Murphy's law in full effect Bike simply wont start
« on: June 19, 2018, 11:14:00 am »
I have tried everything possible and it seems like murphy's law is in full effect.  Bike has a strong crank, has gas, battery is new, I do have strong spark; i even changed the ignition coil and nothing seems out of place.  there is fuel delivery with petcock open in the normal position and have even tried with petcock in prime position, Tried even with clutch engaged (holding clutch leaver) for the life of me i want to still say fuel delivery issue. I know fuel delivery is present when i remove my individual air filter (number 1 cylinder) and you crank the engine there is suction and if you cover by hand the hand had fuel on it.  HELP >:( >:( :truce: :truce:

Sounds like something is jammed up in the carbs. Have you opened the drains to see what comes out? Maybe old fuel? Maybe its all gummed up in there. That's my bet. You may try starting it with some starter fluid just to see if the mechanics of it all work out, but my money is on that carb.

have there not been issues with  the crank sensor getting out of alignment putting spark out of degree order?  left side crank case - people inadvertently rotate the crank with the obvious nut but that can rotate the sensor?

did you just set the valves using that rotation method?

I do it that way to but am very cautious of the way I do it.

My guess, if there is no pop or any indication of ignition with the starting fluid then
you might look at the valves. If there is some indication of fire, then I would look at
fuel. Did or was the bike ever run in you presents? Is it possible you reversed the
wires to the coils? Clymer manual shows green wire to the right coil negative, black
wire to the left coil negative. Left coil to spark plug 1 & 4, right to the rest.

Do you smell raw gas coming from the mufflers right after cranking? If not I also think you may need to check valve clearances.

Vacuum hoses/caps in place on the throttle bodies?

MOB strongly recommends against using starter fluid as it will damage the rubber diaphragms in the carbs.

Backfire tells you you have a spark, OK. It does not tell you about spark timing
or cam timing. If when it cranks it seems normal you have some compression. At
least you should be getting some fire. (MOB is right about starter fluid, don't go
over board with it) could you double check the primary wiring at the coils, black
wire is on the left coil, fires 1 & 4. Green is on the right coil firing 2 & 3.

When my pulse coils went it started as an intermittent shutoff, but it then devolved into no starting and backfiring while trying.  It was a very frustrating issue on a bike with freshly rebuilt carbs that I knew ran well.

I'm with Harry.  Try another set of good spark plugs.

I'm just watching this time....curious myself about the missing clues....

(like after following a time line of posts, when, if ever, did this bike in it's configuration, ever RUN...? )

This . . .

Did or was the bike ever run in you presents?

and This . . .

when, if ever, did this bike in it's configuration, ever RUN...? )[/size]

Can you confirm if this bike ran before?

if YES:  What has happened between then and now?  Don't leave anything out.

If NO:  More wild cards to consider.

individual carb filters = doomed from the git-go.  :-[

 do a compression check when you remove the plugs for inspection.

Following MOB's post I too went back and looked at historical posts.  Hmmm!  A Sandy survivor.  It has been a long time and flood damage can cause every form of electrical and mechanical issue.  Also appears to already have new plugs.  Hmmm again.

yes do smell  gas and 2 backfies

Did you recently remove and change the plugs or plug wires?
Might be possible that you have the spark plug wires on the wrong spark plugs.

it really, really, really helps, to go back in a thread, and read it completely, all the back and forth stuff... before asking the same question again...
(and as I suggested, go back and read everything the O/P posted since day one, about this bike, in all his different threads...)

Luv ya bro, but this bike has some issues that without actually having it in front of you, and being able to spend about 40 minutes going down the list of things in a logical manner, like it should, this is all a shotgun blast, without having a target in sight.
The list of deviated and different parts installed, and history on this machine ( as it sits right now) is so huge, that "simple" stuff ain't simple now.

I just read all the other threads on this bike. "some issues" would be an understatment.  :rotflmao:

Is the bike really worth fixing? For me, fire + flood = shot.
For me that means, all new wire harnesses and electronic assemblies, all new rubber, all new seals, bearings, gaskets, and other stuff I can't think of at the moment.

I can't even imagine individual air filters for the carbs.
We may never see the end to the questions.

MOB is right. We need to see the bike.
