I am thinking I do not have any spark? Help!

All, the other morning when I went to start my bike up it cranked and cranked forever, I thought maybe it was just flooded. So I let it sit for a bit and it finally started. Rode it to work that day, it startef fine when I came home. I parked it in the garage and went to start it this morning and get the same thing. It just cranks and cranks, I pulled a plug wire off and held it next to the plug and cranked on it. I did not see a single hint of a spark. Anyone know where I should even begin?

 

It may be one of the "safety" features acting up. Check the side stand wiring/switch.

 

spark can not make that far of a jump from the wire to the engine.
you will need a plug hooked to the wire and touching the engine/frame.

I dont think this is spark related as much as fuel. when it just cranks, what do the plugs look like?
are they wet, dry, etc?
have you tried starting fluid?
what are the voltages on the battery sitting, key on and cranking?

 

u saying that take a plug out keep it connected to lead put on top of enjine then crank it over, mines just died i had spark yesterday, today nowt, my cdi has gone down bugger

 

your side stand cannot be down,it kills the engine ignition. put it on center stand or sit on it and put the side stand up.

 

make sure ithe side stand works as if dirty connections, itll work when it wants to, i took mine of and joined the wires together, ive done it to 4 of my suzukies without any probs, but im not sure on yamahas, ive got to work mine out now, y she wont spark,,,,, joys

 

if the sidestand is down, it wont even allow the engine to crank. So, I am pretty sure that isnt the problem

if it starts with starting fluid, the problem is fuel related, not spark

 

prob dirt in main jets or pipe, or your taps not working,if u get spark,that is, have u trimmed the leads,,,

 

Ok, I took all 4 plugs out, they were all wet. I dried them off and hooked each of them up to a plug and placed it next to the engine. I am getting spark on all 4. I would assume I am getting fuel however I noticed the hoses coming from the petcock to be a little "wet" as well so now I am wondering if I am having petcock problems? Thanks for all the replies.

 

If it is a safety switch. Will it even crank over?

 

no, it wont crank with a safety switch.
if they are wet, you are probably getting too much fuel. I would start with the petcock and then move to the floats.
sounds like something is sticking in your needles.
have you smelled your oil? does it smell like gas? that will tell you if its the fuel seeping in

 

Is it better to get the one that Chacal sells that I can manually turn on and off? I sent him a PM this morning requesting a quote for that.
