can anybody help? Is it something in the engine? Can't be electrical because everything has been replaced. Please help!!:witsend:

You should be able to check the timming,I would think if you have compression your valve timming is correct,You say it won't crank...might want to look at a wireing diaghram to make sure you are getting voltage where needed to roll the motor over.Bound to be some more people to help you out here...Good luck

Yea it is static timed and it does turn over. He had it on a dyno and is showing spark. Everything has power. reading all the right volts in the right places but it will not start. Mechanic says it must be something in the bottom end. Its just crazy and he said he has never had this happen before in his 30 plus years of wrenching. Go figure

Have yo tried changing your fuel,it could be that you have water in your gas. Usually they will spit and sputter first though.

Thanks but my mechanic has tried all of that. Actually installed new electric ignition and even put points back in and tried that also.......still nothing. This has really stumped the band. Says he has tried everything, just don't know what else to do.:rant:

Gas is good, good compression, all electrics OK...................

Could you be 180 deg. out?? If its single-fire,change plug wires around. If you have compression, spark and fuel it should fire up for you.

I dunno, I would think the mechanic would have it right. He did put points back in and it still did not start. I am done with him and going to get the bike back tomorrow and take it somewhere else.

Yea, thats what I thought. I am going to load up the trailer and go get it now. Guess the mechanic doesn't know all he thinks he does. Anyway, thanks everybody for all the suggestions. Ya'll ride safe! Later

next sugestion, try new mechanic

pappycool...Let us know what you find out....Just curious here...The motors are pretty simple...Good luck...

The only thing I can think of that may have spun to put it too far out of time to run is if the cam gear wasn't pressed on the shaft right and it spun on the cam.
:devil:

could your exhaust be plugged up...or the exhaust valves not timmed right....Guess I'm kinda drawing at straws...but it is baffling......

Hey Guys! Well, I am only a shade tree mechanic when it comes to some of this stuff. I personally think it is something simple. Human error, anybody can make a mistake. But I had enough of that mechanic and took it to a HD Dealership. I can;t help but to think it is somehow in the timing. I just don't think he has it timed right for the electronic Ignition. I am like Lucifer, the only other thing would be the shaft spun and got the gears out of time. Maybe sheared the Key or something. That is what the mechanic is thinking. Everything everybody else has mentioned has been checked or done, so says the mechanic. I should know something this week from the HD shop. I will let you all know. All I know is.........I WANT TO RIDE! Thanks for all the help.

Yeah, let us know what you find. I'm kinda surprised you have a HD dealer that will even look at a shovel. Most just give ya a dazed and confused look when you say Shovel
