2003 Cannondale Cannibal/need help

Recommended Posts

I have an 03 cannondale cannible. I picked it up at an auction not running. I have replaced the injectors, fuelpump, fuel filters, fuel reg. and have had the ecu tested. I can only get it to start once in a while and only if i put a fresh plug in. When it runs it pushes oil through the breather tube that runs from the frame to the air box. Could it need a valve adj. and if so, how do you do it. Or does anyone else have any suggestions to try.

Sounds like you are pushing air/fuel into the crankcase because your piston/rings aren't holding compression. Common problem with high performance 4-strokes. My LT-R is starting to do the same thing. I suppose bad valve guide/seals could cause the same problem. Check the oil and see if it smells like gas.

I agree with DD, is that plug oil fouled? You mentioned that you need to replace it to start it. Have you done a compression test?

thanks for the suggestions, i dont think its rings because its not coming from the crank case, it is coming from the frame. the frame also acts as a oil case for diff. parts of the motor.

It will still get pressurized along with the crank case, it is directly connected to the crankcase, the breather tube that comes out of the frame is what is supposed to regulate crankcase pressure. When a piston/rings or valve guides/seals get worn, compression leaks by and over pressurizes the crankcase and pushes oil out of the breather. This will also happen if you have too much oil in the machine.

I have a 2004 ATK 450. Basically the same. There is design flaws galore with these bikes. There was an update for a hose allows the frame rails(oil reservoir) to breath properly. Its a mess. I talked to a genlteman named BRAD about several issues. There is more to come. He was with BlackWidow ATV. They purchased alot of the ATK and cannondale inventory. Now, do you still own it? Also look into Highland cyles. US Highland They are using alot of cannondale and ATK frames.

I know this is way off topic here, but I think this thread may be dead anyway. You say you have talked to someone from Black Widow ATV. I have heard legend of a counterballaned 625cc two stroke motor made by the folks at Black Widow called the "Red Head". I have always wondered if it were true. I have a picture of said motor, and as you can see, it appears to be in a Cannondale frame.

Have you tried contacting Blackwidow atv in Utah? There is also another guy out of Washington state that has helped me. He has all the updates for fuel and oil lines, and everything else you need for your cannondale. PM me and I'll be glad to pass on his info.

I did try calling them once, I left a message, but never got a call back. I am sure there aren't any of those motors around that I could get my hands on anyhow. It was just curious to know if you have ever heard of that motor?

Looks like your throwing parts at it instead of basic diagnostics. Fuel pumps ,injectors and regulators are highly reliable and rarely if ever fail.

Oil pumping out the breather is an indication that your scavange pump is not working. The oil is being pushed out the crankcase from the breather system. Thats also the reason your fouling plugs as its going through the rings.

The engine needs what ALL cannondales need and that is a basic rebuild by someone who knows the basic updates or willing to learn. Its not hard and doesnt cost a lot but it has to be done. After being done they should have as long and reliable life as any other sport quad.

      hi folks - Today I installed a new starter for my 2001 big bear. 400  The old starter has been dead for several years but I'm just too old now to be yanking that pull cord any more.  
      Here's my issue:   When I pushed the start button the starter turned over ... and kept going - even after the start button was let go.  After 20 seconds or so the starter finally stopped .  I pushed the start again and the same thing happened ... In fact, it kept trying to start the machine even after I turned off the key!  (for about 10 seconds).  (I also noticed that the positive side of the battery got very hot to the touch.)
      Any ideas on what's happening?  thanks

      Hey folks, thanks for the add.  I purchased a 2000 kodiak a few days ago.  The seller claimed an electrical problem which he didnt care to investigate.  I thought it was going to be easy...and initially i found a blown 10 amp ignition fuse, and a blown headlight fuse... changed them and tried to start, but when I turned the key to run, the N light came on for an instant and the fuse popped...I unplugged all other connections to the wiring harness I could find, kept the ignition harness hooked up and tried again...the fuse blew again...I then disconnected the outgoing harness from the CDI and this time the with the switch turned the neutral light comes on and I can enable the start switch and hit the starter button and the motor turns but does not actually start, i can also turn on the headlights and taillight in this configuration, however, when i hook up the out going side of the CDI, and turn the key, the fuse blows....HELP?  any ideas to get her running?  I have not removed the gas tank to look under it for frayed wires, but so far, no frayed wired.  With the input side of the CDI plugged in, and all other wiring harnessed connected the starter will turn, but engine wont turn over.  As soon as I plug in the outgoing (8 plug) harness into the CDI and turn the key, the fuse blows.   Thanks!  Gramps

