Yz426 quick throtle bogs and dies but slow throtlei revs fine


Or it could be the air induction system. an induction system for a 250 will be restrictive when used to allow a 426 to try and breathe.

What is the starting procedure?


Start with the choke on full press the fuel siphon button till the lines are full of fuel. pull handle until it tries to start but stops. move the choke to half then start again. let it run for 60 seconds on full. don't move the choke to full or it will stop. Either slow the revs and then put the choke on full or keep the revs high and slowly move the choke to full (to allow the governor to slowly advance with the new revs)

I have a 1997 jimmy. When it's cold, it runs and revs up fine. Once it's warm however, if you give it the gas slowly it will rev and hold fine but if you try to work the pedal in a normal way it bogs and...


This almost sounds like the big vacuum line that runs off the back of the throttle body, the one that controls the PCV valve. I would check that first, also clean the PCV valve (should rattle when shaken), it may be stuck open, and look at the vacuum lines that run behind the brake master cylinder, these often get rotten, and are cheap to replace.

A vacuum guage should read between 17 and 22, and, if low may indicate a large vacuum leak. Start there.

My '94 yamaha waverunner 3 runs great for the first 30 minutes. After that it will run fine at idle and just above but the rest of the throttle it just bogs, like it is running out of gas or has some kind...


Could be a bad temp sensor. The bog is a rev limiter to keep engine from running full throtle when hot or when there is another problem. You can bypass the temp sensor and see if that takes care of problem. The parts about 100.00. I disconnected mine a now run a temp gauge which I mounted on the right side just above oil gauge.

Check for a loose connection by the carb. Sounds like its sucking air.

I just fixed one of these. Starts, but won't throttle up, sounds labored.
I checked compression, exhaust for carbon build up, spark, and even the carburator for bad gummed up gas. All were fine.
What I did to fix it was...
You need to remove the high and low speed adjustment screws on the Zama carb. They are blanks, and have no slot for a screw driver. I used a roll pin that the inside diameter fit snug on the outer diameter of the ajustment screw head, and turned it with a pair of needle nose pliers. I remove them (One at a time) and cut a slot in the head with a hacksaw, to allow for future adjustment. Back them both out one full turn from seated, and then tweek to get it to run. The low speed is for idle (Out to richen), and the high speed is for wide open throttle. It's closest to the air filter.
