Unhappy HELP!! Bike Won't Start #$^@*~%!

HELP!!

The bike ran well for 2 rides. Now it won't start.

I started it up today as usual but it idled very weak and rough. There was a strong smell of gas. Even with the choke on I had to rev the throttle to keep it going. After about 45 seconds it stopped running. I started it again and it idled weakly for about 15 seconds then died again. Now when I press the starter button in cranks over very strongly but won't start.

WTF!? This bike is beginning to wear me down

What and how should I diagnose? Please help before I push it off a cliff!!!!

1st. pull your plugs and check for fouling, if wet then replace and clean your carbs. Other suggestions sure to fallow.

Peace

It does sound like maybe the floats are stuck - the carbs are drowning and sputtering out. By any chance, did you put fuel in *after* your most recent ride? There's so much garbage in the gas anymore that you may have picked up some gunk that's jamming the flow. Try a little Seafoam, and if that doesn't work, I second wkrizan on cleaning the carbs. Again, though, someone else may have a suggestion that doesn't involve pulling the carbs...

Damn.... I keep forgetting that not everyone has done an ear shave. I can pull and clean my carbs and have them back on the bike faster now than running to the store for a can of Sea Foam...LOL

Does pecking on these carbs sometimes free a stuck float like it did on our old cages...??? Would that be a cheap try...???

I think some have tried that (pecking). You can also get some carb cleaner (with one of those straws) and shoot it up through the drain plug on each carb - that may be enough to work something loose.

I did not know there were cliffs in Florida, did you install the gremlin bell????

As mentioned it could be a stuck float or debris in the float valve or a break down in the ignition system. I will call you on the Bat phone.

Have a look at posts #3 and #5 on this thread.

Two good ways to clean the carbs without having to pull them. I've used these methods twice since my carb overhaul and it's worked just fine.

Wkrizan, Cindy, Old Dog, Doug, Lance --

Thanx for each of your responses! Lance and I discussed your ideas on the bat phone and I will be trying some of your tips:
* bad gas
* fouled plugs
* stuck float
* use less choke
* vacuum diaphram--check vacuum hoses for fuel
* install Doug's Gremlin Bell!

The dealership cleaned the carbs recently (about 300 miles ago) and the bike has been running very well. So, I'm hoping it's not the carbs!

No, there are no cliffs in Florida . . . but there is a VERY high Skyway bridge not too far from me.

I'll let you all know how it goes.

Many Thanx to all!!

Been on that sucker many times! Certainly tall enough to do the trick! Take some ramps to get it over the guard rail! Then smile while you watch it faaaaaaaaaaaaalllllllllllllll!

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!