      So I bought a 2001 Quad Runner 250 for my son/wife. Sorry I run a Grizzly 660.
      I’ve rode it many times with no issue.
      My son’s first time out, I could always hear him but feeling he ran it red line in first gear a lot.
      So this is what it was doing during/end of the 2-3 hour ride:
      - halfway though noticed smoke (oil) coming from front of the motor sort of under exhaust manifold. Once back at the truck, it was really noticeable. Definitely oil burning off. I’m thinking from the top end maybe.
      So quick inspection:
      - No leaks or seepage of oil that I could see
      - I pulled the plug and it’s black but not wet
      - No blue/white smoke in exhaust
      - seems to still ride fine
      - Engine still has plenty of oil
      But now that I’m looking at it back at the house - it’s a hard/won’t start when hot. It starts right up cold no problem but once it stalls when hot, have to let it sit for 10-15 before it will start again.
      It wasn’t idling before that trip so I jacked up the idle a bit as well but I think that’s a carb clean/adjustment but...
      Any input is appreciated.
      Thanks for any help.

      Outside of ebay, have you ever been to an ATV auction? Sometimes there are towns, cities, counties, and states that auction off their atvs, stolen, recovered, repos and other atvs, utvs, side by sides. There are also online auctions all over the place. Just looking to see if anyone has gotten a good deal on something or has an auction they frequent.

      I have a 2003 LTZ 400 that i bought a few days ago. The quad was running fine until last night. I let my brother ride it down the street and back and i didnt notice anything etong with bike. Then my neighbors friend came over and said "can i ride it?" I said "sure" so he ripped it down the road all fine and when he got back it died right in front of us. My brother said it was dieing on him also. He also said that he wasnt using the clutch to shift. I told him he was an idiot. Im throwing that in there incase that caused a problem as well. But today i go to check it to make sure its getting fuel which it is and replaced the spark plug incase it wasnt getting spark but it is. So i started it and it was having a problem starting then i got started and was reving at idle high. So i took it around the block and it died on me a little bit down, so i try to restart it and it started so i kicked it into 1st and it kinda launched on me and started going with the clutch all the way in. Then it died right after and wasnt running right during that process and was idleing all over the place and just died and now i cant get it started it again. Before it would start without the choke or priming it. It would start real quick now i cant figure if it needs to be rejetted or something else. Air filter looks clean also. But any help would be gratelly appreciated!

      Hi Folks;
      Has anybody on here installed a winch on a 2003 Magnum 2x4? I am using a Cycle Country adapter plate (only one I could find), but am having a bit of trouble getting it all to fit properly, and am looking for someone that may have done this install and/or may have some pics of the installation.
      Thanks!

      Hello, well back to where I was last year with this carb. Took my 250 to the mountains for the first time this year and blue smoke, too much gas again. I can't believe that this carb gives me this much trouble. Seems like the choke is stuck but the cable moves freely. Anyone else ever experience this issue? Do you think a new choke cable would maybe resolve this?http://www.quadcrazy.com/atvforum/images/smilies/arghh.gif
      OK it was the choke. Put on all new cable and plunger and she is running 100% again. So now the question is, is the carb getting worn out where the plunger needle goes in the small hole and when I use the choke the needle end doesn't get lined back up with the hole?? We'll see how it runs and now that I know what the issue is I can always pull the choke plunger out and reinstall if I start having this issue again.

      looking for direct shift shifting lever that properly fits my 2003 Yamaha warrior 350 and fits my foot the same as a stock 2003 Yamaha warrior 350 shifting lever fits my foot
    • By Wonderwoman
      I am about at my wits end. Took the 250 back to the dealer repair shop AGAIN. Had it in there two months ago for a bad smoking issue. I thought it was to much fuel and washing the oil off the cylinder and burning it. They said it was the head. So I purchased new valves, valve guides, oil seals and had the head professionally done. So $225 later I had a great looking head. Well while I had the ATV apart this far I also got new rings for the piston. Mic'd everything out and everything was in spec. Put it back together and seemed like it smoked a little at the house (5000 feet above sea level). Took it to the mountains (9000 feet above seal level) for Sept. bear hunting and couldn't use it. Smoked worse than before and couldn't run it past half throttle or it would flood itself out. So brought it back home and it is back at the shop again. I say it is something in the carb that isn't set right or wrong jet????????? Anyone have any other ideas that it could be?
