2004 Raptor 350 Backfires after carb replacement

Recommended Posts

First of all I would like to thank you everyone in advance for there help.

I picked up a 2004 Raptor 350 for $500. There is less then 50 hours on this machine. Its been sitting for most of its life. Its in pretty decent condition. I pulled the carb and cleaned it out. It was full of green corrosion. While I was doing this I notice that the throttle plate was sticking. I looked to see if parts were available separately and nope they were not. I found a 2006 raptor 350 carb on ebay for $65. I received it today and it was even more corroded then the original. So I took all the bowl internals and swapped them over to the 06 carb. I cleaned everything really good. I slapped it on the bike and it runs but its back firing when you give it gas, doesn't want to idle with no choke. I have to apply the choke perhaps 20~30% to keep it at an high idle so it won't die. My question is. Is the 06 carb compatible with 04? They look identical. My next move is to order a rebuild kit. Do I order one for 06 now? Are 04 through 08 the same?

Check with a shop manual and make sure you have factory jet sizes. Also d/l both year manuals and check part numbers to see if they are the same.

All else fails speak with Rappy he is a Yammy wiz

      I have a 2004 Polaris Trail Boss 330 and I want to eventually fix it up if possible, but the thing is the transmission or Gearbox that allows you to shift into forward and reverse and such isn't connect to the engine at all, it isn't even bolted into the frame. Anyways the Secondary Driven clutch is missing. The ignition was busted so I switched it out and tried to hook up power to it and the lights wouldn't light up and it wouldn't try to let me start it with the electric starter. 
       
      So I bridged the connectors on the starter solenoid and it cranks the motor. I was wondering if anyone knew why the dash lights don't work or any of the buttons. I did find a cable disconnected I have a picture of maybe someone can tell me what it's supposed to be connected to. It has 3 wires going to the connect Green Purple Red. I'll enclose a picture of it and where it is connected on the wiring harness.

      Trying to replace the carburetor on my 2003 Bear Tracker 250. Two brand new carbs in a row from different suppliers.   Both leak fuel out over flow and intake as soon as I turn the gas on. Any ideas. Am I doing something wrong?

      Hello. I am a new member as of today. I had a quick question to ask. I recently was driving mt HONDA RANCHER 2004 GPSscape 400 and my display stopped working. I was driving the atv and all of a sudden the speedometer and the service lights went out. Also the lights stopped working. I am still able to shift gears, change from 2wd to 4wd, and can still select if I want EPS or Auto. I have checked my fuse box and have changed a few of them around. It did not change anything. I was wondering if anyone had any idea of what had happend. Thank you for your time- Trenton

      So i was riding the other day and my quad randomly shut off. It started back up and ran completely fine for a little while and then it started idling terribly.
      I cleaned the carb and changed all the jets and everything except the float due to the rebuild kit not coming with one and it actually runs worse then it did before.
      It will run and idle decent now but when I give it gas it dies.
      Does anybody know what could be wrong?
      I also changed the spark plug and air filter along with the oil and oil filter.

      If we had a dollar for every time the question “Which is really faster, the 700 or the 450?” shows up in our inbox, mailbox, or voicemail, we’d be putting this magazine together from a bungalow on a barely inhabited tropical isle named Quadhama.

      Hi Everyone
      This is my first post and I was wondering if there is anyone who can help me solve a problem I have with my Yamaha Kodiak 400 4x4 Fitted with a Mikuni Carburetor . The year of the quad is around 1998, the reason I am not sure of the date is, there wasn't any paperwork and no details on the frame either.
      The quad had a bad leak from the carb overflow which indicated that the float needle valve was blocked or passing so I replaced this and put everything back together. The quad ran really well until I took it onto some rough ground to have a ride around, a few hours later the engine started to run really rough as if the engine was flooding. I have removed the carb again and cleaned the needle valve out and the whole of the carb just in case there where any dirt behind it. Engine now runs fine again but fuel has started to run out the carb overflow again.
      I have tried everything to try and stop the fuel leaking out the overflow but its still happening. My last thoughts where to adjust the float level and its still happening.
      Has anyone got any thoughts on the problem or could suggest whats causing the fuel leaking out the overflow.
      Thanks for reading
      Kevin
