2006 DRZ 400S dies when I hit the throttle.

Hey Everyone, so I'm needing a few tips. I recently picked up a 2006 DRZ 400S and I'm having some issues with it stalling out (dieing pretty much) every time I give a quick rev of the engine or get on the throttle quickly. I have to rev it up slowly so it doesn't cut off.

OK, so what I know is that it has the 3x3 mod nicely done, DynoJet Stage 1 kit (not sure which jets were used), and the stock exhaust. Any ideas? Is too much fuel being dumped in the carb so it stalls out?

I plan on putting the full Yosh RS-2 exhaust on and either installing the DynoJet Stage 2 or changing to JD. Will this help?

Thanks in advance for they help.

If the fuel mixture screw was not taken out and an extended mixture screw installed, would this be the problem?

      A tiny clear rubber tube on bottom of carb.  On bottom sort of on side, by floats, the other end just hanging down.  Was it always like this? Or does the other end go somewhere?  Today after multiple trys with kick, choke on/off ,,,fuel keeps pouring out the tube.  This bike has always been hard to start.   Thanx  guys!

      New spark plug, new air filter. Went for a ride and all was good. Hadn't run it in a week and a half. Now it won't start. Getting spark. The plug is dry. Is it possible I over oiled the filter and it has somehow gummed up the carb/ float? Thanks

      My 01' yz125 seems to be requiring a large amount of throttle to get off the line. I've ridden plenty of properly jetted 125's and none required quite so much throttle work from a dead stop. Even slipping the clutch it wont get going without a pretty healthy amount of throttle. Thinking it just needs a clutch rebuild kit and maybe a basket. Any info appreciated!
      If it helps any here is what it has done.
      FMF Fatty, VForce 3 reeds, and an iridium plug.

      Hey all, I just bought a street legal 2005 WR250F. Took it out once three weeks ago. Did about 60 miles on the dirt and 15 on the road, bike ran great. I took it out this past Sunday and was about 75 miles into my ride when the battery died. The battery is cheap, but it is brand new and was on a battery maintainer the whole time while it sat in the garage. I kick started it, and it fired right up. I was on the road for about 5-10 miles in fifth gear when I felt the bike slow down a little bit, and I noticed the sound coming from the bike sounded a bit deeper than usual. About a half mile later the bike started to bog down like it was out of gas. I filled the tank back up and experienced the same problem. The bike began to bog down, then puttered out like it was out of gas. Eventually the battery completely died and I was not even able to kick start it. I trailored it home, hooked it up to the maintainer, waited a couple hours, and the bike fired right up with the electric starter and the choke out. However, it was still puttering a lot when it was idling at this time. If anyone knows whats up, I would appreciate any and all help. Thank you. #Yamaha#wr250f

      I’ve got an old barn find ‘83 CR80R that needs either a new carb or a rebuild kit. I haven’t been able to find either anywhere. 
      Does anyone know where I can find either?
      housing, bowl and all the hard parts seem fine, if I can find a rebuild kit with a new float I think I’ll be ok. Right now it runs but only when I leave the choke on, smokes heavily and likes to bog down on takeoff
