Recommended Posts

My 2005 500 TBX 4x4 has only 400 miles on it, and it is down AGAIN!! This time when I start it, fires up, idles fine, warm it up, and get it out of barn, and give it gas, NO POWER!! It starts to back fire, and flat out barly goes over 5mph. Changed the plug, cleaned the carb, but still no good. I hope that someone has had this problem, or can point me in the right direction. The closest dealer is far away, and I dont have 2-3-400.00 dollars to take it to a dealer. If someone has any ideas, or has a question, PLEEAASE let me know. Thanks.

you can either take your gas tank off and empty it in to a pail, or shut the petcock off and remove the fuel that way in a line into a container. the fuel lines will come off by twisting them sideways back and forth as you pull at the ends where they connect. probably there are no clamps holding them on, just friction fit. just blow thru the lines to make sure they are clear and you can use something the same inside diameter to remove any scale.

you might also want to unscrew the petcock and make sure the fuel screen isn't clogged also....

I really appreciate your help, but I don't know what a petcock is. Is there a link, or a website, that explains this, since I don't expect you to sit and try to explain in type. But if there is a link, or you know where this is already explained, that would be a big help. Is the petcock like a fuel shut off valve maybe? I do know where the fuel lines go into the non-electric fuel pump, and there are no clamps there I don't think. I think there is one from the tank, and 2 to the engine, 1 to carb, and one vac. I believe. I have a Artic Cat repair manual, the online version, but there is very limited info on the fuel system, in regards to the fuel pump. Maybe I will try YouTube, and get lucky, unless there is a better site that you know of. Thanks for youre help.

The first problem is that usually some part of the carb was put together wrong, the plug if fouled, or the gas is bad. I usually siphon out the gas from the tank I know 06 and up is not gravity fed by guess is the 05 falls in the same boat so the is no fuel shut off.

Put some new gas in it and run the required mix of sea foam in the gas and let it idle for a while to work its way through the carb then check and clean the plug. At least that is where I would start.

      Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

      I did a compression test on my 2005 Bombardier Traxter 650 CVT and it's 75 PSI.  service manual only talks about leak down test.  No specification for engine compression the manual.  What does 75 PSI tell me?  Thank in advance.
       
      A little history of this machine.  640 miles.  Picked it up about 2 years ago, not running. Probably the computer.  Tested all circuits and confirm it was the computer.  Long story short, I watched a Youtube video and fixed the computer. ATV now started and runs.  BUT, it tops out 20 MPH.  I cleaned the carb 3 times also using a Mikuni carb kit after the second time.  Slide in carb is going up and down.  Only adjustment for fuel is at 1.5 turns out.  NGK Sparkplug had soot on main part but brown on the electrode.  Champion sparkplug is brown.  I check CVT clutches and they both appear to engage like they suppose to.  Checked valve clearance it's 0.00, I can't get any feeler gauges in-between.  I check timing chain I believe it's in the correct position and hasn't skipped.  I removed muffler plug and drilled into muffler to try and make sure it wasn't plugged.

      Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

      2022 Sector 550, 414 miles on it and the gas gauge reads empty.  I topped off the gas and it didn't change.
      There is no fuse that I could find.  No access at the gauge cluster.
      Wiring on the top of the tank looks good, properly connected.
      Could the sending unit in the tank be stuck or broken?
      Has anybody removed the tank lid?  Any tricks?  
      Any other ideas?
      Thanks for any help,
      Clyde
