Title: Start of a bad day. Wont Start
Post by Arnold on 06/15/11 at 07:14:03

Hey guys,

Seemed like a nice day out so got on the bike, wont start...

Was running fine a few days ago, starter kicks in, I dont think the engine does. Every so often I get a puff of smoke out of the air filter but engine wont start. I probably drained the battery by now. Didnt have time to mess with it this morning so I took the car. Anyway, where do I start?

I am sure that others, far more knowledgable than I am, will chime in.  First thing is to charge the battery, that is an important part every time you hit the switch.

Yea, it was raining pretty hard a few days back, the bike is outside but covered. Who knows if some humidity got in there somehow. The only thing I did different is I have a raptor petcock and I left it ON and usually turned it OFF. Maybe it's flooded. Smoke would mean I have some kind of spark though.

Maybe the rain had somnething to do with it, moisture will do funny things.  I have the raptor and never turn it off and have never had a problem.

If these things arent starting, step one is to make sure the battery is HOT,,

Yea, first thing I noticed was I left in ON but there was no gas smell and no puddle. I think I can rule out the petcock. Unfortunately I had to get to work and couldnt troubleshoot. now it's gonna bother me all day.

When I get home tonight I'll try to pop start it in 2nd, I live on a slight hill so that's easy to do.

Hot you mean full charge?

Someone will correct me if I'm wrong but there is no harm in leaving a raptor petcock turned to "ON" unless you have a bad float.

Yes,, stolen batteries have no greater cranking power..

Oh good :)

Yea, leaving petcock ON shouldnt be a problem, I dont think that's it. I turned it off now, hoping that if anything got flooded it will dry by the time I get home tonight.

Like precher and justin said, HOT battery. Electronics don't work well with reduced voltage. When I have a no start on almost anything that requires gas and the engine is turning over I put a SMALL squirt of starting fluid in the airbox/filter and give it a try. If it cranks and dies it is usually a gas problem or a bad plug. If it doesn't do anything I then move to check for spark at the plug. Starting fluid is dangerous and should be used with caution to protect you and your engine. About the float--the float does just that. When the carb bowl is full the float rises and pushes on a needle valve to cut off or reduce flow of gas. When the engine is off the level in the bowl is steady and full. If it sticks or even has a hole so it sinks, gas will run whereever it can because of a wide open condition of the needle. It can, but does not always, run into the engine case and reduce the lubrication of your oil. Check your oil and give a little sniff test at the fill hole if you think it has gas in it. This is not a complete list of things to do, but they are first on my list. Others do it differently and can tell you their ideas. But first, as others say, charge the battery with a good charger, not a trickle charger. They take too long. Take 12 volts and call me in the morning. ;)

Yea, I got a charger. I'll see if it pop starts, that will rule out the battery and starter. Wonder why I got smoke coming out of airfilter though.

Well, got home, tried to start the bike normally and guess what? Started right up, runs fine and started up again. Who knows??? Humidity? Flooded? Electrical short?....

Maybe your bike is just not a morning "person"  ;D

Id lean toward flooded..
I know if I twist the grip on mine,, Its over..

Took it to work this morning, no problem. I'll never know what happened. I turned the petcock off this time though.

I love it when things heal themselves.  Sometimes it works for me, but then I wonder what happened and and paranoid for awhile. But I am alwaya glad when it happens.  Even a blind sow finds an acorn once in a while. :D

I know right, I took it to work and I'll be freaking out all day until I know it starts tonight :)

Im no expert on bikes but I have had the same type of scenario with many vehicles

I'm gonna say one or a combination of 2-----

1 Dampness had an effect on SOMETHING electrical

2 You flooded it

or combo, dampness caused the problem THEN you flooded it trying to start.

Unless a vehicle needs the throttle thrown to it by nature to start (not good on anything) or its cold.......I rarely try to start anything by giving it throttle.   I have some old cold natured atv's, honda 3 wheeler and honda 4 wheeler.
I hit the start button for a couple of sec's with no choke, then close the choke up and crank till she fires.

Throwing fuel in rarely helps, IF you did that.  Also, a puff of smoke (sometimes vaporized fuel) thru the air filter tells me she might have had too much fuel in it.  

Make a notation of damp weather on your calendar of it.   see if you have the problem next time its wet.  Sometimes it is hard to see a dampness/electrical problem, I have seen many a hairline crack in something cause terrible starting issues.   BTW, the roll start will help with electrical issue diagnosis, provided you haven't flooded.

Good luck and God bless you,

Farmer

The only difference between the morning where it didnt start and the evening when it started was I turned the petcock OFF all day. I never give it gas to start it and it never needs the choke when it's above 40f out. I did have some weird electric problem with this bike in the past though. One relay fried and I've had it once or twice where you turn the key and nothing happens, no light nothing. I must have a crappy connection somewhere.

Any day the bike won't start and take me to work is a good day   8-)

Post by VAFarmer on 06/16/11 at 08:06:15

Hmmm........

Bad petcock possibly?

Don't have a solid answer for testing one of these, as I have never looked at mine.
Leave it on all night the next time you DON'T have to ride to work in the am, and before you leave see if the bike fires up, or floods.
Guess the petcock COULD be dumping too much fuel...but wouldn't you experience a totally different running experience thru the operation?
I DON'T think it would have been battery related, as it did have enough juice to fire it that evening, right?  Riding far enough to work to charge it?  And still have enough juice to "fire right up" that afternoon?  could be possible, but unlikey.   When a battery starts to go, it will go down after a night or two. Check your date on the battery.
Leave it set for a couple nights with petcock on.  Try to start a couple mornings later when dry (if possible).   That might be enough evidence for me to say--Battery is probably ok, petcock probably not a problem.
If it rides good for a week or so after that, and no rain---then wait until dry day again, start it up.  After it cools, put your garden hose on MIST and spray the bike down well.   See if you have any problems starting then.
So many things it coulda been.....
Ignition switch might have an issue
Petcock
Moisture
Electrical system (lots right there)
Water in fuel
Trash in carb
Compression fluke
You get the idea.   I'd just start making good notes of what you have tested to your satisfaction, so you can kinda rule that out.
You know, basic mechanical stuff that we all forget when faced with a problem on our OWN bike.  ;)
Remember, fuel-air-fire-compression
Fire and compression are the hardest to test for, IMO.

Hate working on those ole' diesel farm tractors.......ugh.

Good luck and be blessed,

Farmer

Yea, looks like the battery recouped enough charge during the day, fired right up and got a puzzled look on my face. I'm glad it's not compression issue for sure. Keeping my fingers crossed for tonight.
