I rode my bike into work this evening and after work the engine would crank but not start.  So, unfortunately I had to leave her in that parking lot - until I can fix the problem, or get my friend to lend me his pickup - whichever happens first.  

The last two weeks it has been very difficult to start my bike:  I would have to prime it for about 30 seconds, then let it sit for like five minutes and then it would finally start w/ the choke on.   I would have to go through this routine almost everytime.  

I had the carbs cleaned by an authorized Suzuki Dealer 4 weeks ago.  I replaced the battery and spark plugs 2 weeks ago.  It has plenty of gas in the tank.

Anybody have any idea what the problem is?    I want to get my bike home tonight...

Sorry man ... I can't think of many quick fixes that you can do in the middle of the night in a parking lot.  

If we assume (yes, I know that's dangerous   ) that the fuel delivery system is OK, and that the battery and plugs are OK, then all I can think of is bad electrical connections.  The starter motor is getting juice, but maybe there's a problem with the wiring to the ignition unit or the coils.

For starters (ha ha) I would see if getting a jump from a car battery will let the bike start.  The higher available voltage / amperage might be able to "push through" corroded or loose connections.  :dunno:   Once you have the bike home you could break out a meter and walk through the wiring diagram, etc.

Good Luck ....

spark plugs tight?  that'd be my first guess.

You had the carbs cleaned by the suzuki dealer 4 weeks ago.
This problem did not happen until after you took it to the dealer.
I bet you they didn't do something right.  There is something going on with your carbs if you have to prime it to start it.  Gas is not getting where it needs to go.  You need to personally go in there and make sure all the hoses are going where they need to go and aren't F'ing up the vacuum somehow.  If all that checks out then you need to make sure they actually cleaned it and didn't just look at it and say "looks clean to me, Jim Bob."  Put in some 40 pilots while you are at it (if you have an E).  The best way, IMHO, to clean the carbs is to rejet them and kill two birds with a friggin hand grenade.

Hehe... I bet they do that sh** all the time too Errrrr  :guns:

thanks for feedback,

I popped off the seat, panels, and tank today in an effort to rebuild my carbs and replace the air filter - but It started raining  :x   so I threw the waterproof cover over my bike and took cover...

...until tomorrow

Looks like they cleaned the carbs "the funny way":

Air-compressed gun in hand and simply sprayed air inside the
carb through the air intake. Carb cleaned.
