2013 ('12+) WR450F Would Not Start: Kinked gas line.

6 posts in this topic

So, this cycle and my wrench are still getting aquainted...

 

I had it apart for the initial valve clearance inspection (it passed), and it would not start upon re-assembly.  Cranked and cranked, but no fire.

 

The Fuel Injection system has a long gas line from the tank to the FI intake, and it can rotate on some of the connectors.

 

The fuel line is long so the mechanic can tilt the gas tank up 'n back out of the way during service (its good that way).

 

Problem is, it can "kink" pinch closed if not stuffed back together just the way it came out...

 

You'll hear the pump pressurize the line, but no fuel will get to the FI.

 

Heads up for ya...

I did the same thing after I installed my 3 gal IMS tank. This being my first FI bike I had to scratch my head for a bit before I found the problem. I felt like an idiot once I found it though.

You couldn't have felt dumber than I did recently kicking my bike to death over the course of an hour or so trying to figure out why it wouldn't start when it was running great hours earlier. It wasn't even trying. Started removing stuff to look at the plug, pulled the fuel line off the carb and not a drop of fuel spilled out. Went to reserve, and fuel came pouring out. I didn't realize how far I had burned that tank down. Hooked it back up, added some gas, and big surprise, it started immediately.

Didn't mean to hijack the thread, but it can happen to anybody I guess. The on/off switch still gets me once in awhile, too.

Got my tank IMS on the way.  I had too much "range anxiety" to not get something larger than OEM , and I dont like to carry gas on my back.

Just put one on today. Any idea about "safe" range? I'm thinking maybe 60 miles.

I've been reading your posts, and I think I'm somewhat familiar with your skill level and type of terrain you ride in.

 

I dont know what FI map you'll choose to use, and that makes a big difference too, I believe that choice can swing it +/- 50% difference.

 

But, considering all that, I'm thinking 20 MPG is conservative for you, for your terrain.

 

I notice the "natural" color IMS tank is translucent: I can tell my remaining fuel level in the tank, and I like that "feature".

      Hi, I recently bought a used 2014 Yz250f (efi bike) and i have been having a problem with it. So i bought the bike from a guy who raced motocross, he kept the bike in tip top shape. When i got the bike, it had a fresh top-end with a high compression piston, and stage two hotcams and a aftermarket exhaust systems. I race a mix of woods and moto races so i figured i could just add a few things for the woods and it would be set to go. When i was riding the bike before buying it, the seller mentioned that the bike almost "hesitates" when going from low to high rpms, he said that this had something to do with the new sprockets but to just stay on the gas. i bought the bike not thinking much about that because it was all around a really nice bike but now i cannot for the life of me figure out what is a causing that bog. On a moto track you hardly notice it because your always riding in the top end of the rpm range, however in the tight woods it makes the bike difficult the ride. It almost feels like there is a gap inbetween the bottom and top end powerwise, and you have to roll on the throttle real smooth in order for it to not sputter. If your going slow and then try and grab throttle quickly (to get over a log for example), it sputters out and there is no power. I tried giving the bike more bottom end power by adding a bigger sprocket, which gave more bottom end but didnt make the bog go away. Then i bought a GYTR Power Tuner, thinking i could retard the Ignition timing and move the power to the bottom end. I haven't gotten to test it a ton yet, but so far maps have helped take away the bog. Aside from that the bike runs perfectly, i have looked online and found no one else who seems to have had this problem which is why i am posting this. Any ideas would be greatly appreciated, as i have no clue what to do next, Thanks.

      Seeing if I can use this method on my 450 of securing in the back of my truck
       
      I will not be using the front wheel mount in my truck***.  Only used as a test anchor point for pictures and compression. 
      The ratchet strap ends will be attached to the inside of my truck bed.  The other end to the blue strap -they will pull down at more if a 45 degree anger, not the 5-10 degree straight down in the pictures 
       
      so, where i have my blue straps, will that damage the forks, frame or suspension in any way?
       
      i have too many cables running on and around my handle bar to strap it down from up there.
